Re: Canon 100-400 f4-5.6L IS USM Lens
Hi - so here are a couple of examples. Firstly 'stick'. This was stuck in a lake about 20 ft in front of a bird hide at a local wildlife reserve. Selecting centre point I focussed on the very tip of it as you can see so as to be ready when a bird landed. The tip is not in focus but an area lower down is. I focussed with no tripod but the lens was supported on the edge of a bird hide. It was taken at 3200ths ISO400 f5.6. I took several stick shots and did not manage to get a single sharp one.
Duck 1 and Duck 2 were taken split seconds apart 1200ths ISO200 f5.6 with AI servo. The first is sharp - in the second the focus has moved off the duck and picked up the background even though the duck did not move.
There a plenty of other examples where I have centre point focussed bang on the target but its not sharp.
I too have the odd shot that is tack sharp, fantastic, but it seems to be a random event.
