It could be said that rear is very similar to Tomioka 100mm clones (check last photo on that page where 4x screw is nicely visible): http://forum.mflenses.com/viewtopic.php?t=41307&start=15

Question still remains: is Tomioka responsible just for the optics inside the lens and if so for which lenses of the series? Or did Tomioka produce whole series including lens body.


The lenses in the thread you've linked are not Tomioka but Sun. Here is the Tomioka 100mm f2.8 lens http://forum.mflenses.com/tomioka-100mm-f2-8-t49746.html

The lens in this thread indeed shares some details with other Sun made lenses but on the other hand has some obvious differences with other Sun lens I saw before. For example I never saw Sun lens with exposed retaining ring like this lens has on its front.


Interesting. So is the Prinzflex here: http://www.yaotomi.co.jp/blog/used/2009/09/prinzflex-auto-reflex-100mm-f28-m42.html
SUN or Tomioka?

Then SUN would also be logical solution to Beroflex / Berolina / Elicar / Alpex / Universar silver line:

This looks also exact like mine but silver... The only thing is that this one does not have extending hood and one I have has one. Same letters, screws position, etc.

Did SUN make it or someone else?

Wow, the "Universar 300/4.5" 's little brother.

The pipe is metal and the rings plastic, I suppose.

Dimitry would you please share some info on your SUN references. It's quite a discovery. There are a lot of lenses that could now be distinguished as SUN. And if i may say these are mostly good to very good lenses.

Need to modify myself here...

The number 6 on the aperture rings is different, therefore not sure if it is Sun Optical Lens while all Sun made lenses have the same numbers. The good thing is that adapters should be soon here and I can test it.

Here is the list with Sun made lenses: http://www.ephotozine.com/equipment/manuals/Sun-Opt/201

There is no indication about 135mm 3.5 lens there... I am a bit skeptic that Sun made it.
Also the missing collapsible hood is missing on Sun lenses. Confused

Just received adapter and here are some samples, taken with Olympus Pen E-PL1, hand-shoot, wide open at 3.5, no PP / straight from camera just resizing:







100% crop







100% crop





Opinions please... Crop of the pictures randomly taken. If everyone wish I can crop others too. Just let me know.

Nice samples. I had this lens open & apart. It's Sonnar (Zeiss) copy with thick large chunk of glass inside
that can rarely be found in third party lenses. Here few full frame samples (sorry to steal your topic a bit):

Hey no problem at all... Feel free to post whatever you want but which one did you took apart? Silver one above? So far I really like this lens especially that I paid 11.30$ and got also 3 months warranty. Got it at retail store... and it is like new condition or maybe it is new, who knows!

and if it is Tomioka, he had produced lenses for Carl Zeiss too and it is good possibility that you have something there or we have... Laughing

I don't have references, only observations and logical conclusions. Here we go:

1. In the Soligor thread http://forum.mflenses.com/soligor-12-8-f28mm-21and-versions-t30866.html lenses with serial numbers starting with 27 and 7 were recognized as Sun made. I can confirm this since I have 28mm F2.8 Sun lens and they share a lot of details.

2. I have/had these 2 135mm F2.8 Soligor lenses with s/n 782864 and 2763333:






In all these pictures the lens with s/n 782864 is on the left. As you can see these lenses indeed share many common properties and most chances both are made by Sun. I saw in that Soligor thread that you have 2 28mm Soligor with s/n starting from 27 and 7 and they are also similar to these lenses above so you can confirm their similarity.

3. I have this 100mm F2.8 Soligor lens:





Here you can see its comparison to the above 135mm lens s/n 782864:





And all 3 lenses' reflections. In the real life the reflections are even more similar, almost identical:


I think it is safe to say that all these 3 lenses share many common properties so the 100mm also is made by Sun.

4. Now compare this Soligor 100mm lens to the Chinonflex and Pentor lenses in this thread http://forum.mflenses.com/chinonflex-100mm-f-2-8-in-m42-mount-t18348.html and Porst, Berolina etc. lenses in this thread http://forum.mflenses.com/tomioka-t41307,start,15.html

5. Compare it also to this Hanimar http://forum.mflenses.com/viewtopic.php?t=16881 and this Vivitar


6. Compare it also to this Vivitar lens






7. As to other focal length lenses - many 28mm F2.8 lenses are made by Sun since they are similar to the Soligor lenses. Compare your lenses to this Soligor taken from that Soligor thread


I think now you will be able to recognize that many 28mm F2.8 lenses found under different names are made by the same maker.

8. In the same Soligor thread lenses with s/n starting with 4 are also recognized as made by Sun. Compare again your lenses to this newer MC Soligors



The last one has a rubber grip. Now compare your lenses and these MC Soligors to this Porst 35mm F2.8 http://forum.mflenses.com/porst-weitwinkel-35mm-f-2-8-auto-t50153.html

I think now you agree that it is also made by Sun. And if the comparison to 28mm is not enough here is Porst 135mm F2.8 from almost the same line as the above 35mm. Compare it to the above 135mm Soligors:



The only things that spoils the picture is that some lenses seem to have the same A/M switch as Sun made lenses. For instance Korean lenses in your thread http://forum.mflenses.com/porst-weitwinkel-35mm-f-2-8-auto-t50153.html. Or the lens below - I don't think it is made by Sun but may be I am wrong:





I can only guess that either Sun has sold their facilities to a Korean maker or both has sourced their parts from the same maker.

and what do you think the lens I have "Dimension" is it made by Sun?

Yes I think it is made by Sun. Try to compare the reflections of your lens and the pictures I have posted above.

here are some pictures where you can see the reflections however they do not look similar to me, but I am no expert and do not know where to look or for what. Strange that none of those lenses have a built-in collapsible hood that this one does and it does have auto/man switch.

Sorry I didn't show this on the pictures but both 135mm and 100mm lenses do have build-in hood. I've added a picture now.

Hard to tell about reflections from your pictures. Try to see yourself in daylight. Try to compare also the rear lens. It could be though that since this is F3.5 and not F2.8 the optical formula is different and the coating as well.

to be honest, the test photos look better than the lens itself. Hope you didnt pay much for it
because it wont have much resale value. Rolling Eyes

I didn't pay too much... Whole 11.30$! Probably while no one knew what it is...

Just to add something that might ID the manufacturer is that the back element of this lens is perfectly flat what wonders me while mostly other lenses have a concave element at the back. I still tend too think that Cosina is manufacturer and not the Sun. Also under the collapsible hood when fully extended (manually slides out) I have two screws, facing each other at 180 degrees and I do not see it anywhere on the other lenses similar looking.

Here are some more reflections for Dimitry...

There is only one screw under the hood on my lenses but I don't think this is very significant. Rear element and reflection are different due to a different optical scheme - after all this is F3.5 lens and mine is F2.8. I still think they share many common properties.

Some more test pictures... I am just wondering if it is Olympus magic trick or the lens itself... I like the performance so far.

If anyone wants some 1:1 crop please let me know...

It's definitely a razor sharp 135 f3.5 lens!

This is an absolutely great lens

I am interested to see all crops but it's more than clear that the lens is a hidden gem

Or am I wrong?
