Congratulations!
Nice lens and it seems to have an m42 mount. That will be easy to convert.
Mine came with a Praktina mount.

TTArtisan 11mm F2.8 Fisheye



Sharp from wide open, sharp across the frame from F4 on A7RII. I don't think I need to use more than F5.6 to get the best sharpness from near to far away.



As there are lots of test on the internet with FF camera. I will test it with aps-c camera and post the result later.

The Mamiya Sekor E 2.8/35mm (a rather uncommon lens here in Switzerland) finally has arrived, together with an Osawa 3.5-4.5/35-105mm with Mamiya E mount. I'm rather curious to evaluate the performance of the 2.8/35mm.

The Osawa 35-105mm on the other is NOT the same lens as the Mamiya Sekor E 3.5-4.3/35-105mm (reflections on their glass surfaces are clearly different), and the Mamiya Sekor E 3.5-4.3/35-105mm has NOT the same glass as the corresponding Tokina RMC 3.5-4.3/35-105mm. Interestingly enough, the Minolta MD-III 3.5-4.5/35-105mm (I) seems to have the same glass elements as the Tokina, though - even though the Tokina is listed as 3.5-4.3, while the Minolta is a 3.5-4.5 ...

Since my pristine looking S-M-C Takumar 2.5/135mm (II) obviously is de-centered, i just got a K mount Pentax 2.5/135mm which should have the same optical formula. Not yet arrived, but reasonably priced ...

Really wide with 11mm!

I look forward to see what the Sekor E 35mm can do if you make any tests. I have one too but no adapter still.

Yes. Much wider than those 16mm Fisheye!

Like 1

Very good use of the Fisheye effect.

Thank you - yes it was already modified to M42 from Altix mount.
Do you have some images taken with yours?
There are not many pictures taken by the Telefogar on the net, and I am keen to see some more before I try it for myself. Mine is still in transit.
Another lens I am awaiting is this one.
Not common - and not in widespread use:

I have just been comparing a dozen or so lenses at f=35mm (including the two Zeiss zooms ZA 2.8/16-35mm and ZA 2.8/24-70mm).
As usual using 24MP FF, and at infinity (landscape photography).

Carl Zeiss Jena Flektogon 2.8/35mm
Konica Hexanon AR 2.8/35mm ([6/5], metal grip version)
Konica Hexanon AR 2.8/35mm ([6/5], rubber grip version)
Mamiya Sekor EF 2.8/35mm
Minolta MC-I 2.8/35mm [7/6]
Minolta MD-III 2.8/35mm [5/5]
Schneider Edixa-Curtagon 2.8/35mm
Topcon Topcor RE 2.8/35mm
Yashica ML 2.8/35mm

Minolta MD-III 3.5/35-70mm Macro
Zeiss (Sony) ZA 2.8/16-35mm
Zeiss (Sony) ZA 2.8/24-70mm

Results will be published soon.

EDIT: Here's a teaser: Mamiya Sekor EF 2.8/35mm (top row) and Minolta MD-III 2.8/35mm [5/5] (lower row) at f2.8 (left), f5.6 (middle) and f11 (right). 100% crops from the corner of 24MP FF JPGs from the Sona A7II.



As usual: Click twice on the image to see its full resolution!

I wonder how sony would deal against old technology .
Revuenon ef (mamiya) 50mm 1.4 seems very sharp in the middle wo but more CA visible than zeiss planar.

Sony got smoked. I would also guess the Minolta will be no better than 3rd out of the lenses you list. I would think that at least two of the following the flek, Topcon, and curtagon will beat it.

Yes.
I have been looking for one for quite a while.
This one looks promising.
It supposedly has the same optical construction as the Pancolar 55/1.4 so I am very keen to see how it paints.

You may be surprised Wink

http://forum.mflenses.com/test-nione-vintage-2-8-35mm-lenses-on-24-mp-ff-t82723.html

It's pretty obvious the 1982 Minolta MD-III is much better than the 20-25 y older lenses you mentioned. No surprise to me, even though the Curtagon may well have been the best 2.8/35mm retrofocus of its time (1958).

Thank you for the link - I had not seen these images of yours.
I am particularly impressed with your portraits.
Well done

Another Vivitar series 1. The 28-90mm 1:2.8-3.5 macro focus by Komine. Note the distance markings on the lens body instead of the focus/zoom ring.

Beautiful lens!!
It seems to be a varifocal lens, not a zoom? Focusing seems to change when the focal length is changed?

Yes, it looses focus when zooming. Like the Vivitar Series 1 35-85mm F2.8 (made by Kino/Kiron) Where it is mentioned on the name ring. I don't mind because I always zoom before focussing. Varifocus to me sounds like a flaw made into a feature in order to simplify the lens design (you say better IQ due to variable focus). I'd still call it a zoom because you slide to change FOV and turn to focus. But you can also slide to focus within part of the focal range. There was also a Kino version that didn't make it to Series 1 https://www.pentaxforums.com/userreviews/vivitar-28-85mm-f2-8-3-8-variable-focusing.html Also sold under the Kiron brand.

Congrats! Praised by many but some claim not so sharp on modern sensors. Would be glad to hear your opinion. I passed many times on this one in my query for the ultimate transtandard because of weight.

Well, maybe you'd better avoid those beasts then ...:



Varifocal as well, patented around 1968, fast (f2.8 troughout the entire range), wide-to-tele (35-100mm ... most difficult to construct), and heavy.

It looks sharp enough to me on first impression. Soft when used wide open at the long end, but that doesn't surprise much and is probably intentional for portraiture. Some of the Tamron Adaptall SP-2 glass may be sharper. But this range and brightness can't be found in AD2. The 27A 28-80mm 1:3.5-4.2 comes closest and that too needs to be stopped down in the long end.

Can I ask you a question?

I love the rendering of the Meyer Oreston 50mm f1.8, and I've always heard the Meyer is a cheap version of the CZJ Pancolar 50mm f1.8. Is it true that both have similar bokeh rendering, but the CZJ is superior quality? I've never own both to compare, but looking at specs I see a difference; the Oreston has a minimal focusing distance of 30cm while the CZJ is 35mm.

Now that the Oreston goes for 150$+, which is the same price as the CZJ, if they have the same rendering, I might as well go for the CZJ. Do you or anyone can give some feedbacks?

(Also, is the Pancolar "auto" the same as "electric"?)
