Currently I'm using all Lexar Professional cards (both SD and CF), and have had a few not so pleasant experiences and wanted to know if anyone has encountered something/anything similar.
In my 5DIII, I've got a 64GB 1066x CF card and 32GB SD card (I can't remember the speed). I have raw files being shot to the CF card and large jpegs to the SD card. All day long no issues; hundreds of images shot. Then about halfway through the reception, bam, I press the shutter button and the shutter opens, but never closes. The red light just stays on until I shut off the camera, at which the top lcd flashes (way too quickly I might add) a Card 12 Error (I think it is 12 anyway). When I turn the camera back on, it works fine for a while, but then will do it again. I'm totally puzzled how the setup will work fine all day long and it is only when I get to a certain point that it craps out. Anyone have anything similar happen? Were you able to resolve your situation?
I'm thinking that there is a corrupt part of the card and when the camera gets to the point where it needs to write to that sector, it gives the error message (although at this point I don't know if it is the CF or SD card).
The problem is in recreating the error. I can't do it intentionally; it kind of just happens. I'm going to order some new cards of a different brand (i.e. Sandisk) and see what happens.
Does Lexar still honor the warranties on their cards?
