Default Russian Cold War Optics

A Russian manufacturer now known as LOMO is renown for it's current line of optics. The camera lenses it made during the Cold War were also of the finest quality and very robust as well. I was fortunate enough to find one for sale. It is a 1000mm f10 reflex and has no "made in ____" which makes it a military version. It is the best long telephoto I have ever come across. Attached are two images taken from ~40' away. The first is full frame and the second is a 100% crop of it. Note the total absence of C.A. and the sharpness of the very flat field. It Takes some getting used to when focusing but that is the only con.
It has the standard Pentax style M42 screw mount and adapters to most SLR's are easily found.

Catadioptric ("Reflex") lenses are notable for their low chromatic aberration because their design requires very little refraction, which is the source of CA. Conversely, conventional "Refractive" lenses do a lot of refracting (duh), which causes different frequencies (colors) of light to focus at different distances, resulting in CA.

Also, catadioptric lenses contain few polished surfaces, so they are often very sharp.

Plus, they're small, light, and inexpensive.

The penalties are the fixed aperture and the goofy bokeh.

Congratulations on your find, but perhaps a 100% crop of a reflection was not the best way to demonstrate its sharpness.

You are right about the 100% crop, Tcav. I wish that I had taken the shot in RAW so I could have processed out the noise.
