SanDisk - Extreme Pro 32GB CompactFlash (CF) Memory Card

Recently purchased A used Canon EOS 7D and wanted a Compact Flash Card that could be written to very quickly to lessen Buffer choke when in continous shooting mode (up to 8 shots per sec.) card has more then met The Canon Specifications

As a photographer I need reliable and efficient tools for the job, this card does that... I inadvertently left this card in my pant pocket after a photo shoot, went through a wash cycle and stll works without a problem! Highly recommend. .

I use this with a startech adaptor to use it as a hard drive in an older windows 98 machine, and it works flawlessly. Faster than the ATA 133 spec so its as fast as it can get, windows seemingly boots up instantly.

I purchased these for use in my new Canon 7D MKII. It easily keeps up with the camera, allowing me to shoot many continuous shots. I have yet to reach the point where I have to stop taking pics and wait on the card to "catch up". The one drawback is that the card readers in my computers would not read this UDMA7 card. I had to do some investigation on the 'net and ended up purchasing external readers that connect to a USB 3 port. They cost a little more than those that won't read UDMA7 cards but are very much worth it. YOU NEED TO BE AWARE OF THIS BEFORE PURCHASE.

I'm using this card in my Canon EOS 7D Mark 2, and in my EOS 7D, and this card is fast enough to handle the fast burst rates that these cameras shoot (and I shoot both Large RAW and Large JPG simultaneously so fast storage is critical to me). These cards have never failed on me (I have a number of the SanDisk Extreme CF cards) and I've been using them for years. I HIGHLY recommend them.

These are hard to come by now. Works great with my camera and is very fast.

Well, since I upgraded to the new canon 5d MK IV, I realize I needed bigger and faster cards and specially for video recording. The cards son far feel great. It handles files quickly and can review my shots quicker. I like shooting fast for my lifestyle photos and this CF cards deliver as advertise. They also work great with my medium format camera. I can now shoot a bit faster with out being delay or getting and error on the digital back on my cf card. I would be buying more cards.

Purchased the SanDisk Extreme Pro CF card (32GB size) about six weeks ago and have used it almost daily in a Nikon D4S without any issues. Fast writing speeds and no technical problems to report. When uploading to laptops and desktops using a USB 3-type card reader and cable the typical upload speeds have been between 120-128 MB/S. Recommend buying if found at reasonable price.
