Review
The Orion 15 is a Russian-made 28mm wide-angle lens with an aperture of F6 and is known as a TOPOGON copy of ZEISS.
This individual was made at the ZOMZ factory from the bow-like markings.
There seem to be many old models of this lens in circulation, and many have worn-out aluminum barrels.
The lens I owned was also a worn-out lens with a sparse helicoid because I got it cheap.
The filter diameter is 40.5mm, and I would like to install it to protect the convex front element, but like the NEW RUSSAR+, if you install a filter, you will not be able to move the aperture, which is a disadvantage. Since it’s a cheap lens, I think it’s best to take advantage of it and use it without a filter, or use it as a fixed F lens since it’s dark at F6 even wide open.
The minimum focusing distance is 1m, which is the same as that of the Barnack type (Leica A/Leica I) Leica, and it’s a shame that you can’t get close enough with the lens alone.
As mentioned earlier, the lens was worn out, but it had no problems with the depiction and showed dramatic depictions in scenes where the surroundings were dropped. When photographing buildings, the symmetrical lens configuration is good because there is little distortion.
Perhaps it’s because the focal length is 28mm, or it’s better to stop down to F6, but I’m very grateful that the color cast is less noticeable with the Leica M typ240, where wider-angle 21mm class lenses such as Russarl and Super Angulon tend to cause color cast.
