For some lenses, yes, for others, no. FYI, the "optical formulas" presented on Boz's site are interesting and give some insight into the lens's design, but they are not complete optical formulas. Lens element and group configurations can be identical, but designs may still be significantly different due to different glass formulas surface figures.

I've been looking around trying to find out and have seen a few references, but not for every lens. Boz's site has the "K" optical formulas, but I haven't seen a similar site showing the late SMC Takumars. Any help would be appreciated.
