Zenit was a good school. I have been using it for the lo-o-ong years to fix the surrounding reality and wasn't really caring about saving results.

I have some of my pictures of that times left in family albums, you can see the example (UT18 slide film, scanned on Nikon Coolscan IV).

I have been shooting mostly BW negatives and color slides; in 1981 I bought 135mm F:3.5 "Jupiter 37A" lens, then, when it drowned in river Berezaika (spring 1982), I bought the lens again. My first telephoto, it was good.
