Almost got away this weekend to go up there but still having problems with the new gear. I think it's time to box it up and send it to Canon. What I consider routine bird shots at the house feeder are just terribly soft. Seeing the same thing with both the 400 f/5.6 and the 70-200 f/2.8. This despite being tripod mounted and shooting at around f/8 with shutter speeds exceeding 1/1000th. Unless I suddenly forgot how to shoot simple bird shots I've got a problem. From the get go I thought I had a noise problem but I realize I've just been sharpening way too much trying to compensate for a focus problem of some sort.
