Cooke Triplet lens - any for M's

[eric rose]

I love the look these lenses give. Where any made for either LTM or M camera's? Not interested in Tessars, well actually I love them too but I am looking specifically for Cooke Triplet's.

The Perar 35mm is a Cooke Triplet I believe.

MS Optical makes two triplets, 28 and 35mm. They are tiny and fun to use.

I have an ms optical 28/4. Because there's not much in the way of speed and shallowness, you don't really get that Cooke Triplet look.

I was actually wondering the same thing yesterday when I when I was playing with my c-mount 1 inch f1.9 on my xpro1

I would think there must be a few in LTM which could be adapted, but I can't think of any right off the top of my head. Except for the Schacht Travegar 3.3/100, but good lucking finding one (also since they made the same lens for enlargers some people are fooled into thinking M39 versions might also fit LTM cameras).

I'm sure the Japanese must have had a few triplets too.

It will be perhaps easier to find an and old SLR. I think those two lenses are close to a Cooke Triplet
- Meyer Trioplan (commonly found in Exakta and M42 mount in a 100mm 2.8 variant)
- Zeiss Jena Triotar (135mm 3.5 or 4, M42, Exakta, perhaps Contax RF)

There are lots of triplets for SLRs: Meritar, Domiplan, Iscotar, Isconar, Westar, Iscovitar, Cassaron, Cassarit, Cassar, Victar, and some Japanese oddities. By the time the Japanese got into the SLR market most opted for Tessar designs for their cheapest lenses.

There are also lots of non-Leica-compatible RFs that have or take triplets.

Leica also made a three-element version of the 90/4 Elmar. It isn't a straight Cooke triplet as you can see from the diagram on the box - (a random ebay listing that google image search brought up). Note the thickness and the slightly concave inner surface of the front element. Nevertheless, an interesting lens, reportedly very good quality but with a distinct fingerprint.

Sadly, it's a rare lens selling at collectors' prices - 600-1000€ depending on condition and extras, I think.

Thanks for all your help! The quest continues.
