Comparison Overview – Nikon D3100 vs D7000

The Nikon D3100 is the 2nd entry-level amateur DSLR camera in the Nikon D3XXX series. It replaced the Nikon D3000 which was the flagship camera in that series.

The Nikon D7000, on the other hand, is the first installment of mid-range semi-pro DSLR cameras in the Nikon D7XXX series. It replaced the Nikon D300 and the Nikon D90.

The D7000, therefore, is higher than the D3100 in terms of their camera category. This is evident as the Nikon D7000 incorporates certain features that the amateur camera lacks.

One striking difference that is visibly noticeable is the D7000’s body. It is made from a magnesium alloy which readily seals it from environmental factors such as rain, dust, etc. The Nikon D3100 lacks this environmental sealing feature.

A distinct feature that gives the D3100 a slight advantage; which is a plus to flash photographers is the ‘flash sync port’. This feature is absent in the semi-pro camera.

Both cameras do not deliver when it comes to connectivity: They lack built-in Wi-Fi, built-in Bluetooth, and built-in GPS features.

Price/Value Ratio – Nikon D3100 vs D7000

In terms of price, as one would expect, the Nikon D7000 costs more. This is obviously because of its higher category.

Due to this, not everyone may be able to afford the Nikon D7000. On the flip side, the Nikon D3100 is relatively cheap and can be afforded by nearly everyone.

Looking at their prices in respect to the value they offer, both cameras can be said to offer adequate value for money.

Nikon D3100 vs D7000 – Common Features

This section is dedicated to discussing the common features of the D3100 and the D7000.

Sensor Type and Format

One major feature in every camera is its sensor. A camera’s sensor plays a major role in determining the image quality produced by a camera.

Hence, the kind of sensor used matters a great deal as it influences the performance level.

The Nikon D3100 and the Nikon D7000 are both fitted with the APS-C sensor format. The Nikon Company prefers calling it the DX-format.

In terms of size, the APS-C sensor format is considered to be a medium-sized sensor. The APS-C is larger than the 1 inch and four third sensor formats but smaller than the full-frame and medium sensor format. This is important because the size of the sensor affects its performance level.

These cameras also make use of the same CMOS sensor type. This is commonly found in most Nikon cameras.

Although both cameras are Nikon cameras, the sensor of the D7000 is made by Sony and not Nikon like that of the D3100.

Anti-Aliasing Filter

The anti-aliasing filter is found directly before the sensor. It is also known as the low pass filter. The job of this filter is to stop moiré occurrence in captured images.

Moiré in an image is the appearance of unique patterns of lines and dots. This is usually because these repetitive patterns on the images captured are higher than the resolution of the camera’s sensor.

Hence, cameras that possess low sensor resolution tend to experience moiré than those with higher sensor resolution.

The Nikon D3100 and the D7000 are both fitted with an anti-aliasing filter to prevent moiré occurrence.

Despite the advantage of an anti-aliasing filter, its negative effects still affect image quality a great deal. To effectively reduce the repetitive patterns that might occur, the filter blurs these lines and spots. This, in turn, reduces the sharpness as well as details of the final image captured.

Newer cameras with advanced sensor technology have been able to overcome this moiré occurrence.

Lens Mount and Lenses

The Nikon D3100 and the Nikon D7000 make use of Nikon’s exclusive Nikon F lens mount.

The lens mount of a camera is found between the body of the camera and the lens. It, therefore, holds the lens in place.

The type of lens mount used by a camera determines the number and types of lenses that the camera can make use of.

The Nikon F lens mount allows both cameras in this comparison to make use of 302 native lenses and 88 optical stabilization lenses.

Video Capture

Apart from capturing still images, these cameras can record moving images as well.

They can shoot a 1920 x 1080 full HD video resolution at a speed of 24 frames per second.

The Nikon D3100 can capture MPEG-4 video format while the D7000 can do the same and also capture in the H.264 video format as well.

Viewfinder Type

The viewfinder allows one to frame and control the shots about to be taken.

The type of viewfinder used by a camera determines the efficiency at which the photographer can frame his/her pictures.

In terms of the viewfinder, the similarity between the Nikon D3100 and the Nikon D7000 is that they make use of the same viewfinder type. All other aspects of the viewfinder used by these cameras are different.

A camera either makes use of an optical viewfinder or an electronic viewfinder which is also known as a digital viewfinder.

The cameras in this comparison are fitted with the former which is the optical viewfinder. This has its advantages in the sense that an optical viewfinder does not require power for it to function. The electronic viewfinder, on the other hand, cannot function without consuming the camera’s battery power.

Hence, the D3100 and the D7000 avoids extra and unnecessary power consumption.

The fact that these viewfinders are regarded as eye-level viewfinders also has its perks. One of such is that the user can still frame his/her shots despite the intensity of the sun’s rays. He/she can shoot no matter how bright the sun is.

Screen

The screen is a feature that helps one to review captured images, display the camera’s menu and settings. It can also be used as a live viewfinder.

Therefore, thanks to the numerous functions of the display screen, a good number of folks prefer cameras that have a large screen.

The Nikon D3100 and the D7000 come fitted with a 3 inches LCD screen which is fair enough.

These screen sizes allow proper viewing of captured images as well as the camera’s menus and settings.

Another similarity between these cameras’ screen feature is that both screens are fixed in nature. They do not have the articulating screen feature.

Furthermore, these screens are also non-touch screens.

We discuss the importance of these features in the common cons section later on.

More Common Features – Nikon D3100 vs D7000

Image Processor

Since both cameras belong to the same technological generation, they make use of the same image processor.

The image processor serves as ‘the brain’ of the camera and is responsible for image processing speed, video resolution, and capture. It also helps in reducing battery consumption as well as many other functions.

The Nikon D3100 and the Nikon D7000 make use of Nikon’s EXPEED 2 image processor.

Built-in Flash

It is not always that one gets the advantage of shooting in well-lit conditions. Sometimes, the lighting condition can be very poor and at such times another light source must be provided.

Most cameras like the Nikon D3100 and the D7000 provide this light thanks to their built-in flash feature.

This feature is used to illuminate subjects properly in poorly lit conditions to provide for a clear and sharp image.

Both cameras’ flash can be used with Nikon’s Creative Lighting System. They also have a 12.0m range when shot at ISO 100.

Besides, the built-in flash feature takes away the constant need to go about with an external flash. This is important as an external flash tends to increase the camera’s weight when attached.

Furthermore, one on a tight budget can make do with the built-in flash without stressing much on getting an external flash.

Hot Shoe (External Flash)

The hot shoe feature is a platform that is located on the top of cameras that permits one to attach certain accessories to the camera. The Nikon D3100 and the Nikon D7000 both possess this feature.

One of the major accessories usually attached to the hot shoe is an external flash. Because it is readily used, the hot shoe is usually called an external flash shoe as well.

Despite the handiness of the built-in flash feature, they do not deliver as great as an external flash.

Once you get over the fact that you’ll have to spend more and also carry more weight around, the external flash readily does better than your built-in flash. It has more flash power and is more versatile to use.

HDMI Port

The Nikon D3100 and the Nikon D7000 both have a mini HDMI port feature.

With this, you can conveniently connect these cameras to a larger screen with the use of an HDMI cable.

A larger screen allows for a larger view hence angles and points that need editing can be easily detected. Generally, viewing images on a larger screen is a better experience than using the 3 inches screen both cameras provide.

Bulb Shutter

The bulb shutter feature enables you to keep the shutter manually open for longer exposures.

The Nikon D3100 and the D7000 both possess the bulb shutter feature.

Distinct Features – Nikon D3100 vs D7000

In this section, we discuss the features that the Nikon D3100 possess which the Nikon D7000 lacks and vice versa.

Nikon D3100 Distinct Features – Nikon D3100 vs D7000

Flash Sync Port

A major difference between the Nikon D3100 and the Nikon D7000 is that the former possesses a flash sync port which the latter lacks.

With a flash sync port, the D3100 can be connected to an off-camera flash with the use of a cord. The off-camera flash could be a flash unit or just several external flashes.

A signal is sent to these flashes via the cord when the shutter is pressed thereby triggering the flashes to light up. The flashes used can be placed at different positions around and within the scene to provide excellent lighting.

This gives the Nikon D3100 an edge over the D7000 as a better flash photography camera. This feature is also employed a great deal by portrait photographers.

Nikon D7000 Distinct Features Nikon D3100 vs D7000

Built-in Environmental Sealing

The environmental and weather conditions sometimes make it challenging for one to capture an image. Factors such as rain, fog, dust, snow, etc tend to affect and interfere with the quality of the image captured.

However, the Nikon D7000 is designed to fully combat these challenging environmental factors. It is equipped with a built-in environmental sealing feature that protects it from these issues.

The photographer can easily shoot and capture images despite such tough weather conditions.

Top LCD Screen

The top LCD screen is a small screen found on top of certain cameras like the Nikon D7000.

It enables the user to get faster and easier access to the camera’s major settings and controls.

It comes quite handy when one is making use of a tripod stand during image capture.

Built-in Intervalometer

The Nikon D7000 possesses a built-in intervalometer feature. Time-lapse video recordings can be created with the help of this feature.

A time-lapse video is a short video made from capturing several shots of a particular subject at different time intervals.

These pictures are then brought together and made into a short video. Blooming plants, sunset, sunrise, traffic in the city videos, etc are created using this feature.

Dual Card Slot Storage

Single card slot storage is good but dual card slot storage is better.

Hence, the Nikon D7000 is better in its storage options as it possesses dual card slot storage whereas the D3100 uses a single card slot storage feature.

There are many advantages this feature offers the camera: One is more storage space.

The dual card slot storage can house two SD cards hence double the storage capacity of the D3100.

Also, it offers storage flexibility. The user can decide to store only videos on one card and pictures on the other. Or he/she could save only RAW formats on one card and JPEG on the other etc.

Lastly, it offers one rest of the mind. The other SD card can be used as a backup for the files in the primary SD card.

Therefore when a loss of files occurs in the SD card, the other card can be used to restore the lost and damaged files.

Microphone Port

We already established that both cameras can record videos. It is normal that during such video capture, audio has to be recorded as well.

These cameras perform this thanks to the built-in microphone feature they both possess.

However, it has been readily discovered that these microphones do not deliver quality audio.

Hence, cameras like the Nikon D7000 are fitted with a microphone port feature.

The microphone port allows the connection of an external microphone to the camera.

This microphone is used to record quality audio which the built-in microphones cannot record.

AE Bracketing

The AE bracketing feature allows the Nikon D7000 to capture images even in tough lighting conditions and HDR mode.

This feature automatically alters the camera’s settings to fit the lighting condition of the particular environment wherein the photographer is shooting in.

AF Micro Adjustment

The AF micro-adjustment feature is used for fine-tuning. It is used to adjust each lens to acquire a precise focus.

The Nikon D7000 possesses this feature.

AF Motor in Body

With the AF Motor in body feature, the Nikon D7000 can autofocus with any lens that it is attached to.

Cameras that lack this feature cannot carry out autofocus with all the lenses available for their use.

The video below teaches you how to use Nikon’s Autofocus controls.

Distinct Pros – Nikon D3100 vs D7000

In this section, we deal with the advantages the Nikon D3100 has over the Nikon D7000 and vice versa. Here although both cameras possess the same feature, one has a better performance level than the other.

Nikon D3100 Distinct Pros – Nikon D3100 vs D7000

Smaller Size

When it comes to camera size and people’s preference, most folks tend to go for smaller cameras. However, there are a few who want bigger cameras as they feel it is sturdier and balanced in their hands.

Yet, smaller cameras come with more advantages than bigger ones.

They are easier and more convenient to carry. During travels, they can be easily packaged than bigger cameras.

The Nikon D3100 is smaller than the Nikon D7000. The fact that the former is an amateur camera while the latter is a semi-pro camera account in part for this size difference. This is because most semi-pro cameras are usually larger than amateur cameras.

The D3100 has a size dimension of 124 x 96 x 75mm while the D7000 measures at 132 x 105 x 77mm. Therefore, the Nikon D3100 is 8mm narrower, 9mm shorter and 2mm thinner (16% smaller) than the Nikon D7000.

Lighter Weight

Not only is the Nikon D3100 the smaller camera, but it is also the lighter camera.

The type of body material used by a camera plays a huge role in determining the camera’s final weight.

Just like the preference for smaller cameras instead of bigger ones, most folks prefer a lighter camera than one that is heavy.

The reason is not far-fetched as heavier cameras tend to become burdensome over time as one continues shooting.

Furthermore, the addition of other accessories such as lenses, external flashes, external microphones, etc can increase significantly the camera’s overall weight.

The Nikon D3100 and the Nikon D7000 weigh 505g and 780g respectively. This means the D3100 is 35% and 275g lighter than the D7000.

Cheaper

The cost of a camera has a huge say as to whether a customer purchases a camera or not.

A camera with an expensive price means very few will be able to afford it. Consequently, a camera with a cheaper price can be readily afforded by even those on a low budget.

Hence, cheaper cameras are more in circulation when compared to expensive cameras.

The Nikon D3100 is the cheaper of the two cameras. Considering the launch price of both cameras, it was found to be 60% cheaper than the D7000.

This shouldn’t be much of a surprise as it is an amateur camera while the Nikon D7000 is a semi-pro camera: The category which a camera belongs to is a major influence on the camera’s price.

Larger Sensor Pixel Area

The sensor pixel area of a camera is a measure of the individual pixel’s light capturing ability.

Cameras with larger sensor pixel area can capture more light than those with smaller sensor pixel area.

Being able to capture more photons tends to influence the sensor’s dynamic range. However, smaller sensor pixel areas make for increased sensor resolution.

The Nikon D3100 and the Nikon D7000 have a sensor resolution of 25.12µm2 and 23.04µm2 respectively. In effect, the D3100 has a 9% larger pixel area.

Larger JPEG Buffer

The camera’s buffer has a major influence on shooting in burst mode.

Burst mode also known as continuous shooting mode allows the photographer to capture several pictures non-stop within a period.

The buffer serves as a temporary storage area where these pictures are stored before they are moved to permanent storage.

As far as the buffer is not filled up the photographer can continue shooting. However once the buffer is filled up, continuous shooting stops as the camera has to move the pictures to permanent storage.

During this short period, the camera becomes inactive as the images are processed and stored. Once this is done, the photographer can resume shooting in burst mode.

The Nikon D3100 and the D7000 have a JPEG buffer of 100 and 19 shots respectively. In other words, the D3100 can shoot 100 JPEG pictures in burst mode before the buffer gets filled up.

The D7000, on the other hand, can shoot just 19 JPEG pictures in burst mode before its buffer gets filled up. The difference between these cameras’ JPEG buffer size is quite vast.

Nikon D7000 Distinct Pros – Nikon D3100 vs D7000

Higher Sensor Resolution

The sensor resolution is a measure of the sensor’s sensitivity in detecting and capturing well-detailed images.

The sensor resolution is usually measured in megapixels hence most folks simply refer to it as megapixels.

The D7000 has a better sensor resolution than the D3100. The semi-pro camera has 16.2 megapixels while the amateur camera boasts 14.2 megapixels.

Hence, the Nikon D7000 has 2.0 more megapixels than the Nikon D3100 which makes it 7% higher.

Cameras that possess higher sensor resolutions are capable of printing large-sized images and can crop freely without the image quality being affected.

Blurred and grained images are the usual occurrence when cameras with low sensor resolutions print out large images or crop images extensively.

Although the D7000 has a slight advantage over the D3100, its sensor resolution is still low.

Hence, we do not recommend printing large images or extensive cropping with this camera.

Higher Screen Resolution

Another resolution wherein the Nikon D7000 does better than the Nikon D3100 is in terms of screen resolution.

The screen resolution measures the details a camera’s screen can effectively display. This is usually measured in dots.

The D7000 and the D3100 possess a screen resolution of 921,000 dots and 230,000 dots respectively.

The screen resolution of the Nikon D3100 is quite poor in our opinion and it is the same that resonates in the camera world.

Higher Maximum ISO

A camera’s ISO is a measure of the sensor’s sensitivity in making use of available light and creating an image with it.

A camera with a high ISO has a higher tendency to produce clear images in spite of poor light conditions.

Most cameras have an ISO range and the setting that can be altered to fit the lighting condition of a particular area.

For the cameras in this article, the Nikon D7000 has a higher maximum range. It records a maximum ISO value of 6400 which can still be expanded to 25600.

The D3100, on the other hand, has a maximum ISO of 3200 which can be expanded to 12800.

The minimum ISO of these cameras is the same at 100.

All you need to know about Nikon cameras’s auto ISO.

Better Sensor Performance

There are three major aspects of the sensor that are used to measure its performance level.

When these aspects are compared in both cameras, the Nikon D7000 comes out on top over the Nikon D3100.

These sensor aspects are the color depth, the dynamic range, and the low light ISO. Let’s discuss these three sensor measurements briefly.

When we speak of a camera’s color depth, we refer to the sensor’s sensitivity in detecting unique colors.

Since the D7000 has a color depth of 23 bits which is more than the D3100’s 22.5 bits, the former will produce images with richer colors.

Also, a better color depth has a greater influence on the quality of portrait images. This is why the color depth is also referred to as the DXO portrait.

The dynamic range is the sensor’s ability to detect the details of the lightest and darkest points in an image.

The Nikon D7000 and the Nikon D3100 have a dynamic range of 13.9EV and 11.3EV respectively.

Due to this, the D7000 is capable of producing better-detailed images than the D3100.

The dynamic range also has a significant effect on the quality of landscape images: Hence, it is called the DXO landscape.

The last sensor measurement is the low light ISO. This is responsible for the sensor’s ability to detect and also capture clear images in low light conditions.

The higher the low light ISO value, the better equipped the camera is to get clear images in low light. Also, such cameras can easily avoid the occurrence of grain and noise when images are captured.

The low light ISO has a major impact on image quality captured indoors and also at sports events. Hence another name for the low light ISO is DXO sports. 

The Nikon D7000 and the Nikon D3100 have a low light ISO of 1167 and 919 respectively. Therefore, the D7000 does much better than the D3100 in this regard.

When these three sensor measurements are calculated together, the Nikon D7000 has an overall sensor performance or sensor quality of 80. The Nikon D3100 was able to attain an over sensor performance of 67.

These sensor measurements and results are done by the DXO mark company.

Better Battery Life

The Nikon D7000 makes use of the EN-EL15 power pack battery with an energy capacity of 1900mAH. This allows the camera to capture 1050 shots before shutting off after the battery is fully charged.

In contrast, the Nikon D3100 uses the EN-EL14 power pack battery with an energy capacity of 1000mAh. This battery allows the D3100 to capture 550 shots after being fully charged.

Looking at this, we discover that the D7000 has the advantage of 500 extra shots than the D3100. Therefore one can shoot for longer periods with the semi-pro camera.

Better Viewfinder

The D7000 has a better viewfinder: This is due to three major reasons which we would briefly talk about.

First of all, the D7000 makes use of a pentaprism material instead of a pentamirror material that the D3100 employs.

The advantage this affords the Nikon D7000 is that more light can easily pass through the pentaprism material than the pentamirror. Hence the image transmitted to the viewfinder is much clearer and brighter.

Another reason is that the Nikon D7000 has better viewfinder coverage. It has 100% viewfinder coverage while the Nikon D3100 has 95% viewfinder coverage.

What this means is that the viewfinder of the D7000 can capture more frame area than the D3100.

Lastly, the semi-pro camera has better viewfinder magnification.

The higher the viewfinder magnification the larger the images appear as though when looked at with the physical human eye.

The Nikon D7000 and the Nikon D3100 have a viewfinder magnification of 0.63x and 0.53x respectively.

Larger Sensor

The Nikon D7000 has a sensor that is 4% larger than that of the Nikon D3100. It has a size dimension of 23.6 x 15.7mm versus the 23.1 x 15.4mm sensor size of the D3100.

With this difference, the D7000 has an advantage over the amateur camera. These advantages include being able to deliver better-detailed images.

Also, a larger sensor has a significant influence on the performance level of the color depth, dynamic range, low light ISO and depth of field control.

Due to the size difference not being so much, the format factor and the native aspect ratio of both sensors are the same.

They have a format factor and a native aspect ratio of 1.5 and 3:2, respectively.

Faster Continuous Shooting Speed

The cameras in this comparison can effectively shoot in burst mode as we mentioned earlier. We also said that having a larger buffer is important for burst mode shooting.

Another important factor that makes your burst mode shooting wonderful is the continuous shooting speed feature.

While the buffer serves as the temporary storage area, the continuous shooting speed determines how many images you can capture per second.

The Nikon D7000 has a clear edge here as it has a continuous shooting speed of 6 frames per second (fps). The Nikon D3100, on the other hand, can capture just 3 frames per second.

Therefore, for every second of shooting, the D7000 will capture 3 more images than the D3100. This shooting will continue every second until the buffer of the camera gets filled up.

More Focus Points

Focus points allow the photographer to place much focus and emphasis on certain points within the frame. This brings about better detailed and sharper images.

These focus points are predetermined by the camera’s manufacturer. The photographer can only select which and how many of them to use per time.

The Nikon D7000 and the Nikon D3100 have 39 and 11 focus points respectively.

The D7000 also has more cross-type focus points. It has 11 of such while the D3100 has just 1.

\The difference between the regular focus points and the cross-type is that the latter can detect in horizontal and vertical lines.

All you need to know about autofocus points is explained in the next video.

Faster Shutter Speed

The Nikon D7000 has a faster shutter speed of 1/8000s. The Nikon D3100, on the other hand, manages a shutter speed of 1/4000s.

Longer Shutter Life

There is an expected lifetime whereby your shutter is expected to last before the need arises for you to change the shutter mechanism.

This is referred to as the camera’s shutter life.

The Nikon D7000 and the D3100 have a shutter life expectancy of 150,000 actuations and 100,000 actuations respectively.

Less Shutter Lag

The time interval between when a shutter is pressed to capture and image and the actual time the image is saved is called shutter lag or shutter delay.

The Nikon D7000 and the Nikon D3100 have a shutter lag of 238ms and 279ms respectively.

Hence, the D7000 has less shutter lag and is capable of resuming shooting faster than the D3100 after capturing an image.

More Telephoto Lens Reach

When these cameras make use of a telephoto lens, the Nikon D7000 can cover a wider and farther area than the D3100.

The Nikon D7000 has a telephoto lens reach of 158mm versus the 83mm reach of the Nikon D3100’s telephoto lens.
