Neat. Never seen one of those before.

I was pleased to spot this and lucky to get it for relatively little. There seems to be just the one thread here mentioning this lens. Very little comes up googling - no pics. It's very different to the long tokina made ones - tokyo koki, tokina vivitar etc and has a rather better spec, focussing to 10m. Shorter, doesn't separate into halves. I have just had a peek through the lens using my adaptall 02F eyepiece adapter by holding the 02F against the end of the lens, this gives 30x mag with a 600mm. I was surprised to note that infinity focus position was only a few mm out - the registration distances almost match exactly**. I must diy something so I can use the 02F on t-mount lenses. However an immediate complication is this lens has the faux 47mm t-mount. Anyway a positive first impression, sharp clear image by eye, little fringing.
** update registration distance for adaptall is 50.7mm vs 55mm for t-mount. The bayonet on the 02F engages in the adaptall mount on the lens to a depth of approx 4-5mm, so thats the almost exact match.

Alun -

I checked Ebay and indeed found a 35mm f3.5 lens by Kawonon that looks nearly identical to this Vivitar lenses. I also found a Spiratone 35mm F3.5 that also looked nearly identical. This leads me to wonder more about the 13xxxxx serial for Vivitar indicating that the lens was manufactured by Schneider Kreuznach? The following lookup list of Vivitar serial number prefixes indicates 13 = Schneider Kreuznach. Is it possible this lens predates the use of these prefix numbers?

http://camera-wiki.org/wiki/Vivitar_serial_numbers#:~:text=Serial%20Number%20System,-The%20most%20common&text=Under%20this%20scheme%20the%20first,the%20week%20number%20of%20manufacture.

Serial Number Prefix Codes
09 (or 9) Cosina Company, Ltd.
13 Schneider Kreuznach
22 Kino Precision
25 Ozone Optical Co., Ltd.
28 Komine Co., Ltd.
32 Makina Optical Co., Ltd
33 Asanuma & Co., Ltd
37 Tokina Optical Company, Ltd
42 Bauer
47 Chinon Industries, Inc.
51 Tokyo Trading (possibly a corruption of Tokyo Koki, a Tokina predecessor)[4]
56 Kyoei Shoji Company, Ltd.
61 Samyang Optics Co., Ltd
75 Hoya Corporation
77 Kobori Mfg Co. Ltd
81 Polar

Any further comments will be appreciated.



I agree with the opinion that traces this lens origin to Kyoei.
I have the same in Soligor version, but I didn't know that later on it would resurface as Kawanon.

BTW, the attribution of two serials to Schneider and Braun is questionable (at best).
Never seen anything marked Vivitar that could be traced to Schneider or Braun (which used Staeble, Steinheil, Enna, Schneider and I believe also Rodenstock optics, but I'm not sure ever made their own lenses).
Chinon attribution is also... a hornet's nest that I'm not willing to disturb Rolling Eyes

I have no specific knowledge of Vivitar serials. What I know very well is that in Soligor world the starting numbers don't tell the whole story. I found that at different times different makers used serials with the same first number/s. Often the length of the serial was different, thus allowing to infer a rule (see my own contributions to the Soligor serials thread).

Regarding Kawanon lenses, I know very little about them too. I just know that early lenses were branded with a different name: Kawakami. I own an old preset 135mm that's branded that way...

Nice find. Different from the usual ones.
You're right. It looks quite different from the Tokina made long achromats. I have one of them, an 800mm, that breaks in 3 pieces!

I'm curious. Is it an achromat or a triplet? What's the serial?
I might be wrong, the preset rings looks similar to those of Komine-made teles...

I see that you have the Tamron Adaptall-2 200-500mm 31A in your signature.
If you can withstand its weight (and bulk), it beats all the mentioned long focals by some margin.
Great Tamron design! And great usability on Pentax DSLRs wih the P/KA adapter. Setting the aperture with the thumb is invaluable!

This early Petri lens is famous for it's 7 element optical layout with a triple cemented element. This is the earliest version (I think) with A.C marking (Amber Coating?) instead of CC on other models, and a serial number in the 5XXXX range instead of the 7XXXX range used later. A thread already exists for the lens: http://forum.mflenses.com/kuribayashi-a-c-petri-orikkor-12-f50mm-t81360,highlight,%2Bpetri+%2Bac.html



The camera is also an early model of the M42 Penta featuring a different mechanical layout underneath the bottom plate than was used later on. The camera initially would not fire, but after being worked several times it fired into life, and the rubberised curtains are still in good nick. It still hangs up at lower shutter speeds.

Yes it is a special lens for sure.
There is at least one example of the C.C. with the 5XXXX serial, so I'm not sure that the A.C. - 5XXXX, and the C.C. - 7XXXX correlate (If that is what you were implying)
Beautiful bokeh and rendering from this lens, and it is usually quite sought after (and expensive)
Congratulations
Tom

The latter is a pretty rare lens as well (of course not as rare as the E 4/300mm) - while it looks like a re-badged Tokina 4/80-200 at first, it certainly has a completely different optical construction, and probably is a real Mamiya computation (remember - they had
excellent 4.5/105-210mm tele lenses for their 645 system back then).


After reading this comment of yours, I have bought Mamiya-Sekor E 80-200mm f4. Currently it is on the way. How do you rate its performance? Similar to the mentioned Tokina or better? I have one of those Tokinas - it's a solid performer. Not stellar, but considering its low price and wide availability it is also a keeper.


I just have been comparing the Mamiya Sekor E 3.8/80-200mm, the later Sekro E 4/80-200mm and the conteporary Minolta MD-III 4.5/75-200mm lenses. Images will later oin a separate therad, but here a few preliminary observations (24 MP FF, infinity, tested wide open and at f8.0):

@ 80mm: Mamiya Sekor E 3.8/80-200mm clearly is best. No lateral CAs at all, very good detail resolution even wide open in the extreme corners. The Sekor E 4/80-200mm has a nearly as good resolution, but slight CAs, and the Minolta has slightly inferior resolution at f4.5 plus slight CAs.

@ 135mm: Mamiya Sekor E 3.8/80-200mm again has the best resolution, very good at f3.8 and excellent at f8, but now also slight CAs. Sekor E 4/80-200mm as well as the Minolta 4.5/75-200 have a somehow lower corner resolution wide open, but stopped down they are as good as the Sekor E 3.8/80-200mm at f3.8.

@ 200mm: Again the Mamiya E 3.8/80-200mm has the best corner resolution wide open, but stopped down the Sekor E 4/200mm is comparable or even slightly better. Wide open the Sekor E 4/80-200mm has clearly a reduced corner resolution and quite strong CAs. Wide open, the Minolta is somewhere in between the two Sekors, at f8 it's slightly inferior to them both.

Over all the Sekor E 3.8/80-200mm wins - a result consistent with the elaborate tele zoom test by Walter E Schön, published in the early 1980s. As far I as remember the Sekor 3.8/80-200 was the best lens in the "resolution" departement back then (out of about 15 lenses tested). But of course this was before the arrival of lenses such as the Zeiss CY Vario Sonnar 4/80-200 or the Leitz R 4/80-200 (both were developped by the same lens designer - Lothar Kölsch).

Thanks for the detailed review. My E 4/80-200mm has arrived. Unfortunately there are slight traces of fungus or traces of condensate inside. Fortunately it is unlikely to affect the image much and the seller has issued a partial refund. All in all it costed me about $50. I haven't tried it yet as the weather is not that good but from outside it looks almost like new with the leather case and the original box. I think the lens was kept in the case for long time which probably caused the fungus or condensate occurrence.

That's a bit annoying of course ...! Anyway, I have several samples of the earlier Sekor E 3.8/80-200mm here, and if you are interested, you can have one for free, if you are willing to pay the postage. Just PM me.

Actually you're right, for some reason I thought the difference was significant. I looked through my stuff today and also have a copy with a 6xxxx serial. I'm looking for lenses to go on holiday in New Zealands South Island, and chose the Petri. It is no worse than similar lenses wide open, and quite good stopped down, and the 10 straight blades look good in night shots. We'll see how good it is in general in the next two weeks.
