Sony 64GB SDXC Secure Digital Flash Memory Card - EXTRA PROfessional Series Class 10 UHS-II/U3 (Read 260MB/s Write 100MB/s) - SF64M, SF-M64/T

Nice and fast reliable SD card. Currently using this on a Sony A7 III. Provides great write speeds, I can shoot 60 RAW shots before the buffer fills and it clears to the card nice and quickly. Read speeds also excellent when downloading to computer.

I needed a back up for the Sony tough and this was cheaper and very similar.

Useful saving on some other brands, and speed is more than adequate for highest quality full frame video.Another make - which may be the market leader - started to physically break apart in my RX100V after being taken in and out frequently, and can no longer be used.So paying their premium didn't pay off.

This seems like a good card so far. I am currently using with my gh5 and I wanted a card with excellent reliability for a professional job. It worked well but they are on the pricey side. Still the piece of mind is worth it.Overall.+ Seem reliable+ Fast write speed- expensive

Received tried out worked fine on camera, but Mac would not read card. Contacted Supplier advised to return and replacement on the way, received new card in couple of days and worked with no problems at all. The original card must have had a fault, not suppliers fault, but excellent service, thank you

Great card! Really fast write and read speeds I've tested and used this card for the last couple months on the GH5 - it records in all the resolutions without any issues (haven't tested C4K full quality for extended periods of time but it lasted 5mins without stopping)

-There is no lag on HD/4K video, quality doesnt decrease.-Over 2hours of 4K video recording can be done with this size memory card, 3-4hours of Full HD.-Works on my laptop and Sony Ax33 Videocamera.

I have always used this SDXC and I would use no other....they are excellent and never let me down
