Sony80GB TOUGH CFexpress Type A Flash Memory Card - VPG400 High Speed G Series with Video Performance Guarantee (Read 800MB/s and Write 700MB/s) – CEA-G80T

very fast card, absolutely needed if you do sport photography etc, zero buffering. works perfectly fine with my Sony a7IV

One of the best in his category. Never had issue with it for the last two years.

Great card, super fast - just on the expensive side

Works well, but soooo expensive

I use this with a Sony A7 IV. It improves battery life by being more efficient than an SD card. The speed is incredible, you really can just continuously shoot.An expensive but worthwhile upgrade to an SD equivalent.

Super fastThese small memory cards are perfect for the Sony A7SiiiTested on a few weddings recording the highest quality video footage with ease

A UHS-II V90 SDXC memory card will do the job if you're just wanting to take RAW photos or record in 1080p; however, you may find when trying to record 4K video, your camera may not allow you due to the lack of write speed, this is where the CFexpress Type A card comes in handy.With a write speed of up to 700MB/s, you shouldn't run into issues when recording highly demanding video files or shooting continuous in RAW; this card is blazingly fast!The downside is the price, which upset my wallet quite a bit and furthermore, the Sony CFexpress Type A Reader is also eye-wateringly expensive if you want an alternative to your cameras USB port to transfer the files.If you have a camera that is compatible with both, UHS-II SDXC and CFexpress cards (such as the Sony A7IV) and are pondering which one to go for, I'd say futureproof yourself and get this card.

Nice slick bit hunk of metal from Sony. Gives much quicker card copy times than using the USB-C output from the camera - worth the money to save the time if you're working on quick turnaround jobs!
