Ever since receiving my 70-300, I've found the sharpness to be wildly inconsistent and rather disappointing. Even when shooting in broad daylight and at a high shutter speed I've found what appears to be smearing and refraction like rendering. I've attached a screenshot of just a recent image taken out at the beach, it's at 100% zoom. I'm trying to figure out if perhaps I have a bad copy of the lens, shooting wrong, etc. Thanks for the help.
