Today I've tested my one and only Soligor lens in LTM on my Ricoh GXR-M.
Actually I don't know much about this lens except that it carries a H33xxx serial number and is made in Japan for the German Soligor company. The aperture consists of 10 blades.
I didn't find any other lens in similar focus length and max. aperture in LTM so I don't know who did produce this lens.

However, at least it produces some nice pictures. Wink

The quality isn't bad at all. I was rather surprised.

The boaring test pictures:

1. Infinity landscape stopped down to F11:



2. Apprx. 15m distance fully open F4:



3. MFD apprx. 1.5m at F4:



4. Same as before but with 25mm distance ring at F11:



5. 100% crop of no. 4:



Lens shade was used (as usual) and RAWs have been converted and downsized in LR with minor adjustments but without sharpening.

Comments are welcome.

Cheers,

Pictures of the lens (just quick and dirty):

Probably the same lens as the common 4/105 T mount made by Tokina.

Thomas - you say it's LTM fitting - is that actually with rangefinder coupling?

It has rangefinder coupling yes. I have it too and think it is Tokina made. Quite nice as you say Wink

Stephen, as Nordentro mentioned, it's a real LTM coupled lens.

And yes, it maybe a Tokina lens, though there is no comparable Tokina lens in existence which is somehow strange.

Bottom line is that it's more than usable and delivers quite nice quality. I didn't realize shortcomings like CA's or alike, not even fully open at F4.
It's a solid metal construction and also the filter thread diameter of 40.5 mm is quite common for such lenses.

It can be found quite cheap and is available from time to time on "evilbay" or alike, though it's rather rare.
Besides the 105mm lens there was also a 35/3.5 and a 135/3.5 from Soligor in M39/LTM available according Camerapedia but I haven't seen them up to now.

It's the same as mine, I also suspect it's a Tokina. Whoever made it, it's a nice little lens .

There is one small drawback, it vignettes hard far out in the corners on FF (mechanical vignetting).
I have seen this lens as Seastal Ojasi branding too:

And if you google that brand, this lens shows up which is a Tokina also branded as Soligor:

You're right, that's exactly the same lens. It even has a H33xxx serial number.

Sad to learn about the incompatibility issue with your A7. Luckily that's no issue for me with my Ricoh.
One more reason to stay with the Ricoh for RF lenses. Wink
