Sony M Series SDXC UHS-II Card 64GB, V60, CL10, U3, Max R277MB/S, W150MB/S (SF-M64/T2), Black

This card is rated for 150 MB/s write and 277 MB/s reads. It met the write speed on the dot and the read speeds are pretty close.

no hay queja alguna. excelente producto, lectura y escritura excepcional. la uso en mi nikon D500 totalmente recomendado

Trabaja muy bien con mi Handycam!

Everything I expected.

I just ran into a problem that just popped up out of nowhere. All of a sudden Im unable to record simultaneously on my A7iii though I was able to just last week. I have 2 A7iii cameras, one with this memory card and the other has the 64gb version. Both worked in the past but today I received an error message. It wont even let me record in the non 4k mode. Very strange. The memory cards in the 2nd slots are the same for both cameras so that should not be a factor. When I switched the 64gb and 32gb memory cards, the one with the 64gb worked but not the 32gb. Can someone please explain or is this just a bad card? Like I said, it worked just last week and for previous events.

I do a lot of 4K videography and I need dependable hi speed read and write video cards and Sony cards have always come through for me

Fast, huge, capable. What more can a photog want?

I had a 32GB sd card. Not enough space. Bought this one and now I have enough space to photograph an entire wedding plus take some video

Very good

If youre looking for dependable SD cards for the GH5s high bitrates, youre in luck. I purchased 6 of these 64GB cards. I ran multiple tests on my GH5 with these cards in All-Intra/400mbps mode... ONE THING TO KEEP IN MIND: When shooting in Back Up Rec slot function mode I keep getting a message that says Backup recording requires using two identical SD Cards. I didnt work in that mode. But... I only shoot in Relay Rec mode. And no issues, no choking so far in that mode. I normally dont shoot in All-Intra/400mbps for my clients, but its good to know that these cards handle the demand if I ever needed it (i.e. for a short film, feature film, etc.). You get about 20mins on one card slot of the GH5 with these 64GB cards. So youre looking at about 40mins in total for both slots. Dont get scammed by the V90 craze! Its just a cash grab, at least for All-Intra on the GH5. Youll have plenty of breathing room when shooting at any other bitrate as well.
