I'm getting flare occasionally with this lens, so I suggest buying the square lens hood, as the standard attached hood doesn't cut it sometimes. I'll be ordering mine this week. Change that - I'll be ordering when Gandy gets back. I don't shoot b/w, (yet), so I can't say anything to that, but the lens is fantastic with color. As good as Zeiss? No, but you REALLY need to be pushing the lenses to spot the performance differences. Shoot with chrome and the Skopar can be amazing. I'll probably end up getting the Zeiss 28/2, but only for dof. That said, I WON'T be getting rid of the Skopar. The subtle vignetting and softening at the edges can be a wonderful creative advantage in the right circumstances.
