See you just have to have faith in Canon L lens :D :D :cool:

Roy just out of interest try that shot again on a rock solid support and very ginger on the shutter release.

Or use the timer to reduce camera shake.

Rob, used tripod + remote release for this one. Looks about the same has the hand held. Must say that my tripod and head are not the best - notice the lens bouncing as the shutter fired.

It looks like a spot of movement on it still. Have you got a heavy cushion you could as a damper ? stick on top of the lens.

Looks like next project could be a better tripod ? :D

Notice the fun we can have spending somebody elses money :rolleyes:

Given that Roy has said he can see the end of the lens bouncing as the shutter fires I think that is fairly damning evidence of the problem, camera shake, not a faulty lens.

I've just noticed that we are looking at a medium quality jpeg so the original before crop maybe better than we think.

Went out this afternoon - fantastic light. Took 40 or so shots all at ISO 400 and speeds of between 1/1000 and 1/2500 (handheld at f5.6) The attached was about the best of the bunch.Most of the shots were still soft

Can you explain what's going on with the out of focus area behind the gull. It appears to have some sort of diagonal banding/streaking. This area also seems to have quite a few jpeg artefacts and noise creeping in too. What sort of post processing have you given the shot?

Coverted to TIFF. A bit of a 'Shadows and highlights' tweak - resize -plus a touch of smart sharpen -, and then save as to med jpeg.
