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.

CMOS image sensors are slowly replacing CCD sensors, due to reduced power consumption and better image quality. They can be very compact and cost relatively little to produce.

With manual white balance you can choose the most accurate setting and avoid the green, blue or red hue which can occur in auto mode. You can also change the setting for artistic effect.

This allows to manually set the ISO level.

A BSI (backside illuminated) sensor is a camera image sensor which captures better quality images in poor lighting conditions, and offers better overall sharpness and image quality.

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

A stereo microphone allows to record audio files or movies in stereo without an external microphone.

Zoom microphones record very high quality audio, and enable you to record sound from a distance. This can be useful for recording meetings, lectures and presentations.

More microphones result in better sound quality and enable the device to filter out background noise.

Best

With a standard mini jack socket, you can use the device with most headphones.

Devices with stereo speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better experience.

NFC (near field communication) allows a device to perform simple wireless transactions.

The device comes with a built-in USB male connector and doesn't need a separate USB cable to connect with the computer.

Newer USB versions are faster and have better power management.

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.

An indicator shows you when the device has low battery.

A hot shoe can be used to attach an external flash, as well as light meters, viewfinders, rangefinders and other attachments.
