    These are fairly common as far as the quality I am getting with the 7D and the 100 - 400 lens. I would say 90% - 95% of the pictures are this bad or worse.

    I went through some more shots from the same day and these shots a a little farther away then the ones posted in earlier thread and they are more acceptable for that range There isn't a lot of detail and I wouldn't expect that but they are more in focus like I use to get with my 40D. It was later in the morning and the sun would have been brighter. I really didn't do anything different with the settings. Maybe I just have to have more light when the range gets out there. These photos are heavily cropped.

    I am not crazy! Clearly there are problems with the 7D.


    I am going to try the two things mentioned to see if they help.

    The one I am using is a work camera where as my personal camera is the 20D. I have been wanting to upgrade my personal camera but I still don't have confidence in the 7D and the new 60D is not enough of an upgrade to me.

    Those don't look bad at all for being at a distance and heavily cropped. They do appear to be front focused though.

    Sorry but I don't have a clue what you are talking about. I don't have the camera here and all of these pictures have been deleted off of it if that matters. I do have them saved on the computer I am on now.

    I agree on the front focus. I have not had a chance to do the micro adjustment yet. Was going to do it on Saturday but ended up hunting snow geese. Glad I went because it was a good day. It has been cloudy out since so I will have to wait for the next sunny day.

    Here is a shot of a speck that came fly by on Saturday while snow goose hunting. I got off 10 shots of this goose and they are almost full frame with good light. This shot was the only one that it might have tried to focus on. Maybe I need to quit pixel peeping. It looks like it caught the wing tip and even that is not sharp. The other 9 pics were a total blur.
