Well, I've never used the Tammy, but the Siggy is A-OK in my book. Never mind the not-so-interesting photographs, but I like the sharpness and bokeh of this guy.

(all 300mm wide open -- on another note I should really just stop using zooms altogether because I tend to always use them at either the wide end or the tele end, not so much anything in between

)

I keep hearing that the tamron is sharper, but I hate PF and CA. Using this on the K20D, stopped down a bit, how likely am I really to see a big difference in either? Say, stopped down a couple stops from wide open most of the time.
