I can't tell what is the min focus distance, right now the ring is frozen
Will have to see how to approach this issue though.
On the shots I've taken there are lots of flares shooting with the light in front
I suspect this might be a tomioka (were they 8 elements)

thank you very much mate, the issue is that focus cannot turn to infinity, so whole group removal wouldn´t be possible.
On the other side there is the focusing frozen issue, so i would have to investigate further on, hopefully someone here would be able to advice me. Anyway, my lens is the 55mm and these samples are from the 50mm , but i would say they are very close one to the other (might be the same lens) would the optic be the same in both of them?

Yours is marked 5cm, so it is 50mm. You can screw. I repaired aperture in mine, it was stuck wide open. Someone had incorrectly reassembled the lens. It is still very wobbly. Not the best build quality from Yashica. It is usually a lot better.

you are right , i dunno why i was thinking in 5,5cm; brass and alluminum wouldn´t call it bad build quality, how is your regarding flares? i can see there is sharpness, despite very affected front element, but flares very bad.

All other elements are in pretty good shape , no fungus, even though lens came to me very dirty

It can flare pretty good.

G.A.S. had me again, I couldn´t resist getting this 35mm f2 Zuiko MC. It is like new, not even a single scratch, helicoid and aperture work just perfect, and very reasonably priced. Knowing of its reputation, loved by some, disregarded by some more, I since long wanted to see for myself, and here it is, proudly sitting on my beloved OM-3.


You have a very nice looking copy there! Show some images here when you have them. You are also quite correct about user's interpretations of this focal length and aperture range~ at least on this forum.

-D.S.


Hi Doc and all,

Thanks, I´m really happy with it and all its foibles.


#1 At f2, it glows. But I don´t shoot landscapes wide open. It´s probably something interesting when shooting portrait, but I haven´t tried yet. The glow is gone at f2.8, anyway. That image is a 100% crop from the edge of #3


#2 At f5.6, the same 100% crop from #3


#3 The full frame at f16.


#4 Look at the colour rendition and contrast.


#5 Snapshot at f4 with a bit of bokeh. The lens has springing sharpness and is easy and quick to focus. Useful - kids never hold still long Smile


#6 Flaring up against the sun in some situations.


#7 Just another sunset.


#8 Nice detail on the moss and some more bokeh, probably at f2.8, or so.


I can´t put my finger on it why yet, but I came to like this lens very much over the last three weeks. It´s certainly a keeper.

Looks like you got a good one, based on the imagery above.
Some pretty nice photos. Like 1 small Like 1 small

I actually had one here for a while, and was not able to use it with no native mount. It came in a box of stuff that was accessories and lenses that were included with a Nikon body~ likely one of the F2's. I got good trade in value for it. It certainly was very well put together, and seemed to be very high quality manufacture.

I'm having a lot of fun with the focal length, and am itching to get some vintage automobile photo's with my latest 35.

-D.S.

Latest example of the Konica Hexanon 57mm f/1.4 AR (EE) I picked up. A bit glowy wide open but with great center sharpness. Emphasizes cyans and red-browns like most Hexanons.

I already had the Kiron version, but that stuck wide open and has optical problems (fungus, separation)

Not MF lenses - but hey ... lenses are lenses!

Minolta AF 2.8/135mm (I had bought one around 1992 for a trip to northern Finland, but sold it later. Will be interesing to compare it to classsical MF 2.8/135mm lenses since the MinAF has internal focusing)
Sony AL 3.5-5.6/18-55mm (pretty good APS-C "budget" lens, much better than the earlier Minolta AF 18-70mm)
Sony AL DT 4-5.6/55-200mm (never had this one - I'm curious about its performance on APS-C)

I just purchased this Vivitar 35mm f2.8 on ebay. I haven't been able to find the 35xxxx serial number in any lookup lens number lists. Any idea who manufactured this lens. M42, screw in metal lens cap

Thanks for your help !

This is the 1967 version that pre-dates the well-known numbering scheme. Later examples that look identical to this bear the "22" Kino serials, so it's assumed they made the original ones as well.

Thanks very much for the information - I didn't know there was a time when the Vivitar serial / manufacturer list(s) don't apply. It is interesting to know this lens is likely made by Kino. I've read on the Pentax forum that Kino and Komine are considered to be the two best Vivitar lens makers - though I'm not sure if there's been a true, subjective test of image quality between the different manufacturers.

Thanks again

Mike

My pleasure.

I find the "rankings" to be more a general rule of thumb than a hard and fast rule that the Kinos and Komines are better than the typically later Tokinas and Cosinas. I surmise that most people are drawing those conclusions from the ubiquitous 70-210 lenses, in which the order from best to worst goes Komine-Kino-Tokina-Cosina. There are some Tokina and Cosina vivitars which are really great, and a few Kinos and Komines that are pretty meh. Those are the big four. Then of course, there are the rarities made by Perkin Elmer, Asanuma, Makina etc. which are best considered on an individual basis.

The regularized serial numbers are reported to have begun in 1970, so earlier than that, everything is pretty random. I can't find the exact date Ponder and Best adopted the Vvivitar trademark, but it's reported to be the early 60's, so there were a few years where the regularized number scheme was not in effect. There are folks on the Kiron Klub mailing list that know WAY more about Vivitar's history than I do, so if you want to dive deeper, I'd suggest giving them a visit over there.

I've got the Auto Vivitar 28 / 2/8 that has identical styling with a 56*** serial number - which according to thye list is Kyoe Schoji

Here's the Lens-DB entry showing a black and white photo of an example with a 22 serial number with identical machining and same focal length, but in all-black:
https://lens-db.com/vivitar-35mm-f28-auto-s-n-22xxxxxx-1969/

And here's an old thread showing a example that has the silver anodized band and a black nose but is otherwise identical:
http://forum.mflenses.com/vivitar-chrome-nose-lenses-are-made-by-kiron-photo-evidence-t30239,highlight,%2Bvivitar.html

Vivitar was more deeply involved in the overall design of the lenses they badged than a lot of the other rebranders, so you'll see lenses from different manufacturers with similar styling.

Unless I see one with the same styling and a Kyoei serial, I still think it's likely that the 35mm was always a Kino.

Interesting lenses indeed! Theses early Takumars never show up here in Switzerland, but I have the corresponding early Minolta W.Rokkor-QE 4/35mm which was a [5/4] construction - maybe a Tessar type master lens with an single-len wide angle converter in front, or (more probably) a triplet type master lens with a color corected doublet wide angle converter in front.

I don't own the corresponding early Minolta 4/100mm lens (a triplet as well), but its 135mm cousin 4/135mm (also a triplet) is surprisingly well corrected. Of course there is fiueld curvature (as with any triplet), but stopped down it is very sharp, and color correction is much better than with the later Minolta 2.8/135mm lenses.

I think the 100mm is rare no matter where you live. I've never come across one here in the U.S. I've seen a handful of the 35s, though. They always seem to be well-used, like D1N0's, though.

That early Minolta 4/100mm triplet (a preset lens) is a great lens despite being only f/4; I prefer it to the 4/135mm myself. I would suggest patience and you keep an eye out for one but I'm sure you already do. They do turn up on e.g. eBay every now and then (mostly in Japan). For a lens that is relatively rare there are a surprising number of minor cosmetic variants of it.
