Flip-out screens are useful for doing tricky shots.
Canon PowerShot SX70 HS
Device is protected with extra seals to prevent failures due to any kind of weather.
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.
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.
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.
23.6 x 15.8mm
The larger the sensor the more light the sensor captures yielding in better image quality.
81.2 x 25.4mm
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
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.
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.
Nikon D7500 + Nikon AF-S DX Nikkor 18-140mm f/3.5-5.6G ED VR
Optical image stabilization uses gyroscopic sensors to detect the vibrations of the camera. The lens adjusts the optical path accordingly, ensuring that any type of motion blur is corrected before the sensor captures the image.
Leica D-Lux 7
When recording movies they stay focussed and sharp.
CIPA is an independent, standard measurement that determines how many shots a camera can take before the battery dies.
Samsung Galaxy NX Mirrorless + 18-55mm f/3.5-5.6
The battery is removable and can be replaced by the user if broken.
The battery can be recharged and used over again.
