Design
The device is protected with extra seals to prevent failures caused by dust, raindrops, and water splashes.
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.
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.
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.
A hot shoe can be used to attach an external flash, as well as light meters, viewfinders, rangefinders and other attachments.
Optics
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.
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.
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
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.
24p is a video format (24 frames per second) traditionally used in cinema. Nowadays, it is used to create film-like motion characteristics.
Audio
More microphones result in better sound quality and enable the device to filter out background noise.
Battery
CIPA is an independent, standard measurement that determines how many shots a camera can take before the battery dies.
The battery is removable and can be replaced by the user if broken.
The battery can be recharged and used over again.
An indicator shows you when the device has low battery.
Battery power, or battery capacity, represents the amount of electrical energy that a battery can store. More battery power can be an indication of longer battery life.
Features
The maximum ISO at which the device still captures excellent quality images. Source: DxOMark.
The device can connect to Wi-Fi.
A device's overall image quality score considers: color depth, dynamic range and low light performance. Source: DxOMark.
The better a device's color depth the more color nuances it can distinguish. Source: DxOMark.
A remote control allows you to control the device remotely. The remote control can be included or optional.
The better the dynamic range the system captures a wider number of values from dark to light leading to more details in low and highlights. Source: DxOMark.
