I recently bought a second hand Horizon 202 (in Russian: "горизонт") panoramic camera. Originally I wanted something more reliable such as Noblex or Widelux, but got a chance to get a Horizon 202 for a price you can't even dream of with the latter cameras, and went for it. Although Soviet times are over and it's now "independent" Russia the basic design of this camera is still from the Soviet era and work ethics remain similar in production. I've had horror stories with Soviet cameras (pain-in-the-butt Kiev 60 to be specific) so wasn't particularly comfortable buying it, but since it was experimental field to try for me, I made the choice.
Not being a big fan of small 35mm (135 roll-) film format so it was an odd choice for me, but it's different from a regular 35mm camera - Horizon 202 gives you a long 24 x 58 mm frame, a decent area for some improved tonality. The wide-angle multi-coated 28mm f2.8 lens it houses proved to be state-of-the-art killer-sharp (in the usually poor-quality Soviet lens standard at least!), truly a gem lens - once you stop it down beyond f11 it's literally clinically sharp - I before said my Fujinon Super-EBC lens on the GA645i is sharp - well, Horizon's tiny Russian lens smokes this excellent Japanese lens! The lens acts like large-format lens that is optimized for small apertures, so the payoff is it's rather soft on large apertures, the f2.8 - f5.6 range. I've heard the later Horizon S3Pro camera, that hosts very similar mechanics to 202 model, but has it's lens optimized for also bigger apertures, yet similar payoff seems to be the users say it's not as clinically sharp on small apertures as the 202 model lens. You can't have all, it's a compromised win-lose situation with this particular lens and you need to learn it's weaknesses and strengths like with most lenses.
