Since the new Canon 5D Mark IV and 1DX Mark II uses an incredible amount of data for 4K I decided to purchase the Sandisk 256gb CF card. This card allows me to shoot 1 hour of beautiful Canon 4K and with the reliability of Sandisk your can't go wrong.

Has been working for a year and a half in a D800 without any problems. Reliable and -really- fast card (I hardly do any video). It is used in duo with a SanDisk SDHC Extreme PLUS UHS-1 U3 V30 32GB memory card.

The additional super-large capacity of this CF card will be essential for HD movies with my new Canon 5D Mark IV. I've only had the device for a week, but as every SanDisk card I've ever owned still functions perfectly, I expect this one to be very reliable too.

I have always had great luck with the SanDisk Extreme Pro cards. Being a primarily high school senior photographer, this 64GB is the perfect size for capturing a full session with my D810.

I use this mostly with a Canon 7DII for bird photography, and occasionally take short videos. It has sufficient capacity to hold several days' shooting, so it's great for being out in the field without download capability. I have three that I use for long trips.

The card is of good quality. But before buying it, check the compatibility of your device, see the update of your firmware... Example, the card works on a NIKON D3 but will not work on a NIKON D300 despite a last update. So the small advice, check of the compatibility.

I have used various brands of CF and SD cards since 2002. SanDisk has never let me down so far, whereas other brands I've purchased have failed (although it has been rare). Whether a novice, a professional or somewhere in between, you are completely dependent on your memory cards and expect them to...

This card is extremely fast, which is especially important when shooting video in higher speeds and when taking action shots of sport events and wildlife. I have a Canon 7D Mk II and this card will let me utilize the highest settings for videos. Playback is very smooth.

I have never had any issue with any SanDisk cards. I have purchased a couple dozen SanDisk Cards so far. I am using these in a Canon 7D Mark II. I have them configured to write the raw file to the CF and jpeg to the SD card. They are one of the fastest cards for the 7DII.

I popped it in my 5D Mark III along with my SanDisk 64GB SD card (which I am going to make my back up as I shoot simultaneously) and set the capture to RAW (CF) + JPEG (SD) and I can just tell that the speed makes a difference. I am just assuming at this point that this is going to last forever.
