Design
Flip-out screens can be useful for tricky shots.
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.
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.
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.
Slow-motion is an artistic video effect that makes time seem to go slower. It is achieved by recording a video at a higher frame-rate than the standard playback rate of 24fps or 30fps. Frame rates for slow-motion videos vary between 60fps and 960fps.
AVCHD (Advanced Video Coding High Definition) is a file-based format for the digital recording and playback of high-definition video. It's a standard popular among professional cameras and camcorders.
Audio
A stereo microphone allows to record audio files or movies in stereo without an external microphone.
A microphone port allows connecting external high-end or specialized microphones.
With a standard mini jack socket, you can use the device with most headphones.
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.
Features
The device can connect to Wi-Fi.
A remote control allows you to control the device remotely. The remote control can be included or optional.
The device has a standard memory slot (such as an SD or micro SD card slot) that enables you to extend the built-in internal storage with affordable memory modules, or easily retrieve data, such as photographs, from the memory card.
Wi-Fi 4 (802.11n) is a wireless standard released in 2009. It has faster transfer rates and improved security compared to its predecessors – a, b, and g.
Devices with a HDMI or mini HDMI port can transfer high definition video and audio to a display.
This technology allows the users to use their smartphone as a remote control for the device.
