4. continuous shooting at high resolution
Fast continuous shooting is useful for catching action shots.
Olympus OM-D E-M1 Mark II: 60fps
5. maximum light sensitivity
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.

21. optical zoom
The zoom range is the ratio between the longest and shortest focal lengths. A higher zoom range means that the lens is more versatile.
Nikon Coolpix P900: 83.3x
22. widest aperture
With a wider aperture the sensor can capture more light, helping to avoid blur by enabling a faster shutter speed. It also provides a shallow depth of field, allowing you to blur the background to focus attention on the subject.
Ricoh GR II: f/1
23. number of microphones
More microphones result in better sound quality and enable the device to filter out background noise.
Canon EOS M50: 2
24. exposure time
When the camera shutter is open for a long time, more light is absorbed by the sensor. You can use this slow shutter speed to produce vivid night time photography, or capture the trajectory of moving objects such as motorway traffic.
Hasselblad H5D-50c: 720s
A bigger variety of brand lenses means that you have more options and can find one that suits your needs.
