Design

1.Has a flip-out screen
Sony SLT-A77 II
Sony SLT-A99
Flip-out screens can be useful for tricky shots.
2.weather-sealed (splashproof)
Sony SLT-A77 II
Sony SLT-A99
The device is protected with extra seals to prevent failures caused by dust, raindrops, and water splashes.
3.Has a built-in focus motor
Sony SLT-A77 II
Sony SLT-A99
The focus motor moves the lens in order to autofocus. For system cameras, having a focus motor in the camera's body allows you to use a wide range of lenses, including lenses which do not have their own focus motor. For compact cameras, a focus motor is usually built-in.
4.weight

647g

812g

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.
6.has an optical viewfinder
Sony SLT-A77 II
Sony SLT-A99
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.

Optics

1.sensor size

23.5 x 15.6mm

35.8 x 23.8mm

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

51200 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.
Fast continuous shooting is useful for catching action shots.
6.has AF tracking
Sony SLT-A77 II
Sony SLT-A99
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 60fps

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.
When recording movies they stay focussed and sharp.
3.has a 24p cinema mode
Sony SLT-A77 II
Sony SLT-A99
24p is a video format (24 frames per second) traditionally used in cinema. Nowadays, it is used to create film-like motion characteristics.
4.supports AVCHD format
Sony SLT-A77 II
Sony SLT-A99
AVCHD (Advanced Video Coding High Definition) is a file-based format for the digital recording and playback of high-definition video. It's a standard popular among professional cameras and camcorders.

Audio

1.has a stereo microphone
Sony SLT-A77 II
Sony SLT-A99
A stereo microphone allows to record audio files or movies in stereo without an external microphone.
2.has a microphone input
Sony SLT-A77 II
Sony SLT-A99
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)

480shots

500shots

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