A real low-tech part of Belarus, it consists of solid iron and Glass. So, no motors, no gold contacts, no CPU, and therefore no firmware updates :-). For the Russian manual I have found the happiness in the Internet a translation. The lens is built very sturdy and the workmanship is good in my opinion.
It is to my knowledge only through ebay from the East or from the U.S., and costs only a fraction of the brand lenses of similar focal length, but no automatics. It is the focused manually. And the panel must be set manually on the condition that this "activated" even with a third adjustment, otherwise it remains open.
However, there is a shortcut: the part has allegedly Aperture f / 8 its best image quality, I would say preferably work with this panel (play). And at f / 8 and 8mm focal length is one of just 43cm Hyperfokaldistanz, that is, from this distance, everything is sharp.
Conclusion: I will cover 8 and set the focus to touch on a few meters and the rings any more. I just have ISO and exposure time for each set the camera on light conditions, and that should be the best method of trial and error to create.
will in the near future so I play a bit and publish any demonstrable results here.
