Did a pretty thorough search of the archives to find not much posted about this lense. I've read the ~ 50 reviews of this floating around from users of other camera makers (not sure if there's some unofficial cultural taboo about using other brand names in here) and it seems very good to slightly mixed.
Google failed to release any resolution pixelpeeping on this lense either, so if anyone owns it and has some anecdotal evidence and/or comparisons they'd like to swing my way, then I'm all ears! I know it was just the other day that I started one on the F 50/2.8 macro but at least this way it's easy to map my growing collection! Thanks, Alex
