LOL I guess it's not only the leaking we have in common, also Zenit and Helios experience
Yups, this enlarger is built like a tank, not only from outside. I've just finished cleaning it throughly. Die-cast, crude and heavy, much like some Opemus enlargers I've seen, minus all the rounded edges. Russia is unlike any ordinary, civilized place, things there either are solid or borked.
It looks like I can mount some M39 lenses to the enlarger if I50U won't be up to the task. Not every one of them, cause there's very little space there (m42 thread won't fit the space designed for the lens, so it's less than 3mm of space), but still it leaves me with options like Nikon or Rodenstock lenses made for enlargers. I've visually checked image quality of the lens I have, and I guess it'll be sufficient to at least seriously try to work with this tool. The image is sharp and contrasty, the lens and timer are easy to use, the condenser seems to be working fine, and the enlarger itself is pretty stable thanks to its weight. All I need to start with.
We have three Zenit bodies here (E, 12XP and 3M). One I borrowed, one belongs to my GF and one I keep for sentimental reasons only. I can't stand their tiny viewfinders, no-go for a tool one has to work with. Plain, ground glass, 20x30mm size at best. Especially if you can replace it with any other semi-decent camera, there's just no coming back. But all three are in working condition. The curtain shutter in FSU 35mm cameras won't break easily BTW, it's derived from pre-war Leicas - doesn't matter if it's FED, Zorki or Zenit, it originates from Leica II. It gets used, either ribbons, curtains or glue will finally give up, but it's a matter of proper maintenance to prevent it from happening.
Also Helios originates from pre-war Germany - Zeiss called it Biotar back then. 44m is an excellent design, Russian engineers were perfecting it for over 60 years, and you just have to love the swirly bokeh it gives
Actually a different Helios (103) is regarded as one of the best lenses for Kiev/Contax rangefinders. I've had Kiev 4AM with this lens, and I must say the body was inferior. Heavy like a brick, I was unable to nail framing in vertical direction, and it suffered from uneven film transport. On the contrary, the lens was pure magic, Ive done my best photos with it. I've sold it long time ago. Best, apparently, is not good enough. I'd give all but one film cameras, filters and lenses I have for an old Contax II with two lenses and two filters (Helios mentioned above and any decent backup lens plus polarizer and pale yellow-green filter), but I'm afraid the world just won't work this way.
I've been working with Z-1 for a short while, disliked the experience, and it was left unused ever since. I won't regret selling it, really. It's a pity to see such a decent camera gathering dust in a dark corner just because me being not flexible enough. But I am what I am, I can't work with it the way I like. So I don't. It should capture light, enable someone to make brilliant photos. Cheap Ricoh bodies in K mount have better viewfinders (bigger coverage and magnification) and some of them will never complain about depleted batteries. And this is more or less what I value, getting the job done without any distraction. I guess I'm Zorki/Leica type of guy, a lost case anyway.
I'll keep tri x and pyro in mind and try it as soon as I'll run out of Polypan, thanks a bunch for the tip
I've never worked with pyro developers, and I recall I've done only like one or two rolls of any b&W kodak film, apart from Accademy, years ago. I was working more with Foma and Ilford films. I don't mind toxicity, pyrogallol is noting compared to dichromate anyways.
Beware, Polish is one of hardest languages to master. A lifetime task, even for some native speakers
