Sony Cyber-Shot DSC-RX100 mark VII

The size of the digital camera screen used for searching images, viewing and editing taken photos. A bigger display is convenient at use, however, it has to be taken into account that the bigger the display the shorter the battery life of the camera. If the battery life time is more important than the viewing convenience we recommend to buy a camera with a smaller display and a separate image searcher.

The power supply source of a digital camera can be both batteries or accumulator. The advantage of batteries is that they are widely available in stores and the advantage of the accumulator is that it can be charged and used without the need to buy an extra battery. Prior to buying a digital camera you should verify whether its power supply complies with your needs.

The matrix resolution of a digital camera determines the amount of information that the camera can "record" within a single photo. A higher index of resolution means a more detailed image and a higher quality of the image. Cameras with higher resolution require more space on the memory card for storing their photos, therefore we recommend to buy a corresponding capacity memory card with a high resolution camera, for example, a 2Gb card for 8Mpix camera.

Optical zoom or zooming-in by means of the optical devices is an important index for taking photos of remote items. For close-ups 3x optical zoom is sufficient, for taking photos of more remote items this index has to be higher.

The type of the memory card that can be placed in the digital camera for increasing the space for storing photos. When you buy a photo camera you should take into account that one or two types of memory cards are compatible with each camera. SD (Secure Digital) and CF (Compact Flash) are the most popular formats of memory cards.
