[QUOTE="Horoscope Fish, post: 386189, member: 13090"] Well the first shot is nice and sharp and the shutter speed for the chosen focal length is good on the second shot so I don't think it's a shutter speed issue. It could be that your lens is simply "soft" wide open as it is on the second shot. It could be that your "crushing" the shutter button as you take the shot. Try to make sure you preeeessss the shutter, not "stab it" when you take the shot. If I were you I'd do some testing. Do a series of, say 5 or 10 shots in good, bright light at 17mm using f/5.6 of f/8 or so. Use a shutter speed of 1/250 or better if possible. Use the center-most focus point and make sure you're not crushing the shutter button when you take the shot. After you've taken these shots zoom the lens to say, 50mm or so and do another series of shots just like you just did at 17mm. Now sit down and compare them side by side: If all your shots at 17mm come out looking soft, but they all look sharp at 50mm you know the lens is soft when shooting wide.
