Question 1

What cameras are compatible with CFexpress Type B cards?

Accepted Answer

CFexpress Type B cards fit cameras with a dedicated CFexpress Type B slot. Popular examples include the Nikon Z9, Nikon Z8, Canon EOS R3, Canon EOS R5, and Sony Alpha 1. Always check your camera's manual — some bodies that originally shipped with XQD slots were updated via firmware to also accept CFexpress Type B cards.

Question 2

Is 1TB enough storage for a day of professional shooting?

Accepted Answer

For most professionals, 1TB is generous. A single card can hold thousands of compressed RAW files or several hours of high-bitrate video before you need to offload. It's especially practical for travel or event work where you want to avoid carrying multiple smaller cards.

Question 3

Why does read speed matter on a CFexpress Type B card?

Accepted Answer

A 1900MB/s read speed primarily affects how quickly you can transfer files to a computer or SSD after a shoot. Write speed (which determines how fast the camera can flush its buffer) is equally important for burst shooting — check the card's rated write speed against your camera's buffer requirements before buying.

Question 4

Do I need a special card reader for CFexpress Type B?

Accepted Answer

Yes — CFexpress Type B cards require a dedicated CFexpress Type B reader. Standard SD or XQD readers won't work. Lexar and several other brands make dedicated readers specifically for this format, so make sure whatever reader you pick is rated to handle the card's full performance.

Question 5

Is buying a used CFexpress Type B card safe?

Accepted Answer

Used memory cards are generally a sound buy when they come from a reputable source that inspects them before resale. Flash memory doesn't wear out the way mechanical drives do under normal photo/video use. Every used card on Camera-tweedehands.nl comes with a minimum 12 months warranty, so you're covered if anything unexpected turns up.

Question 6

What is the difference between CFexpress Type A and CFexpress Type B?

Accepted Answer

CFexpress Type A cards are physically smaller and use fewer PCIe lanes, making them slower and suited to mid-range bodies like the Sony Alpha 7 IV. CFexpress Type B cards use a wider PCIe interface, allowing significantly higher throughput — up to 1900MB/s read in the case of this Lexar Pro Gold — needed by high-resolution, high-frame-rate professional cameras. The slots are not interchangeable.
