I agree with everything mentioned here, however I came across this item a couple of years ago, but I can't guarantee positive results since I've luckily never had a problem with a card. I hope it helps. Ed
Personally, I'd love to have the Nikon D810, but only if I could put my Canon glass on it! Nikon doesn't make the high quality glass that I need, for the lenses that I use. For example: Canon TSE 24mm mark2.
