Summary: Received and both units said card err in my cameras. Called Kingston and sent back the two cards and they over nighted me new ones with a new build that should work with my cameras. Both cards now could be formatted and I went out shooting where the card in the d4 now seemed slow and when I downloaded the pics they were corrupted in multiple ways at a rate of about 1 out of 3 I have now sent that one back at a cost of $7 twice the cards are getting more expensive due to...
Summary: I had previously purchased two of the slower 266X versions of Kingston's 16GB compact flash line which would give me errors when trying to record video using the Canon 7D. This card has been working great so far with the 7D video (set at maximum fps/quality) so far with no buffer problems or recording errors.
Summary: Compared to the xD cards i normally use this thing was sufficiently fast and allowed me over 1500 pictures in raw format on a 10 megapixel SLR camera with room to spare. Will enjoy this flash card for many years to come.
Summary: I used it the first time for a trip to the Rocky Mountains. Back at home I wanted to put the photos on my computer but it says that I have to re-formate the memory card. I'll probably lose all my photos from this trip, it's really sad. So I wouldn't recommend the memory card to anybody.
Summary: I bought this for my Silk Road tour in Jun. I used it with my Canon EOS 7D - mainly for photos, not videos. Every night I downloaded the photos to my netbook. In each download, I noticed some failed photos, 2 to 3 in a batch of 300. So the failure rate was about 1%. Then the card crashed on 15 Jun when I visited the Museum of Qin terra-cotta warriors. At that time, my camera was loaded with pictures of the Huaqing Palace and Pit 1 of the museum.
Summary: Have these cards for well over a year now. I am very happy with them. I shoot wedding photos. These cards have served me well. I am not much of a burst mode fps seconds shooter although when required I have done that. Works well with my 5D Mk II and 7D and 1D Mk II. Transfer to computer is fairly fast. Not really in secs and numbers guy.
