Got a copy of this lens by chance. Pretty small, on the size of a 50mm f/1.8. C/Y mount. I was always wondering why Soligor made C/Y mount lenses, as Contax users I guess wouldn't even consider Soligor. Anyway, here are two sample pictures for flowers (which may not be a good use of this lens). When I get a chance going outside, I'll further see how it behaves.

Is this a 28mm or 20mm?

Price, certainly. But this compact Soligor (if C/D version) is a solid performer and was a viable option. I suspect a Kobori/Koboron lens.

Oh very cool! It sort of has that soap-bubble bokeh going on there in your first image. I have been on the lookout for one of these Soligors. From my previous searches, it sounded like this same lens may have also been branded as a Spiratone Plura-coat 20/2.8 or as a Cambron 20/2.8. But I haven't seen this proven out necessarily. They all do bear striking resemblance though.

It is the 20mm C/D MC version.

The front ring does have the C/D and MC. The multi-coat seems quite effective. To me, it looks Kobori as well. This lens is relatively modern compared to other Soligors.

Thanks. The bubbles are quite pleasing to me eyes. I am sure if used at a certain situation, the bubbles can be a nice part of the photo.
I somehow remember the Spiratone is slightly larger, but my memory could be wrong. I'll need to locate where my Spiratone is and make a comparison.

One thing I'd like to add is that this lens is sharp enough at close distance; but at longer distance, the sharpness seems to start to drop.

Not bad for close shots , contax users wouldn't have lots of cheap options on this focal , so third party could be worth it ,even though there was big compromise regarding image quality ,comparing zeiss or yashica lenses (don't remember yashica 20-21mm FL)

The Zeiss 20mm must have been insanely expensive. I don't know if the Yashica 21/3.5 was much cheaper, it's a very fine lens! I don't have anything to compare it's performance to except a Vivitar 20/3.8 (it kills that one) but so far I've been very happy with it.

Don't forget that many amateurs had C/Y cameras too... something such as the Yashica FX-D or the Contax 139 was surely not paired with the premium Zeiss glass. You might find those sets with the Zeiss 50's 28's or 135 and sometimes 25 but never any of the "extreme" focal lengths. So it must have made sense for 3rd party manufacturers such as soligor to offer a reasonably priced alternative.

Thanks very much for the comments. It makes perfect sense. I also have a C/Y mount Vivitar CF 28mm f/2. I guess it is for the similar reason.
