Very sharp with high IQ, the only drawback is its annoying zoom creep.

The IS only has one mode on or off, there is no Mode 1 or Mode 2No zoom lock, not that zoom creep is an issue at this point in time when looking up or straight down, only time will tell if this is an issue

My only two complaints is that the canon box is not sealed; so, anyone could handle it before it arrives and it has horrible lens creep
