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

Fast continuous shooting is useful for catching action shots.

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 phase detection autofocus is much faster than a contrast detection autofocus and allows sharper movies.

24p is a video format (24 frames per second) traditionally used in cinema. Nowadays, it is used to create film-like motion characteristics.

It can automatically shoot pictures with a higher dynamic range (HDR).

A higher screen resolution provides a sharper image, making it easier to review your photos.

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.

A microphone port allows connecting external high-end or specialized microphones.

A timelapse shows a long passage of time sped up. A series of photographs taken from the same position over a long period is joined together to create a short video. It is great way to capture things like the setting sun, or clouds moving across the sky.

The bigger the screen size is, the better the user experience.

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.

Newer image processors are better at processing multiple tasks simultaneously, and can produce higher quality images with better low-light performance and faster AF.

It has two memory card slots, allowing you to store more photos without switching cards. This is particularly useful on long shoots when you need more space.

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.

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

The device can connect to WiFi.

A faster maximum shutter speed allows taking pictures of fast moving subjects without blur.

Flash synchronization is defined as the firing of a photographic flash coinciding with the shutter admitting light to the image sensor. In general, faster flash sync speeds are better if the photographer needs to flash-fill subjects that are backlit and wants to avoid motion blur, or wants to increase depth of field by using a high aperture.

Cross-type focus points, in contrast to normal focus points, can detect both horizonal and vertical making them the most precise and reliable focus points to use.
