I have always shot in raw and still do. The last 2 times I've taken pictures, lightroom won't allow me to import my files off of my compact flash. It says it dosen't support my file type? I thought it was a corrupted card so I tried a second one and it gave me the same results. Any ideas what's going on?
O.K. so what it actually says is "the following files can not be imported because they can't be read" Then it lists the CR2 files. I am using the same camera, however I recently set it back to the default settings. Its a Canon 50D. It seems like the problem started when I did that. Not sure what's wrong but I need to check into my camera too. It will no longer go below 200 ISO annoying since I prefer 100.
If I'm not mistaken, once you turn on Auto Lightning Optimizer or Highlight Tone Priority, it will not let you go under ISO 200. I forgot which one, but definately one of them will limit your lowest ISO to be 200.
