Thanks for sharing!

The only lens in the RE Topcor line with MC is the RE GN Topcor M 50mm f/1.4. The Topcor 28/2 and 35/1.8 are prototypes which never went into production. Wink

I was guessing Pentax would have the lead in multi-coating before I clicked on the message link. Yep, they had a huge lead over everyone else back in '73. Interesting to see that Fuji was already using their famed EBC coatings in 1973 -- I guess I'd thought that it came later.

I just took a look at the FD lenses at Canon's Museum. Turns out they released their SSC line in March, 1973. So, this article, dated May, 1973, must have been written before Canon's new multi-coated lenses hit the market. Given the lead time some magazines have between writing and publication, this seems about right. Unfortunate timing on Popular Photography's part. At least the author of the article included the necessary disclaimer "As of this writing . . . "

Many thanks for letting us part in this interesting article!

But one fault is to mention: Zeiss 2/120 for Hasselblad was never made Wink

Later 2000F lens was 2/110 T*

No mention of FSU lenses? Cold War carryover? Nor does it distinguish the fact that many multi-coated lenses were, in fact, one coat with several ingredients. Good read though. Cool

It's interesting to see Spiratone on the list, Fred Spira was certainly determined to sell quality products at affordable prices.

When the RE GN Topcor 35mm 1:1.8 M lens was announced at Photokina in 1974, it was announced as multi-coated. That and the RE GN Topcor 50mm 1:1.4 M lens are the only SLR lenses Topcon marketed as multi-coated.

The 28mm 1:2.0 lens was an earlier prototype, before Topcon claimed any multi-coating.

I have all the other Topcors on that list, all their coatings reflect just blue and gold, nothing that looks multi-coated.
