Sigma 600mm f/8.0 Mirror Lens Sample Photos and Specifications

Depends how you define sharp :D Mirror bokeh is fine with me :D I like 
donuts!

For me real sharpness starts around the 2.8/80 Biometar (the kit lens 
for Pentacon Six TL). Or you can use the Carl Zeiss Jena Sonnar f2.8/180 
for P6 or f3.5/135 Sonnar. I highly doubt any mirror lens will be able 
to give that kind of sharpness. And these are old lenses as well :D

I also saw pictures with the 5.6/500 Rubinar and that lens was quite 
sharp too. But I will be happy to see some pictures (RAW preferred) with 
your Tamron and K10D (or whatever camera you have). I am really curious!
