I wrote about this in December. It really appears to be specific to the FE 35mm f/2.8. I haven't really seen it with the other lenses (and I've looked). You do have to work pretty hard to see it. Overall, Lloyd is a cranky blowhard but this appears to be real.

From time to time, I point my camera at the right things. This is generally when I forget everything I've learned.
