One of the smallest lens what I ever try, really, really small. I got positive impression. Sharp wide open and perform pretty well at every distance.
Any experience ? _________________ -------------------------------

And it has Elmar bokeh.
I see the same from the Argus Cintar (Elmar clone).
I am surprised this is a rare lens. This should have been cheap to make and very popular.
Attention Samyang! You can sell one of these to everybody who has a Bessa, Fed, Zorki, or Kiev ! _________________ I like Pentax DSLR's, Exaktas, M42 bodies of all kinds, strange and cheap Japanese lenses, and am dabbling in medium format/Speed Graphic work. |

Wasn't the 40mm Tessar for SLR ?
Or is there one for Contax ?
Also, maybe the Elmar is easy to tweak for wider angle. _________________ I like Pentax DSLR's, Exaktas, M42 bodies of all kinds, strange and cheap Japanese lenses, and am dabbling in medium format/Speed Graphic work. |

Yes, the 4.5/40 Tessar was for the Contax SLR. There was an 8/28 Tessar for the Contax RF.
It shouldn't be difficult to make a wide angle Tessar, you just change the front glass, after all this is what Zeiss did with the Pro-Tessars for the Contaflex. _________________ I don't care who designed it, who made it or what country it comes from - I just enjoy using it! |

The Contaflex Pro-Tessars aren't actually Tessars at all I understand.
They are pretty complex multi-element arrangements.
Heck, even the Pantar accessory lenses are 6-7 elements, not triplets. _________________ I like Pentax DSLR's, Exaktas, M42 bodies of all kinds, strange and cheap Japanese lenses, and am dabbling in medium format/Speed Graphic work. |

Yes, they are more complex, but what I mean is, it's just the frong glass of the Tessar that needs to be redesigned to make it a wider angle. You can make a 35mm Tessar, after all, the Minox had one, so I'm just wondering why Zeiss didn't make one and Leitz did (the Elmar being similar to the Tessar) _________________ I don't care who designed it, who made it or what country it comes from - I just enjoy using it! |

I thought the classic Elmar 50/3.5 is a cooke triplet (like Cassar-Anastigmat, Domiplan etc.) but I can't find any diagrams on the net.
I think they didn't produce a wide angle Tessar simply because the Biogon was better.

Leitz Elmar
It is sometimes thought that The Leitz Elmar 50/3.5 was a Tessar copy or clone. This is not the case. Although the lenses appear similar in layout, there is a lot more to the design and performance of a lens than simply the layout of the glass elements. The position of the stop, the optical characteristics of the glasses used for each element, the curvature of each lens surface, and the negative format which the lens is designed to cover, are all vital to the performance of the lens, and in the Leica lens these were all different to the Tessar. When the Leica was being developed Oscar Barnack tried a 50mm Tessar, but because it had been designed to cover only the 18x24mm field of a cine frame he found the coverage of the Leica 24x36mm format to be inadequate. The lens designed by Max Berek for the Leica rangefinder camera was a modified Cooke Triplet with five elements in three groups, the third group being three cemented elements, with the aperture stop in the first air space. This lens, called the Elmax, gave good coverage of the 24x36mm format and was used until improved optical glass allowed the third group to be simplified to a cemented pair and then lens was renamed the Elmar. It was not until Zeiss Ikon were developing the Contax camera to compete with the Leica that the Tessar was redesigned to cover a 24x36mm negative.[4] |

Thanks! Sounds very plausible I didn't know the a cooke triplet could consist of more than 3 elements (Tessar is also a cooke triplet). _________________ I'm not a collector, I'm a tester
