Soligor 21mm f/3.8

[StephanN]

My workhorse for wide-angle landscapes, the Soligor 21mm f/3.8 in M42-mount. I've used it for the photos in these threads: https://www.ultravioletphotography.com/content/index.php/topic/4167-mauthausen-in-uv/page__fromsearch__1 , https://www.ultravioletphotography.com/content/index.php/topic/3997-university-architecture-uv-ir-700-nm/page__fromsearch__1 , https://www.ultravioletphotography.com/content/index.php/topic/4037-eisenstadt-in-uv-vis-ir/page__fromsearch__1.

The pictures you have taken with this lens are quite good. It is in the same class as the Tamron and Asahi offerings; I wonder how it stacks up in absolute terms.

The Panagor 21mm f/4 lens is probably another knock-off, or rebranding, of the Soligor. I found it quite useful for UV not the least due to its very close focusing capacities. Using my DIY rear-filtration device for the Z cameras, it will focus almost to the surface of the front lens yet still go to infinity.

If you can focus that close, can you use it for macro work (maybe at low magnification)?

Actually that's what I mainly did. However, I hesitate to misapply the term "macro" in this scenario.

Thanks. Hm, have never done a scientific test, perhaps Birna has done so with her Panagor?

It looks similar, judging from one can find on the internet. In fact, I believe that there has been so much of rebranding with these older lenses that one can hardly be sure of anything; actually it is still going on with theses Samyang/Walimex/Rokinon/Bower-lenses

See here: https://www.ultravioletphotography.com/content/index.php/topic/4451-bushnell-21mm-f38-automatic/ for a proper test by Ulf (Bushnell is just a different name for the rose). It's not going too low, reaches zero transmission around 350, but the image quality is ok for me.

I recently bought a Soligor 21mm f/3.8 off eBay.  I had a moment of bewilderment when I tried to screw in a 72-77 step-up ring.  It turned out that the thread was 67mm.  So I googled.  Everywhere I looked said the thread should be 72mm.  The following are some pictures of the lens.  The front and rear caps have stickers of "21mm T3.8" on them.  The inside rim of the front cap has a narrow tape of some thickness that maintains contact with the filter mount, which can be unscrewed from the lens proper.  Perhaps this is a variety for video.  Or is it a fake?  Thank you.

It’s hard to imagine it would be worth building fake Soligors, which sounds almost redundant :  ).  
 

Closed eBay item #313924610513 looks the same as your lens.

Yes, it's similar to what I got.  Thank you.
