This card has a new icon called V30 which I have read to mean a constant bit rate of at least 30mbs but for some reason I had problems with it in my canon 80D. I would shoot a couple photos then preview them and then if I shut off the camera and turn it back on the first image would always get...

I bought this to go into my new ZTE ZMAXPRO android phone. I originally bought a slower UHS 1 Class10 SDHC Micro SD card...and initially when I was using the camera there was about a second or more delay to store the picture.

I tried on my new sony camcorder ax33 and the images are incredible. Definitely a great buy with a great price.

Got it, opened it, and stuck it in my Canon 6D Mark II, and it wouldn't read or recognize the card, the red light stayed red for a longer time than usual. I tried to go to format in the camera, and it wouldn't register, and told me to take it out and reinsert it.

Fast and stable.

What's to say? Large capacity with a name you can trust.

Typical Sandisk product. I like it.

re: Andydreads corrupt file after turning off the camera....This is really YOUR fault. Just because you can view the capture, does not mean the file has completely been written to the card. This is particularly true with RAW files.

I've been using Sandisk flash cards for 19 years, with not even one problem. No reason to think that this 128gb card will be any different. Sandisk is the best, in my opinion.
