Cheap alternatives

Design

1.weather-sealed (splashproof)
Canon EOS 550D
Nikon D3100
The device is protected with extra seals to prevent failures caused by dust, raindrops, and water splashes.
2.weight

530g

455g

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.
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.
4.has an optical viewfinder
Canon EOS 550D
Nikon D3100
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.
5.Has a hot shoe
Canon EOS 550D
Nikon D3100
A hot shoe can be used to attach an external flash, as well as light meters, viewfinders, rangefinders and other attachments.
6.resolution

1250 x 833px

588 x 392px

Resolution is an essential indicator of a screen's image quality, representing the maximum amount of pixels that can be shown on the screen. The resolution is given as a compound value, comprised of horizontal and vertical pixels.

Optics

1.sensor size

14.9 x 22.3mm

23.1 x 15.4mm

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

12800 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.
Fast continuous shooting is useful for catching action shots.
6.has AF tracking
Canon EOS 550D
Nikon D3100
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 30fps

1080 x 24fps

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.
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.
When recording movies they stay focussed and sharp.
4.has a 24p cinema mode
Canon EOS 550D
Nikon D3100
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 stereo microphone
Canon EOS 550D
Nikon D3100
A stereo microphone allows to record audio files or movies in stereo without an external microphone.
2.has a microphone input
Canon EOS 550D
Nikon D3100
A microphone port allows connecting external high-end or specialized microphones.
More microphones result in better sound quality and enable the device to filter out background noise.

Battery

1.Battery life (CIPA)

440shots

550shots

CIPA is an independent, standard measurement that determines how many shots a camera can take before the battery dies.
2.has a removable battery
Canon EOS 550D
Nikon D3100
The battery is removable and can be replaced by the user if broken.
3.has a rechargeable battery
Canon EOS 550D
Nikon D3100
The battery can be recharged and used over again.
4.has a battery level indicator
Canon EOS 550D
Nikon D3100
An indicator shows you when the device has low battery.
