I have just received my fourth copy of this lens.

All of them seemed in pretty good external shape.

One had faulty internal mechanics,
One had a tilted focus plane,
One could not focus at infinity from 70 to 100 mm but was OK a part from that and I kept it. But corners were not perfect at 200mm.

I saw and ad for a 17 € copy and decided there was little to loose. Was described as perfect, like new. Like new indeed but with a fungy dot inside.

I tested it and was amazed. Perfect at all focal distances. So this one will stay with me and it is under an Ikea Jansjo UV lamp for an UV bath for a while.

Just for you to know that my excellent Minolta MD 75-150 has been trounced...

These late Tamron adaptalls are sub par regarding mechanics and quality control but the optical computation is very good. So it is difficult to find a good copy and you need to pamper it once you find one.


Did you ever tested the kiron macro 70-210 f4 zoomlock? I've read very positive thoughts about it, but never tried it personally

Fuji EBC Fujinon-T 3.5/135mm:





Konica AR 4/21mm "new" (on the right):



For quite some time I had lusted for the "new" AR 4/21mm with rubber focusing grip. Today I saw one at a local photo store, and so I got it ... It's the first time ever I've seen this version of the AR 4/21mm here in Switzerland (the earlier version with metal focusing grip occasionally appears on the local market). Nice find, and in an excellent like-new condition. Lens hood and the original lens case were included as well.

The newer version is performing quite a bit better when stopped down; wide open both versions are comparable (tested side by side on 43 MP FF). Not sure whether this is sample variation or (probably) a optimized computation. We know fro the AR 2.8/35mm that the the newer version with rubber focusing is much better than the older one - even though they have the "same" lens section.

I'm curious how this optimized version compares to other vintage ultrawides from the usual suspects, e.g., Canon, Mamiya, Zeiss Jena, etc., which, as a general rule, aren't very good out to the edges. I have a variety of 21st-Century rangefinder ultrawides, but my only one of the vintage SLR type is the Topcon 20mm/4. Actually, I have a '90s Tokina 17mm/3.5 in Nikon AF-D mount, but there's something wrong with it leading to blur everywhere outside the center at all apertures and distances, so it's basically just a paperweight.

My RMC Tokina 17 3,5 is quite sharp stopped down at infinity on 80% of the field. Edges and corner at the infinity setting are sharp at around 2 meters. Significant field curvature here. I do not know if a Kolari kind sensor would help.

Yeah, would be interesting indeed. I have quite a few 20mm/21mm lenses from various manufacturers (Canon, Konica, Mamiya, Minolta, Nikon, Olympus, Pentax, Topcon, Yashica, Vivitar and Zeiss) ... let's see.

A Vivitar Series I 28-90mm 2.8/3.5 zoom to replace my copy that had been knocked over by somebody. The concrete floor was not kind. The replacement looks brand new in original box, including all packaging and manual.

A Topcor RE 35mm 2.8 is in transit and I am eagerly awaiting its arrival.


Both great lenses. How is the aperture action on the Viv? This model is exceptionally prone to oily blades.

I got this Upsilon 200mm F/2.8 today for a $40 bid. Upsilon was a house brand for Sigma, this is the same as their XQ lens of the same description.

That's a lens I always was looking for - but it's quiute rare here in Switzerland. I have been using a smaple which belongs to a friend bakc in 2015, though. That particular lens was abit puzzling since it hat pretty visible astigmatism in the image center (!!) which would indicate serious manufacturing problems. I am aware of two other Minolta 5.6/400mm APO lenses, and both semm to have the same same problem. Peculiar indeed!!

Stopped down to f11 the lens was excellent; certainly much less CAs than my Canon 2.8/400mm L, but maybe a bit less detail (I don't remember exactly, though).

I really wonder whether your lens has similar issues at f5.6?!

Topcor RE 3.5cm 1:2.8 with damaged rear lens - should arrive tomorow. Let's see whether we can save the beast ...

Here 2 sample images ( weather not really nice here right now with smog from northern forest fires and overcast) both at F 5.6 with no PP. Both on Sony A7r using ISO 1600 in A Mode and Novoflex MD-NEX adapter all mounted on tripod
First sample at minimum focusing distance
Second sample at about 200 ft (66m) distance

I can't see any softness or CA on both of these and neither on the shots i took of the same subjects stopped down up to F 32 ( F22 and F32 do show some softness either due to some camera shake or to diffraction)

#2


Really favorably surprised that my copy does not match all the comments i see on the web about this lens.

High ISO and strong compression may "mask" some minor problems of the lens, but nevertheless your lens seems to be OK (i e no strong astigmatism in the image center). Good to know!

It's still a mystery to me why the three other Minolta 5.6/400mm APO lenses I'm aware of do have the strange astigmatism problem ...

Thanks a lot for checking and posting the images - I really appreciate it!

I bought a Metrigor 35mm f2.8 M42 mount online. The lens looks a lot like a Takumar, and has a M --- A switch - though I don't recall ever seeing an M42 Takumar in 35mm f2.8. Are any members familiar with the Brand Metrigor?








A shot with the Metrigor of my house gas meter cropped 300% to show the gauges



I'd appreciate any help you can give identifying this lens.

Thank you,

Mike

I'm curious about that one. A friend of mine had one (in the Sigma flavour) and was not happy with it. Let us know how it performs please.

That lens is almost certainly Cimko made (Cima Kogaku, which are usually recognizable at the diamond shaped focusing mark) . I have an almost identical "Rubimat" labelled lens. It is sharp in the center wide open, which is why I keep it. ☺️

See here album showing both the lens and some results with it. When seeing same scene, first picture is wide open up to the minimum F32 aperture setting:

This lens is definitely not designed for hand held shots, but on a tripod, i am really impressed up to now.
