A very special lens
Everyone should get one while they are still cheap.

I already had a copy of this, but a previous owner had disassembled it and removed part of the aperture linkage. This copy was a reasonable price, much cleaner, but required the aperture to be freed up. Works perfectly now, looks great. |

A weird mix of crazy lenses from the wastebin of the local photo store:
* a huge (huge!!) Auto Tamron 2.8/28mm
* a beautiful Schneider Retina-Curtagon 2.8/35mm
* an Auto Revuenon 2.8/35mm
* a similarly styled Auto Chinon 1.7/55mm
* a Pentacon Auto 1.8/50mm which nicely complements my Pentacon Auto 2.8/29 and 2.8/135 lenses
* an Auto Revuenon 1.4/55mm with completely flat rear lens
* an auto Beroflex 2.8/135mm
* an Admiral Automatik-Teleobjektiv 3.5/200mm
* a VEB Optisches Werk Weixdorf Konverter 2x
* and finally a Kaligar 3x Auto Tele Converter
I've only tested the Curtagon, which 1) extremely small and 2) extremely good at f11 (no CAs at all). And that one fits nicely to the Curtagon 4/28mm / Ysaron 2.8/50mm / Tele Xenar 4/135mm set I recently bought.

Well, I think that both lenses are six element designs, and may indeed be very similar in their layout.
The 45/1.8 has to make room for a shutter as well as the aperture mechanism so there is that obvious difference, apart from the focal length of course.
Apparently the 45/1.8 has a very good reputation for sharpness.

Here a few images of the lenses mentioned above.
First the "new" Schneider Retina Curtagon 2.8/35mm, here shown with a Retina III and three oter lenses acquired earlier this year (Curtagon 4/28mm, Ysaron 2.8/50mm and Tele Xenra 47135mm).
The Retina Curtagon is tiny, precisely machined, and operating smoothly. A real joy to look at and to play with!
The next two lenses - an Auto Revuenon 2.8/35mm and a Chinon 1.7/55mm - look as if they were made by the same manufacturer, even though there are some minor differences when looking carefully at the engravings. The 2.8/35mm is an average performer, similar to many first-generation retrofocus lenses of similar specs. Corners never get really sharp, otherwise quite OK. The Chinon 1.7/50mm has very little lateral CAs; otherwise it performs similarly to many normal lenses of the same period.
Then the huge Auto Tamron 2.8/28mm. Very well made, focus is still very smooth - its performance however is very low. The Minolta MD 2.8/28mm shown here as well is much better at f2.8 than the Tamron at f11! And the Minolta gets much better when stopping down to f8 ... which means the Tamron is not recommended for landscape and the like. Clearly the worst 28mm lens I've ever encountered.
Another "low performer" - the Auto Beroflex 2.8/135mm. Some say "there is no bad 135mm lens" - but hey: here it is! The lens is very small for a 2.8/135mm, but at f2.8 only the very center is reasonably sharp (and quite low contrast). There are lots of lateral CAs, and - as with the Auto Tamron 2.8/28mm above - even at f11 pretty large areas simply are blurred. Does anyone have an idea about the manufacturer?
Finally two better lenses - first the Admiral Automatik-Teleobjektiv 3.5/200mm, here shown side by side with the corresponding Hexanon AR 3.5/200mm:
The Hexanon certainly has a rather good reputation. but the Admiral is (slightly) better than the metal grip version of the Hexanon AR 3.5/200mm (not shown here), and about as good as the later (rubber grip) version of the Konica Hexanon AR 3.5/200mm shown here! Pretty surprising, I wouldn't have expected that.
Finally the Auto Revuenon 1:1.4 f=55mm. I can count five reflexes in front of the aperture and seven (one of them weak) behind the aperture - which corresponds to a classical [7/5] double gauss derivative. The rear lens is absolutely flat => Tomioka? Its aperture is very slow and closes only to f4, which means I have to clean it As with all contemporary f1.4 normal lenses, at f1.4 it has a low contrast and lots of coma. At f4, however, its surprisingly sharp and (unlike most other f1.4 lenses i know) there are no CAs!! Certainly a lens I'll have to look at more closely.
That's it for today! A very mixed bag indeed, but hey ... it was all for free

This is just a guess - but I believe Cimko (Cima Kogaku) lenses are known for having a diamond on their depth of field scales. |

Agree. I've seen this lens from quite a few rebadgers. It was the focus of a brief flurry of interest on a Manual Focus facebook group a year or two back. The proponents were quite enamoured of the lens for more or less the exact reason stevemark is not. |

Thanks for this information! Those cheap 3rd party lenses are not very common in Switzerland, and I simply took it with me out of curiosity.

Interesting - I wouldn't have considered the Auto Mamiya Sekor 3.5/200mm (II) as the same lens, but maybe you're right

[sellers pic] I just found the Argus (Mamiya Sekor) 135/2.8 companion to the Mamiya made Argus SLR (the one with the 58/1.7 bayonet lens). Been on the lookout for it for a little while now. Listed with frozen focus and stuck aperture, but you take what you can get. I'm interested in whether this lens is the same formula as the Prismat NP and Sekor-Nikkorex lenses. |

That one looks more like the Vivitar 28xxxxx. I was talking about the one pictured here: http://allphotolenses.com/lenses/item/c_2537.html#prettyPhoto _________________ pentaxian |

Some images made with the Petri 7 4,5cm 1.8. Actual focal length is 47mm. 8 blades aperture. On FF the corners are weak, CA is however quite good controlled.

I've got this Cimko badged as Super Paragon, the store brand of Photax, and it's a great lens. I've had it for years, it's one of 26 M42 135's I've got, it's not the best - but it's in the top few. _________________ LENSES & CAMERAS FOR SALE.....

Strange mismatch indeed! I have tested these lenses at infinity, as usual. When I look at your images (http://forum.mflenses.com/super-paragon-cimko-135mm-f2-8-t42752.html) they were taken at much closer distances. I'll check the Beroflex (Cimko) 2.8/135mm again near its MFD. At infinity, however, there are pretty funny (and pronounced) CAs, and the outer parts of the image don't get sharp even at f11 (using 24 MP FF) - certainly not what I'd consider as "one of my top five 135mm lenses"

My copy of the lens didn't have much fringing, but did have noticeably lower resolution at the edges, even at F8. The distance here is >100m, not sure exactly what it is. I didn't really get any shots in better weather to test the contrast. I have now sold the lens. |
