I think i may be having a similar issue. It 100% could be user error. I love this lens so I'm fairly careful with it. The hazy look started. I'm thinking it may be the lens, because i don't have this issue with any of the others. It's hazy while using the viewfinder. However, in most cases the picture actually comes out clear. I've changed from manual to auto and also adjusted aperture and shutter. It has cleared up a bit, but it's not as clear as it used to be. Also, I just got it at the beginning of December. I have the R8.
