Helios 44-2 58/2 Zebra

Helios 44-2 58/2 Zebra copy of Carl Zeiss Jena Biotar 58mm f/2.
The most complete information about the version of the Helios lens models, we can find at this link.
http://forum.mflenses.com/complete-list-of-helios-lenses-getting-closer-t26100.html
This model has a serial number beginning with the three zeros at on the basis of information from the link below: http://forum.mflenses.com/viewtopic.php?t=3332 suggests that this is a pre-production model.
According to the markings on the lens ( http://cameras.alfredklomp.com/logos/ ) has been produced in a factory MMZ : Minsk Mechanical Factory. Founded in 1957, MMZ was located in Minsk, Belarus, approximately 450 miles SW of Moscow.
In contrast to the previously tested by me Helios 44-2 (http://m42lens.blogspot.com/2013/07/helios-44-2-58mm-f2.html ), which have anti-reflective coatings in purple has antiglare coating in yellow.
The quality of the lens is higher than previously tested Helios Lens. Precision workmanship and quality of materials is noticeably better.
I noticed that all the Russian lens are heavily oiled the blades. This oil is so interesting about that never liquefy the lens. Not evaporated by heat embedding in the form of mist the lenses. It has another good feature. Makes the small pollens is not deposited on inside the lenses but is absorbed by the oil. I can boldly say that oiled the blades in Russian lenses is not disadvantage.
In the near future, let me do a test both lenses into account differences in the optical. Rating lens will take place after the testing.
