Design

1.Has a flip-out screen
Nikon D3100
Nikon D5100
Flip-out screens can be useful for tricky shots.
2.weather-sealed (splashproof)
Nikon D3100
Nikon D5100
The device is protected with extra seals to prevent failures caused by dust, raindrops, and water splashes.
3.weight

455g

510g

We consider a lower weight better because lighter devices are more comfortable to carry. A lower weight is also an advantage for home appliances, as it makes transportation easier, and for many other types of products.
4.viewfinder coverage

95%

95%

With 100% coverage, you can compose the image correctly when you capture the photo. With less than full coverage, you may have to crop your photos afterward to get them looking perfect.
5.has an optical viewfinder
Nikon D3100
Nikon D5100
An optical viewfinder (or OVF) allows the photographer to compose a shot while seeing exactly what the lens will capture. OVFs have no time lag and require no power - as opposed to electronic viewfinders, which can drain battery life. OVFs are also better in low light situations.
6.Has a hot shoe
Nikon D3100
Nikon D5100
A hot shoe can be used to attach an external flash, as well as light meters, viewfinders, rangefinders and other attachments.

Optics

1.sensor size

23.1 x 15.4mm

23.6 x 15.6mm

The larger the sensor the more light the sensor captures yielding in better image quality.
2.focus points

11

11

The more focus points the more flexibility in picking which part of the scene to focus on. They also give the image sensor a better probability in identifying the right area of the scene to focus on in more automatic modes.
3.megapixels (main camera)

14.8MP

16.9MP

The number of megapixels determines the resolution of the images captured with the main camera. A higher megapixel count means that the camera is capable of capturing more details. However, the megapixel count is not the only important element determining the quality of an image.
4.maximum light sensitivity

12800 ISO

25600 ISO

With a higher light sensitivity (ISO level), the sensor absorbs more light. This can be used to capture moving objects using a fast shutter speed, or to take images in low light without using a flash.
5.continuous shooting at high resolution

3fps

4fps

Fast continuous shooting is useful for catching action shots.
6.has AF tracking
Nikon D3100
Nikon D5100
With AF tracking, once you choose the subject and press the shutter release part way down, as the subject moves, the autofocus will follow it. No more out of focus shots.

Videography

1.video recording (main camera)

1080 x 24fps

1080 x 30fps

The maximum resolution available for videos shot with the main camera. Although it may be possible to choose among other frame rates, those recordings usually have lower resolutions.
2.Has phase-detection autofocus for videos
Nikon D3100
Nikon D5100
A phase-detection autofocus system is faster than a contrast detection autofocus system. Even when recording scenes with a lot of fast movements, the videos are sharp and clear.
3.has continuous autofocus when recording movies
Nikon D3100
Nikon D5100
When recording movies they stay focussed and sharp.
4.has a 24p cinema mode
Nikon D3100
Nikon D5100
24p is a video format (24 frames per second) traditionally used in cinema. Nowadays, it is used to create film-like motion characteristics.

Audio

1.has a microphone input
Nikon D3100
Nikon D5100
A microphone port allows connecting external high-end or specialized microphones.
2.number of microphones

1

1

More microphones result in better sound quality and enable the device to filter out background noise.

Battery

1.Battery life (CIPA)

550shots

660shots

CIPA is an independent, standard measurement that determines how many shots a camera can take before the battery dies.
2.has a removable battery

4.has a battery level indicator
Nikon D3100
Nikon D5100
An indicator shows you when the device has low battery.
5.battery power

1000mAh

1030mAh

Battery power, or battery capacity, represents the amount of electrical energy that a battery can store. More battery power can be an indication of longer battery life.
