Sometimes twice as much really is twice as good. Compared with the high-end Nikon DSLRs before them, the first mirrorless Z6 and Z7 cameras were criticized for only having a single memory card slot. That removed the safety net of being able to create instant backups on a second memory card every time you press the shutter button – as well as denying a whole lot of other options we’ll come to later.
Another problem for many of us was that the single slot of these cameras only took the relatively uncommon XQD memory card type, which are comparatively expensive to buy and completely different to the SD (SecureDigital) cards most of us have amassed. Fortunately, the Mark II editions of these cameras fell into line with the majority of other high-end Nikon DSLRs and subsequent mirrorless cameras by featuring dual memory card slots, including an SD slot, which enable you to enjoy a wealth of useful functions.
