I have a 7D which doesn't seem to be focusing properly and I would like to know from others who had "focus issues":
1) were you able to get the AF repaired to work properly and if so what did the repair center say?
The reason I ask this is that I have been traveling in Asia and Finally I was able to get to Bangkok to get my camera looked at. I told them the problem I was having: soft, oof and front focus/back focus problems with my L series lenses. I showed them examples of the problem. They checked the AF twice and said there were no problems. I had to leave Thailand but the problem continued. Finally I got so fed up of looking at a portfolio of soft shots - (granted there are some sharp shots but very few unless I am looking at shots from my 40D which are sharp) so I returned to Thailand from Laos to get the camera "fixed". I had written Canon US tech support twice explaining my problem and they told me they had never heard of such a problem.
I would like to be able to make sure I know what tests should be done to test the AF system in order to ensure that these tests are being performed when I take my camera to get repaired next Monday, April 19th. All I was told by Canon Thailand was that they tested the AF system on the computer and all was well.
I use single shot AF mode, with a single auto focus or spot focus point, usually the center one. At times it seems like the AF system is picking up the highest contrast area surrounding the selected AF point (again, I am using single AF mode, not expanded). I shoot a lot of portraits and environmental portraits. If I take a fairly close portrait I can get a sharp (but usually not tack sharp compared to my 40) shot. If I take an environmental portrait (the single focus point on the face of the subject) this is where the problems really start - back focus (focuses on a high contrast object behind the subject) , front focus (focuses on a high contrast object in front the subject), soft focus. By the way I shoot in RAW and process using Lightroom 2.6
Any input will greatly appreciated
