Kiev Arsat 250mm f/3.5

This is the Jupiter 36b renamed Arsat in recent years but otherwise unchanged. It is a superb lens for the price although its weight is crippling if you're lugging a selection of arsenal lenses around for the day.
It is very sharp, with good contrast and I sometimes use it with an adapter on my Zenit TTL, with excellent results.
I have had some badly assembled lenses from Arsenal factory, but this was fine and needed no adjustments. Recomended.
The Kiev 60 & its lenses are an excelent introduction to system medium format photography. I'm no beginner but i use this camera, and the Salyut-S a lot.

Cheap and excelent quality.
comes with sunhood and 3 filters in a leather case.

Heavey
no tripod mount on lens

All the Kiev 60 and Pentacon 6 lenses

Arsenal gives good service and cheap. I don't know about dealers abroad.

Finding a used one in a good shape is hard, but if you find one, get it. Images are sharp and contrasty. A bit on the heavy side with no tripod support, but I managed to hold it and the camera up on a piece of wood attached to my tripod - problem solved! It has a reversing built-in screwmount shade. Not bad, but mounting filters on it is a bit difficult as the aluminum or brass filters don't interact well with the metal hood and sometimes get stuck. I use this lens with an Arsat 2x converter and an adaptor hooked onto my Canon A1 more often than I do my Sigma 400/4.5 APO lens.

- Sharp lens - With adapters you can mount it on a lot of MF and tons of 35mm cameras - Clever case/hood design making it compact

- Heavy - 82mm filter ring - Hard to find a good one used - NO tripod mount - Aparture blades could be a bit more uniform
