8.2 Resolution 9.2 8.0 Perceived 9.1 8.1 How to interpret the test results. What my testing proceedure is. I consider this extremely unlikely. This lens is a real joy to use. The tripod collar balances the rig nicely on a tripod, and allows vertical shots easily.
Manual focus is very nice, with a convenient focus throw and nicely dampened feel.
Rugged and constructed to the standards required by working professionals. A metal hood would be nice, though. The focusing and zoom rings do feel a bit on the plasticky side. Tripod collar could have been made detachable, but personally I don't find it an annoyance. Those who do can swivel the collar such that the foot rests at the top and slightly to the right so as not to obstruct the focal length setting.
