I just bought a used D850 DSLR camera, any recommendations on which memory card should I get ?
I highly recommend using CFexpress Type-B cards for optimal performance. The camera has dual card slots - one CFexpress Type-B/XQD and one SD UHS-II. While you can use SD cards, CFexpress Type-B offers faster write speeds which is crucial for buffer clearing, especially when shooting in burst mode or recording 4K video. I personally use Lexar CFexpress Type-B Gold Series and they've been fantastic.
For the D850, definitely go with CFexpress Type B cards if you can afford them.
Any CFexpress Type-B cards are OK, I personally love the Angelbird.
Good to know!
CFexpress Type-B card is the best choice for Nikon D850, for example, Lexar Professional Silver SE CFexpress Type B is a good choice.
