This is to be my rodeo and soccer photographing lens, but it also makes great portraits.
Heft: This lens is big and solid. Nobody will mistake your camera for a point-and-shoot when you have this lens mounted; especially with the hood which sticks out another 4 or 5 inches. I use the tripod foot as a handle, resting it on my hand when shooting since that is the center of balance of the whole system. It is also a handy way to pick it up knowing you aren’t going to drop your 0 lens because your hand can’t quite wrap around this huge lens. This is an ACTION lens, I might not ever put it on a tripod.
VR: Don’t need it, don’t want it on a action photography lens. Because of its mass and balance, it *eats* vibrations.
Focusing: Fast and spot-on. Not quite as fast or as silent as Nikon’s 24-70mm F2.8.
Manual focus is very elegant: The very wide focus ring near the end of the lens (away from the mount) *snaps* forward and backward about 1/4 inch to engage the manual versus automatic. For instance, I saw a chipmunk visible through a thicket of sage. The camera wanted to focus on the sage. So, without even taking my eye off the viewfinder, pull the focus ring slightly toward myself and feel the slight “snap” of engagement, turn the ring (a small turn produces large changes), and get a shot of the chipmunk. To be sure, almost all modern lenses can override the automatic, but they immediately try to refocus on the wrong thing. This one goes into true manual focus and stays there without ever touching the camera or taking your eye off the target, or locating and changing switches on the lens or camera.
Sharpness: Almost perfect. The only lens I have better is the Nikkor 24-70mm F2.8. I noticed ever so slight softness at edges, maybe as much as 2 pixels, but the scene was very demanding and very likely the filter on the lens contributed to that off-axis softness.
Light fall-off (uniformity of illumination). Nearly perfect illumination edge to edge. Hugin’s auto-vignetting corrector shows that it has a barely detectable light fall-off of around 2 percent or so. When used wide open at its wide angle setting, you will notice some corner darkening of about 10 percent, part of that was doubtless the UV filter. This is an extreme operating condition and is correctable in the computer in those cases where it is important.
Flare and other abberations: It shoots into the light reasonably well. Chromatic abberation is essentially undetectable. Barrel and pincushion exist in the usual places (barrel at wide angle, pincushion at telephoto) but is close to negligible.
