Vignetting

The most severe "problem" seems to lie between f / 2.8 and f / 4, but is pretty much gone by f / 4. There's a huge difference, though, in both the vignetting and metering from f / 2.8 to f / 4.  As this is the same pattern that my EF-S Sigma 18-50 / 2.8 shows, it leads me to wonder if this situation is endemic to f / 2.8 EF-S lenses.  Fortunately, this will not likely ever be a problem for me in that vignetting is more an issue when going for a deeper DOF -- it's often overlooked, or just not important, in shallower DOF shots.
