Continuing the gear reduction:
All glass is clean and clear with no fungus/scratches/major dust issues, all apertures are clean, dry and snap quickly to set apertures. I've used them all and been very happy with the performance, which is to be expected. Focus and aperture rings function normally and to the high Takumar standards. Bodies may show some sign of use (minor paint/anodizing loss on aperture rings mainly) but realistically, they are all in good to very good shape. Will ship with caps and cheap UV/protective filters until I run out of them. Filter rings are un-dented.
The 50mms are all the 7-element slightly radioactive design.

I've done somewhere between 15 and 20 deals here on APUG and I'm on ebay under the same user name with ~50 feedback, all positive. Ships from San Diego, CA, USA and I will ship worldwide but PM for more info on that.
