Top specs and features


1.has a flip-out screen
Sony Alpha a9

Flip-out screens are useful for doing tricky shots.

For example

Canon PowerShot SX70 HS

2.Weather sealed
Sony Alpha a9

Device is protected with extra seals to prevent failures due to any kind of weather.

3.Is dustproof and water resistant
Sony Alpha a9

Dustproof/water resistant at depth equal to or greater than 1 meter.

For example

Panasonic Lumix DC-TS7

4.has an optical viewfinder
Sony Alpha a9

An optical viewfinder (or OVF) allows the photographer to compose a shot while seeing exactly what the lens sees. There is no time lag and they require no power - as opposed to electronic viewfinders which can drain battery life. They are also better in low light situations.

For example

Leica D-Lux 7

5. more viewfinder coverage


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 afterwards to get them looking perfect.

6.Has a built-in focus motor
Sony Alpha a9

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.


1.sensor size

35.6 x 23.8mm

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


Polaroid Snap

81.2 x 25.4mm

2.focus points


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.


Canon EOS R


3.has AF tracking
Sony Alpha a9

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.

4.maximum light sensitivity

204800 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.
