Super-Komura 100mm f 2.5, Help with mount info please

Got this lens locally (Super-Komura 100mm f 2.5) together with an Olympus OM 130mm f 3.5 for 20 GBP, it feels very nice and solid , reminds me of Russian lenses like Tair 11a but a lot smaller, I didn't even check the mount until I reached home . It says on the back: Komura UNI AUTO for PETRI V2-6
Now I tried to do some homework googling without much luck (I found similar with m42), I would definitely want to try it myself, so .. any chance to adapt this strange mount.
Many thanks in advance


Badr

- First, you got a tremendous deal, these Komura 100/2.5's go for a lot more than you paid.
They are very collectible.

It has one of Komuras interchangable mounts, this one being the earlier Auto lens mount.
If you can find one, another Komura auto lens with a mount for another camera system (Nikon, M42, etc.) should interchange.
I have heard though that there are two variants of the Uni Auto mount, so beware.

Komura was an odd outfit that produced no less than four interchangeable mount SYSTEMS.

SLR adapter for Komura Visoflex-type tele lenses (M39)
Unidapter (M44) for preset lenses - like a T-mount, but Komura-only
Uni-Auto for Auto lenses - this came in two variants I believe
Komuranon interchangable mount for later lenses with open aperture metering functions.

An alternate fix for your problem is to find a Petri adapter. These are available for some modern digital.
I think I saw one for Sony E (Nex, etc.)

Very Glad to hear that thank you, I will definitely start hunting auto lenses

I use Sony a6000 and fuji x-a1 with adapters, previously nex 3 I can't remember when I last used af lenses with them probably less than 10 shots ☺
I have also Sony a58 to use the Minolta-AF.
I know, more gear than my best shots 😊

a bit late comer here, you can find also a cheap Komura (universal mount) lens such as this.



mount part, this is for Minolta SR mount (when set this to the green position, the lens has auto aperture mode)

That Komura 90-250 zoom is actually rather nice, for a late-60's zoom.
And quite stylish too I think.

Interesting!, currently not much offers on the bayE, not sure what to do.. I think I will get the adapter and/or wait a bit for a spare or repair one

Set yourself up an email alert with the a good search term, if you have a smart phone, you can receive and view them very quickly.

There are many Komura lenses available in Japanese auction site "Yahoo Auction", you can bit
into this auction from outside of Japan. There are now 4 SUPER-KOMURA 90-250/4.5, two are
US$8 and the other two are about US$12 for example. I did not check their shipping fees.
They are mostly SR-mount ones, some are Canon FD mount.

Note: I never used this Yahoo auction, so you should take care yourself.

Thanks, this will keep me busy for some time.

Wife wasn't impressed though, she didn't like the 'new front' ☺

Well, after not so long wait i found this:

http://www.ebay.co.uk/itm/311556875014?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

With M42 mount, the lens was described as faulty and I was hoping that the mount is intact. To my surprise it is fully working with clean glass,only some scratches to the body.
I Haven't got a chance yet to try the 100mm, but seems great from a few indoor shots.

The 90250mm feels nice reminds me of minolta colour ( if there is such a thing), it is more to the warm side. It flares but that is expected anyway
Here is a raw image with some PP @4.5(wo):

And here is a JPGS OCC with neutral setting at 4.5 , Auto WB, probably needs some contrast:

Komuras are noticeably "warm".
I think the color is more " Golden", a bit.
