A little while ago I bough a Canon 70-300mm on the advice of people on here.
Now I'm beginning to wonder if I bought a dud as I cant seem to get anything sharp at 300mm, but it seems very sharp at 70mm.
Alternatively (even probably) it could be poor technique or bad choice of settings.
I assume the IS is working as I can hear it whirring away. But at the minute, there's not a lot in it in terms of sharpness from shooting at 70mm and cropping in or shooting at 300mm.
So my question is what COULD I be doing wrong and how would I correct it? I haven't done an exhaustive test, so it may work on a tripod for example, but if I can't rectify this, there's not much point in having a zoom at all.
Couple of sample images...(all SOOC - just converted to JPEGS in Photoshop).
