          yep, Yashicas flares looks less natural to me. But they have very cool purple-violet soft gradient flare. Sometimes, if there is no direct point of light in the frame, it looks similar to anamorphic )
          Also when you rotate focus ring on Zoom lens (which usually have rotating front lenses elements), the flares shape is changing. Its like two different flare layers blended one to another.

            Here are also a few photos of disassembled lens. Useful if someone decide clean the helicoid on same lens. Actually those photos from older OKS, but main structure is almost the same. Also suggested don't unscrew lens module from the main body until you really need this.

              Today my RafCamera Kinor-16SX-2 to MFT adapter with screws arrived. I got it for free from Rafael of RafCamera, because the bayonet lock version didn't fit my LOMO 16 OKS 3-10-1 f/2.1 10 mm. But the simpler version with screws fits as a glove! The lens is fastened securily with three allen screws, using the attached allen key. Rafael explained to me that the bayonet lock version isn't a adapter who fit all 16 OKS prime lenses, as it has a removable back which may be adjusted with three screws. Simpler version is safer for use with the OKS primes (and possible for OPF zooms) since it has longer inner space due to absence of the removable back. RafCamera is really a realible company who cares about its customers, giving support beyond what can be expected. And I won't hesitate to buy a whole set of adapters if necessary to fit my future OKS primes set.

              16 OKS 3-10-1 f2.1 10 mm,.jpg

              There were still some residues from the anodising black lacquer which rubbed off on my fingers, so I had to clean and polish the adapter with household toilet paper and some linen cloth before I could attach it to the lens. It has two grooves to chose from, when inserting the lens to the adapter; I choose the one which makes all important information on the barrel visible from above. When mounted to the MFT mount of the BMPCC, the flaps (thumb grip) of the focus ring goes all the way around the barrel, underneath it, which would make it ankward to use it when applied to a base plate with 15 mm rods. I will buy some kind of follow focus gear ring for the lens in the future. But the most important thing is that I now can see a image from the lens looking at the screen, so the flange distance seems to be o.k. from what I can see. I will take some shots with the lens in the weekend to see if focus is optimal, but everything looks ok right now. However, the lens, being a 10mm, vignettes quite heavily on both sides (not just the corners) and there is obvious barrel distortion (but that should be expected from a 10mm lens); it almost looks like a fish-eye. But the viewing angle is great, giving opportunity to take very wide shots. Either cropping 2.40:1 or zooming in post, or both, will do the trick with the vignetting.

                Thomas, a 10mm lens for 16mm or S16 should not have heavy barrel distortion. The SLR Magic MFT lens distortion is very well controlled, as is the 9.5mm Super Speed S16 lens. But putting a std.16mm lens on the Pocket camera is going to bring out all the edge defects, not meant to be included in the film gate frame. My Russian made Optica Elite 9.5m. Even covers the BM Micro 4K sensor (which is a little larger than the Pocket camera sensor).

                Either yiurmlens has a small projected image circle, or the FFD for the adapter is off. See if you can focus to inf, if not the FFD is lol long, which would reduce your lens' projected image circle.

                  Thank's for the tip. It seems that infinity focus is found before the infinity symbol hits the mark, rather somewhere at 1 m. When I push focus beyond 1 m the image loose focus again. I checked the lens with my Kinor-16 and here infinity was corresponding with the infinity symbol. May this be a sign that the FFD is to far off on the adapter?

                    Its ok, my 15 mm OKS lens also don't fits into focusing marks. Wider lenses needs more precise shimming. Try to add 0.1mm or thiner shims from foil or Oracal tape.
                    Also you can declick this lens by unscrewing rear coil element which holds two small metal balls and springs. This also helps to fit 10 and 15 mm lenses to Rafcamera bayonet adapter. See the photo in first post.

                      I undscrewed the thee allen srews which holds the lens in place inside the adapter, and pushed it out just a tiny bit, perhaps one milimetre or so, or less. But the focus was entirely off; I could only focus up to a couple of metres from the lens. So, perhaps the problem is that the flange distance is to long after all.

                        1mm is too large shim. try 0.1mm or smaller. this makes real difference.

                        To declick aperture on 10 and 15mm OKS lenses Unscrew this ring and remove two small balls and springs. On other OKS lenses unscrew one small screw in front of the lens and remove small ball and spring.

                              lens Spanner Wrench tool or something similar like filter unscrewing tool. This ring is very thin and usually easy to unscrew.
