Losing Focus on Images Hello. I've a problem when trying to photograph a single/couple/group - full length. If I use my center focus point and lock on someone and recompose, I find many of my images are "soft" (even if I swap to one of my other focus points) If I'm doing head-and-shoulders or half body, it doesn't seem to be a problem. I'm sure it's user error and not equipment! I'm shooting with a 5D MkII and all pro lenses. Someone told me she focuses on 1 person, then ZOOMS OUT, while keeping the focus locked.... what's the correct thing to do here ? Thanks

Hi Robyn, What aperture are you using ? I think you have to think along the lines of depth of field and the shooting plane. Keep the camera square with the plane. I would try f/9 or f/11 and see if this makes a difference. Also, each lens has its own character such as my 24-70 creates about the same effect when shooting at f/4 as my 100-400 when shooting at f/7.1 in that the subject will be sharp but the background (at 8 to 10 ft behind the subject) will be nicely blurred. With large groups, the plane has more variables as far as focusing and using f/16 or f/18 usually works but often times this means adjusting the ISO as well. Great thing about the 5D2 is even shooting at ISO1600, the images are not noisy. Hope this helps, Carlton

Hi Robyn, That's good advice from Carlton. Just to make sure: Are you using "One Shot AF"? If you are using "Servo AF" the camera will refocus when you recompose your image. Greetings, Rainer
