What Situation Is Each Best For? – Nikon D3100 vs D3000

Nikon D3100 Nikon D3000
The Nikon D3100 will serve better for portrait photography than the Nikon D3000.  

Its possession of a higher sensor resolution makes it capable of delivering well-detailed quality images which is important for this kind of photography.    

Furthermore, the presence of the flash sync port allows it to connect to more external flashes than the D3000 can manage.
Second-rate performance.
When both cameras are compared as to which will do better for street photography, the D3100 has the edge thanks to two features.  

First, it has the live view feature which allows for flexibility in capturing difficult angles.  

Secondly, the face detection focus feature makes it easy to detect human faces and apply the right amount of exposure necessary.  

These features enhance the Nikon D3100’s efficiency for street photography.
Second-rate performance.
For a camera to be efficient as a sports photography camera, it must be able to capture fast-moving subjects. Shutter speed, continuous shooting speed, and focus points are features that allow a camera to do so.  

On all accounts, the D3100 excels above the Nikon D3000. Hence, it is better for sports photography.  

Furthermore, it has a longer battery life, which means you can shoot for longer periods and capture more images.
Second-rate performance.
Cameras used by many daily photographers usually have one thing in common; they are not heavy-weight cameras.  

Even when using professional high-end cameras, this set of photographers still choose cameras within that category that are lighter.  

With the Nikon D3100 being the lighter and even smaller of the two cameras in focus, it is a better option for this kind of photography. Its thicker body allows users to have a firm grip when using this camera as well.
Second-rate performance.
Landscape pictures are usually well-detailed as they must reflect the live-like details of the actual landscape.  

The D3100 can produce well-detailed images as a result of its higher sensor resolution.  

The live view feature enhances the photographer’s ability to frame such images; giving them the right exposure required.  

Therefore, the Nikon D3100 is a better landscape camera than the Nikon D3000.
Second-rate performance.

Common Features – Nikon D3100 vs D3000

In this section, we discuss the features found in the Nikon D3100 and the Nikon D3000. Here, we reveal how similar these cameras are.

The D3100 and the D3000 have the following similarities:

i. Sensor Format
ii.Anti-Aliasing Filter
iii. Lens Mount and Available Lenses
iv. Viewfinder
v. Screen
vi Continuous Shooting Speed
vii. Focus Points
viii. Built-in Flash
ix. Hot Shoe (External Flash Shoe)
x. Storage
xi. USB Port
xii. Bulb Shutter

Sensor Format

The sensor is a prominent part of a camera that has a major role in deciding the overall quality of the image produced. It is responsible for capturing light into the camera necessary for image production.

Every camera makes use of a particular sensor format which is a categorization of the sensor size. In other words, the sensor format refers to the size category of the sensor. That means two sensors may have the same sensor format but not the same sensor dimensions.

The sensor format determines the size of the image a camera can capture. It also determines to some extent the type of lenses a camera can employ.

The cameras in this comparison make use of an APS-C sensor format. The APS-C is regarded as being medium-sized because of its relative size when compared with other sensor formats.

Anti-Aliasing Filter

Sometimes you notice on some captured images certain repetitive patterns either of lines or spots. This repetitive pattern is known as moiré.

Moiré occurs when the resolution of the subject captured that has those patterns are higher than the sensor resolution of the camera. Therefore, cameras with low sensor resolution are prone to this occurrence.

The Nikon D3100 and the D3000 sensor resolutions are low which leaves them susceptible to the appearance of moiré. Fortunately, these cameras are fitted with an anti-aliasing filter.

The anti-aliasing filter aka low pass filter is found in front of a camera’s sensor. Its job is to prevent the occurrence of moiré. It does this by reducing the amount of light that gets to the sensor, thereby blurring those repetitive patterns.

The downside to this is that the captured image may be moiré-free, but image detail and sharpness is lost. Hence, a good number of photographers prefer cameras that lack this feature.

Newer cameras tend not to have the AA filter because improved sensor technology has overcome moiré. Cameras with high resolution do not have it as well. 

Lens Mount and Available Lenses

The lens is the part of the camera that serves as the ‘eye of the camera’. Its job is to capture the subject in the frame.

As important as it is, in DSLR cameras, the lens is dependent on the lens mount. This is because the lens mount is that which attaches the lens to the camera’s body.

The lens mount is found between the lens used and the camera’s body, and it holds the lens in place. Therefore, the lens mount determines the type and number of lenses a camera can make use of.

The Nikon company fits its cameras with exclusive lens mounts: One of such is the Nikon F lens mount. This is the lens mount found in the cameras in focus.

This lens mount allows these cameras to make use of 304 native lenses and 101 image stabilization lenses. Hence, users of these cameras have a variety of lenses to choose from.

One lens we will recommend you to choose from the 304 native lenses available to these cameras is the Nikon AF-S DX NIKKOR 35mm f/1.8G Lens with Auto Focus.


When the viewfinders of the D3100 and the D3000 are compared, we discover they are the same in every way. These cameras are equipped with an optical pentamirror viewfinder with a coverage of 95% and 0.53x magnification.

The viewfinder is used to frame a shot that is about to be captured. It ensures the subject is not out of frame, or wrongly framed.

Making use of an optical viewfinder saves these cameras from unnecessary battery consumption. This is because this type of viewfinder does not require battery power to function, unlike an electronic viewfinder.

The pentamirror material used in making the viewfinder is a bit of a disadvantage: It does not allow the passage of sufficient light. This is in contrast to the pentaprism material that allows sufficient light through the viewfinder. Therefore, the images transmitted via the pentamirror viewfinder aren’t as bright as that which the pentaprism produces.

With a 95% viewfinder coverage, the user of these cameras has a wide field of view that allows one to capture more of the subject’s surroundings. The 0.53x magnification, although not excellent can deliver a bold image during framing.

The screens of the Nikon D3100 and the Nikon D3000 are equally the same in every regard. They are both fitted with a 3 inches LCD non-touch fixed screen with 230,000 dots resolution. Don’t worry, we’ll break down what that means.

The screen is essential in a DSLR camera as it is used to view the camera’s menu and settings. It is also used to view captured images and even watch videos. Some screens can be used as a live viewfinder.

For clear viewing, the size of the screen must be large enough and this is what these cameras offer. Despite being amateur cameras, these cameras possess 3 inches’ screens. The larger the screen size, the easier viewing becomes. Furthermore, it enables one to detect angles that need editing better.

These cameras miss out on the many benefits the touchscreen feature would have offered. The touchscreen feature allows you to interact with your camera the way you would your smartphone.

With a tap, a swipe, a pinch, you can navigate through your camera’s menu and change its settings. It can even be used while capturing an image; provided your camera has the live view mode.

Cameras with the touchscreen tend to have fewer buttons which enhances the ergonomics and design of such cameras.

Another screen feature missed out on is the articulating screen as their screens are fixed. The articulating screen cannot be restricted as it can be twisted, swiveled, rotated, and turned to give you the shooting and viewing flexibility you desire.

Capturing difficult angles with this screen type is easier. Hence, street, wildlife, and even landscape photographers enjoy this feature when capturing tricky angles. Vloggers benefit from this screen type as well when making their videos. And if you love selfies, the articulating screen makes it all too easy.

The last aspect of these cameras screen is the screen resolution. It refers to the number of detail a screen that efficiently displays. Hence, a screen with high resolution is bound to produce well-detailed images with richer colors.

The 230,000 dots screen resolution of these cameras is low. Therefore, don’t expect an excellent image display from these cameras.

Continuous Shooting Speed

Both cameras in this article can shoot in burst mode otherwise known as continuous shooting mode. In this mode, you can capture several images non-stop for a while.

The feature that enables one to capture more images during this period is known as the continuous shooting speed. It refers to the number of images captured per second. Therefore, the faster the continuous shooting speed, the more images a camera can capture per second.

The Nikon D3100 and its predecessor have a shooting speed of 3 fps. They can capture just 3 images per second.

Focus Points

Focus points are the points within a frame whereby a camera can create more focus on and enhance the overall image quality.

The Nikon D3000 and its successor have 11 focus points at their disposal. The center focus point is a cross-type focus point.

Built-in Flash

The built-in flash allows the photographer to illuminate a subject and its surroundings. In low light conditions, this built-in flash comes in handy.

The cameras in comparison are equipped with this handy feature. The flashes of these cameras can be used with Nikon’s Creative Lighting System. They have a 12m range when used at ISO 100.

Hot Shoe (External Flash Shoe)

Apart from being equipped with a built-in flash, these cameras can also make use of an external flash shoe. It is more versatile and efficient than the built-in flash.

Nevertheless, these cameras would not be able to make use of an external flash shoe if they lacked the hot shoe. The hot shoe is a platform found on top of these cameras that allows the attachment of accessories like the external flash.


These cameras can store captured images, but do not make use of internal memory. Rather, these cameras are fitted with a single card slot storage.

An SD card can be inserted into this slot to facilitate image storage. The Nikon D3100 makes use of SDXC cards like this SanDisk 128GB Ultra SDXC UHS-I Memory Card. While the Nikon D3000 makes use of SDHC cards like this SanDisk 32GB Ultra SDHC UHS-I Memory Card.

Certain cameras are fitted with dual card slots instead of a single card slot. Such cameras have more storage space, options, and flexibility.

USB Port

The cameras in focus are equipped with a USB 2.0 port. This port feature allows these cameras to connect to other devices such as your laptops via a USB cable. When this connection is made, files can be transferred from the device to the camera and vice versa.  

Bulb Shutter

The Nikon D3100 and the Nikon D3000 are equipped with the bulb shutter. This feature holds the shutter manually open for long exposures.

Flash Sync Port

The D3100 is fitted with a flash sync port. This port allows the camera to connect to several off-camera flashes.

Connecting a cable is connected to this camera, the connected flashes are lighted when the shutter button is pressed. Because several flashes can be used at once, this feature is employed by portrait and studio photographers.

Live View

Another feature which the Nikon D3000 lacks is the live view feature. Thanks to this feature, the Nikon D3100’s screen can be used as a live viewfinder.

You can use it to frame your shots. It helps capture difficult angles. Furthermore, this feature allows you to see the focus points on the screen which you cannot see when using the traditional viewfinder.

Unique Pros – Nikon D3100 vs D3000

In this section, we discuss the advantages we have over the other.

Nikon D3100 Unique Pros

Which has a Higher Sensor Resolution D3100  or D3000?

The D3100 has a higher sensor resolution than the D3000. It has a sensor resolution of 14.2 megapixels while the Nikon D3000 has a sensor resolution of 10 megapixels. Hence, the Nikon D3100 it will produce a better detailed image.

The difference in these cameras’ sensor resolutions accounts for the difference in their pixel pitch. The Nikon D3100 and the Nikon D3000 have a pixel pitch of 5.01µm vs 6.11µm respectively.

The sensor resolution of a camera refers to the sensor’s ability to detect and produce detailed images. Hence, a higher sensor resolution will produce a well-detailed image.

As much as the sensor resolution has a major impact on image quality, it is not the only responsible factor. Other factors include composition, lens used, lighting, etc.

Which has a Better Sensor Performance D3100 or D3000?

The D3100 has a better sensor performance than the D3000. It has a color depth of 22.5 bits, 11.3 EV dynamic range, and 919 low light ISO that gives it an overall sensor performance score of 67.

The Nikon D3000, on the other hand, has a color depth of 22.3 bits, 11.1 EV dynamic range, and 563 low light ISO bringing it to an overall score of 62.

Hence, the D3100 has 0.2 bits color depth, 0.2 EV dynamic range, and 0.7 stops low light ISO more than its predecessor.

The DXO mark over the years has dedicated their time to testing camera sensors and releasing an overall score that reflects their performance level. This overall score is an aggregate of the camera’s color depth, dynamic range, and low light ISO.

In case, you’re wondering what these terms mean, we think some quick definitions are in order.

The color depth refers to the sensor’s sensitivity in detecting and producing distinct colors. It is responsible for color richness in captured images.

The dynamic range is the sensor’s ability to detect details in the brightest and darkest points within a frame.

The low light ISO is a measurement of the sensor’s sensitivity in low light conditions. In other words, a sensor can produce a clear image despite low light conditions.

We can see that the Nikon D3100 has a wider ISO range and will be more effective in varying light conditions.

A camera’s ISO refers to its sensitivity to produce a clear image with available light. A wide ISO range is an indication of the sensor’s wide sensitivity. It allows the camera to capture clear images irrespective of the light available.

Which has an Improved Image Processor D3100 or D3000?

The D3100 has an improved image processor than the D3000. The Nikon D3000 as an older camera is fitted with the first EXPEED processor. The Nikon D3100, on the other hand, is fitted with the upgrade to the EXPEED; the EXPEED 2.

This newer processor offers the D3100 better noise reduction, improved color accuracy, faster processing speed, and reduced battery consumption.

A camera’s image processor is responsible for its processing speed and performance level. Hence, some refer to it as the ‘brain of the camera’.

The Nikon company makes use of exclusive image processor series known as the EXPEED for its cameras.

Which has a Longer Battery Life D3100or D3000?

The D3100 has a longer battery life than the D3000. The Nikon D3100’s battery is capable of taking 550 shots after a full charge. Whereas, the Nikon D3000 can capture just 500 shots which makes it 50 shots less than the D3100.

The Nikon D3100 makes use of the EN-EL9a 1000mAH battery, while the D3000 is fitted with an EN-EL9a 1080mAh battery.

Which has a Larger JPEG Buffer D3100 or D3000?

The D3100 has a larger JPEG buffer than the D3000. The Nikon D3100 and the Nikon D3000 have a JPEG buffer of 100 shots and 16 shots respectively.

In burst mode, the number of shots you can capture is determined by the camera’s buffer. The buffer is temporary storage where images are stored while shooting in burst mode before being moved to the main storage.

The larger the buffer capacity, the more images you can capture when in this mode. Once, the buffer is filled up, continuous shooting stops as the images are then transferred to the main storage. You can then continue in bust mode after the images are saved.

Which has a Faster Startup Delay D3100 or D3000?

The D3100 has a faster startup delay than the D3000. It has a startup delay of 0.40 seconds, while the D3000 has a startup delay of 0.70 seconds. Hence, the Nikon D3100 has a faster startup of 0.30 seconds.

The D3000 has a better sensor type than the D3100. The Nikon D3100 is fitted with a CMOS (complementary metal-oxide-semiconductor) sensor while the Nikon D3000 uses a CCD (charge-coupled device) sensor.

The table below reveals why the CCD sensor is better than the CMOS sensor:

CMOS Sensor CCD Sensor
Lower light sensitivity. More sensitive to light.
Inexpensive. Expensive.
Produces lower-quality images Produces high-quality images.
It consumes little power. It consumes lots of power.
Prone to images with noise. It has low noise-images.

Looking at the table above, you’ll discover the CCD sensor has 3 advantages while the CMOS sensor has 2. Therefore, we can say the Nikon D3000 uses a better sensor type.

The sensor type refers to the technology employed in manufacturing the sensor. The Nikon D3100 and the Nikon D3000 make use of different sensor technology.

A larger sensor can capture more light into the camera than a smaller one. This, in turn, improves the quality of the produced image. It also enhances the color depth, dynamic range, and low light ISO.

Unique Cons – Nikon D3100 vs D3000

Nikon D3000 Unique Cons

  1. It cannot record videos.
  2. It cannot be connected to a larger screen.
  3. Lacks face detection focus.
  4. No flash sync port.
  5. Live view absent.

Common Pros – Nikon D3100 vs D3000

Nikon D3100 Nikon D3000
Uses Phase Detection Autofocus System The autofocus system which a camera employ is important as it determines how efficient the camera’s autofocusing will be.  

There are two AF systems that cameras can employ. There is the contrast-detection autofocus system and the phase-detection autofocus system. Some cameras employ both.  

The Nikon D3100 employs just one of these AF systems which are the phase-detection autofocus system.  

This AF system is capable of acquiring fast and precise autofocus.   Cameras that use this AF can perform subject tracking and continuous autofocusing which aids one in capturing subjects in motion.
Same as Nikon D3000
Supports RAW Format A captured image can be in the JPEG or RAW format. The JPEG format is commonly used of the two. Therefore, certain cameras cannot shoot in RAW format.  

The D3100 is not one of such; it can shoot images in both JPEG and RAW formats.  

This is an advantage for the camera because RAW images are of better quality than JPEGs. Hence, the user of this camera is rewarded with better quality whenever he/she shoots in RAW format.  

Furthermore, because of their uncompressed nature, images captured in RAW format can be easily edited than JPEG images.  

Capturing in RAW format is great provided you have sufficient storage capacity. Due to the high quality, they take up more storage space than JPEG formats.

Common Cons – Nikon D3100 vs D3000

Nikon D3100 Nikon D3000
Lacks Environmental Sealing The environmental sealing feature protects the camera. It allows the camera to be used in tough weather conditions.  

Cameras with this feature can capture in wet, dusty, windy and even rainy conditions. This is dependent on the camera’s sealing type.  
The Nikon D3100 does not have this feature which is surprising as it is not common with amateur cameras.
Same as Nikon D3100
Poor Shutter Life Expectancy A camera’s guarantee that tells how long it will last is known as the shutter life expectancy. It is a measure of how long the shutter mechanism will last before there is a need to replace it.  

It is measured in actuations which is just the number of shots taken.  

The D3100 has a shutter life expectancy of 100,000 actuations. This is poor considering how many shots some folks capture in a day.  

It is important to mention once again that the shutter life expectancy does not automatically mean the camera will stop working once it hits that number. It is more of a guarantee.  
A word of advice: If you’re purchasing a previously used camera, knowing how many actuations used is important. You wouldn’t want to get a camera that you’ll need to change the shutter after taking just a few shots.
Same as Nikon D3100
No UHS Card Support UHS cards are awesome because they can be used to read, write and transfer files at ultra-high speeds.  

With a UHS card, you can transfer files at a speed of 104MB/s.  

Sadly, the Nikon D3100 does not support the use of these cards.
Same as Nikon D3100
Built-in Wi-Fi Absent The Wi-Fi feature enables wireless connection between the camera and other supported devices.  

With this feature, one can transfer files wirelessly to other devices and receive files from such devices as well.  
You can even print images without cables by connecting to a Wi-Fi printer. Even remote controlling your camera can be achieved with the aid of this feature.  
Exciting use of this feature allows you to share your images directly to your social media platforms from your camera. This eliminates all the trouble of having to get the images to your phone or PC first.  

The Nikon D3100, however, lacks this all too amazing feature.
Same as Nikon D3100
No Built-in Image Stabilization Have you ever seen some captured images that were blurred? This is common with cameras that have a slow shutter speed like the D3100.  

Cameras like this are not fast at capturing subjects in motion which is responsible for the blurred images.  

To counter this occurrence, some cameras are fitted with the image stabilization feature. Like its name, this feature stabilizes your camera to produce a blur-free image.  

One would think, the Nikon D3100 would have this feature since it is prone to producing blurred images; sadly, it does not.

However, with the 101 stabilization lenses at its disposal, one can still perform the stabilization function.
Same as Nikon D3100
Lacks AE Bracketing The D3100 does not have the AE bracketing feature. Therefore, it is not good for shooting multi-exposure HDR.  
This feature automatically adjusts the camera’s settings to the right exposure required for a particular environment the photographer finds himself/herself.
Same as Nikon D3100
No AF Micro Adjustment (Fine Tune) Since the Nikon D3100 lacks the AF micro-adjustment, it cannot fine-tune its autofocus.  

Using this AF feature enhances the camera’s autofocusing ability thereby improving image quality.  
Same as Nikon D3100
Slow Shutter Speed The shutter speed refers to how fast a camera can capture an image.  

A fast shutter speed enables cameras to capture fast-moving subjects. Cameras with fast shutter speeds are efficient as sports and wildlife photography cameras.  

The Nikon D310 can still capture sports and wildlife images with its maximum shutter speed of 1/4000s. However, it won’t capture them as fast you might desire.
Same as Nikon D3100
No Focus Peaking The focus peaking camera is used to highlight what is in focus within the frame.  

The D3100 cannot do this as this feature is missing.
Same as Nikon D3100
No Panorama Using the panorama feature, you can stitch several pictures together to form a single panoramic photo.  

The Nikon D3100 does not have the panorama feature.
Same as Nikon D3100
Lacks NFC The NFC (Near Field Communication) makes pairing with smartphones easier.  

This feature, which in most is used with the Wi-Fi feature can also be used to sync cameras with mobile phones to facilitate file transfers.  

The NFC feature is missing in the D3100.
Same as Nikon D3100
Absent Built-in Bluetooth Another wireless connection feature which is absent in the Nikon D3100 is the Bluetooth.  

The Bluetooth feature is not strange to us as we’ve used it for wireless connection with our mobile phones.
