#5. "RE: A possible bug with Nikon cameras with dual card slots...." In response to In response to 3
The slow down happens during normal shooting in a single shot mode or any other mode, it does not matter. It could happen if I take a single shot or a small burst. I don't shoot in more than 2 fps. And it happens randomly. Even then it slow writing I can take more pictures at normal speed. The only problem is that I have to wait 15 seconds to review the image. I shoot only in RAW, no Jpgs.
