Lexar Professional 800x 64GB CompactFlash Card LCF64GCRBNA8002 - 2 Pack

Works great with 5DMKII. When i received these in the mail i wanted to test these out right away to make sure they worked on my camera. It's my first time shooting with this brand as I am used to shooting with SanDisk Extreme Pro series at 160/mbs. Which is equivalent to lexar's 1066x. But I decided to try the 800x to see if it makes the difference and increase the gb while I am at it. Didn't notice a difference at all. I shot the way I normally shoot which is a RAW w/large jpg. The data writing to the card was extremely fast and didn't lag at all. I just kept shooting to see if it will buffer out at my normal pace and sped up a little bit. For a card going 120/mbs comparing to 160/mbs. I couldn't feel a difference on the 5DMKII. I can't say for other cameras though, the newer models could be different.Performance so far on my testing has been amazing. Reliability, only time can tell. I'll update if i have any issues.Update: 4-4-2016: It's almost been a year with using these cards and it's still perfect. No issues reading or writing on my 5DMKII. HIGHLY recommended.

Not much to say, but I needed a pair of 64gb CF cards and the price was good on these guys and Lexar is a good company, so I picked them up. I'm not going to get technical, but when I upgraded form a Canon 7d to a 7d Mk II it was obvious that my old cards just weren't going to keep up with the camera. I use these in parallel with a pair of 64gb SD cards from Lexar in both of my cameras and I haven't had any issues so far after 3 weddings. CF cards seem to be on their way out, but while I need them I'm sticking with these guys and will probably buy 1 more pair to have a back-up set.

I would put zero stars if I could.I have two Nikon DSLRs - Nikon D200, Nikon D300.The D300 saves bigger files so I needed CF cards with greater capacity to get the same number of shots on a card.Also, I shoot sports photography, where you shoot long bursts; you don't want to be changing cards if you can help it.When I tried formatting the cards (2-pack) in either camera, they came up as FULL. No shots available.I called Lexar asking if there was a compatibility problem with these (older) cameras. They asked me to return them and they'd check them out.No answer about compatibility, just returned cards.Still don't work.So I'd like to exchange them for equivalent cards of, say, 16GB per card, because I know 16GB cards work in these cameras.BUT... I am now outside the return/exchange window on Amazon.So I'm out $100 for cards that Amazon won't return/exchange, and Lexar apparently thinks are OK.So much for getting a deal on the two-pack of high-capacity cards.Not happy.And disappointed, because this is the first time Amazon has ever failed me.

Bought this card for my Canon EOS 350D camera. This brand is the only one I use and I always seem to get a great price for them here. I'm always afraid to delete pictures from the card after I transfer, so instead I just buy more cards! Can't go wrong with this!

So far, so good. I got this when I pulled my old Canon Rebel XT SLR out of storage. It can only hold a few hundred pics and I needed an extra card. I'm using it on a Mediterranean cruise, so I'll be back if it doesn't work!

Lexar CF cards are the only brand I use. I have tried another popular brand and had problems after only a few uses. From then on I have only used Lexar.

DO NOT purchase 32gb cards from Lexar. We had 4 cards fail all within the last year. They were all Lexar 32gb.

One of the best cards I have bought I have only been doing small projects but lately took on larger projects and had plenty of room to spare on this card after filming for a bit uploads fast onto my Mac as well.

Bought komputer bay 32 gb 1000x udma7 for my 5dmark 2. Did'nt check it and went to overseas for my nephew wedding and while taking pictures found out it card was full with around 200 pic. Later found out that card space showing only 7.38 gb capacity. It was full no other card available my wedding photo shoot was cut half. Came back to Canada, return the krompton bay cf card back to Amazon with full rebate.Then i ordered Lexar 32 gb 800x udma7 dual pack for $120 cad. Card delivered within few days. Immediately popped into my 5d mark2 and showed 32 gb, tested for both cards, both were fine and showing 30.2 gb capacity.Started taking pic and worked fine,no problem since 4 weeks, i would recommend lexar 800x 32 gb.No more buying cheaper krompton bay cf card .

The compact flash cards I own. Very fast and durable. You can't go wrong with Lexar.

Product exactly as advertised.......received exactly when it was to be received.
