Cameras with 2 memory cards

2 memory card slots

— the presence of two slots for memory cards in the design of the camera. At the same time, slots can differ according to the type of cards used: for example, the main slot for a fast and reliable XQD card can be supplemented by a slot for a slower, but inexpensive SD card.

Anyway, in digital cameras there are three main formats for working with two cards:

— Backup: information from the main card is duplicated on the second one. Thus, if one of the media fails, the data will not be lost.
— Recording on overflow: recording on the additional card starts when the main one runs out of space. This mode allows you to increase the total amount of available memory.
— RAW/JPEG separation: when shooting in two formats, RAW sources are saved on the main card (usually faster), and finished JPEGs are saved on the secondary one.


The specific functionality in different camera models may be different, but it is not uncommon to find support for all the described methods of operation at once. On the other hand, an additional slot affects the dimensions and price of the device, despite the fact that it is not critical for amateur filming. Therefore, this feature is found mainly in professional-level devices.
