I've recently come into possession of a nice Super-Multi-Coated Takumar 20mm f4.5. While googling around I found one source that indicated that the S-M-C version was an improved optical design (specifically mentioning an improvement over the earlier Super Takumar's distortion. (Now I'm having trouble locating that page again). The Ultimate Screwmount Guide seems to think that the Super Takumar and the S-M-C versions are the same and only differ in coatings. Another source ( http://www.aohc.it/tak02e.htm ) indicates a 5 gram weight difference between the two versions (which may or may not say anything about the optical design). Does anyone have any other sources of information that might shed light on whether they differ only in coatings or if it is more than that? Thanks in advance. -- "The key to seeing the world's soul, and in the process wakening one's own, is to get over the confusion by which we think that fact is real and imagination an illusion.
