TOLD YA!!!! Both of my SPs have serial #s in the 3 range, I think, but I'll have to check. I've always wondered what the SN range for the SPn is, i.e. did they start a new series, just continue the SP range, etc. And what about the range for the UCs? Rich????
Stephanie: There are plenty of fast Olys. The SPs, some of the older 35 series (e.g. 35 LC), the RD, at least a couple of the the ECs, etc., had 1.7 lenses. No 1.4 like the Yashica though. But, that's not enough of a difference IMO. But I'd take Yashicas if someone gave 'em to me!
