Upsilon was Sigma/Sun's own "off" brand. The same lens was also sold under Spiratone's name. I have one of those plus an Upsilon 200/2.8. They are mostly interchangeable YS mount lenses. Performance was not bad but not in the same ballpark as an SMC-T 300/4 (have one of those also). Kent Gittings

I don't remember the brand right now, but I think it might be Upsilon. With a k-mount adapter it works pretty nicely on any Pentax camera. I'm looking to get $75 for it + shipping costs. (estimated around $10 in the US via USPS ground). If interested, contact me offlist. Illinois Bill Kane - This message is from the Pentax-Discuss Mail List.
