I just got one and love it, but noticed some shots not having that pop that I see in photos by others using that lens. I need to experiment and have only shot at f/4 so far.

Thanks. I'm sure you're right about the post-work. I've had the lens for just a couple of days and most of my shots were hand-held at 200mm. I'm very impressed with how it handles, just looking to improve

I would suggest a tripod...even that much is going to make your picture sharper. Canon 6D, & Sony α6000

As someone else said, you need to make sure you've got a fast enough shutter speed if you're going to shoot it that way though. 7D, BG-E7, BGE2x2 (both FS), 17-55 f/2.8 IS, 17-85 f/4-5.6 IS (FS), 50 f/1.8, 85 f/1.8, 70-200 f/2.8L IS Mk I, 70-300 f/4-5.6L, 550EX, Kenko Pro300 1.4xTC

RPCrowe Cream of the Crop  More info | Both my non-IS and my present IS model are sharp wide open. However, as with any digital image, the images from these lenses benefit from post processing sharpening... See my images at http://rpcrowe.smugmug.com/

Faster than that if you're on a crop body. "I think Bigfoot is blurry, that's the problem. It's not the photographer's fault. Bigfoot is blurry.
