24-70 L

Any users using this lense, the only problem i face when i turn it to 24mm for group picture tend to have back focusing problem. By the way am using a 5D for all my assignment, din try it on 20D though.

I've had the brick for a couple of years now and no problems with back focussing anymore within the zoom range. Mine is tack sharp and accurate.

Forgot to mention, I have used it on the 1D2 & 3 and also the 40D.

The 24-70 i own got no problem after 28mm. Still my choice for event shoot. Just dun understand why it got back focus for grp shot only.Sometimes i use 24mm prime to shoot night wedding table picture, it come out nicely.
