This time - a Zenit-S from 1956

    I bought this last week on a local online auction. The seller said the mirror didn't work.
    When it arrived, I found that the mirror glass was broken, in addition to the mirror not cocking, and the camera also lacked a takeup spool - It's a bottom loader, like a Zorki or a prewar Leica.

    I have the instructions to replace the mirror cord - the mirror is operated by a pulley arrangement. There was a cord in the camera, which didn't look original, and was not installed correctly. I replaced it with a length of linen cord.

    I found a mirror in my selection of camera parts. It wasn't as deep as the original, and needed packing to match the original's thickness, but it works. I need to adjust the mirror position, though, to get correct infinity focus.

    The infinity focus has been adjusted. The mirror position is changed by movement of the 2 screws, seen in front of the prism, here.

    You're beating it into a ploughshare?

    Seriously, it always amazes how anyone can happily grab a screwdriver and go diving this far into a camera's innards. Scares the daylights out of me.

    Going in is not a problem.

    I can second that! I was loony enough to try to learn on Prestor (not Prontor - Prestor!) shutters, and several patients died on the operating table before I got the hang. It's been a while now, I wouldn't be so confident today.

    I'm guessing that the Zenit is a relatively simple and well-documented shutter? It's certainly an interesting beast, you can see the Leica-copy (but which one? Zorki?) ancestry in the body shape with that mirror rather bolted on to the top.

    Yes, the Zenit is relatively simple - it's based on an early Zorki. Reputedly, the bottom cover will fit a prewar Leica. It's a surprisingly petite camera, the same length as a Pentax ME, and not as tall. Now what I need is a takeup spool, and I can try it with film. I have a collection of parts, from cameras I've scrapped, so I might see if there's a spool among them that will do the job.

    I have a takeup spool - Chris Sherlock gave me one, from a scrapped Leica. I had to grind a little off the end, for it to fit the Zenit. I loaded it with film, and tomorrow, I'll take it out shooting.

    He's a top bloke - I think more of my Retina II came out of his part bin than the camera I sent him!

    The second film I processed today was from the Zenit. Like the Praktiflex, this has a flary lens. It is capable of reasonable detail, though, if direct light is kept out of the field of view.

    I see what you mean - the difference is startling! I'm assuming it's an uncoated lens? Is it early enough to be the odd Zenit thread - what was it, 39mm, but a different pitch to LTM?

    Both this, and the Praktiflex lens are 50mm f3.5, both are coated. The Praktiflex lens is a Tessar, and the Zenit lens an Industar. The Industar has the same thread as a Leica, but the focal distance is different, to allow for the mirror box on the camera.

    Thanks - I knew there was a reason the early Zenit lenses were different, obviously hadn't remembered why!

    It all depends I suppose on what you are used to. I have no mechanical training what so ever but after several attempts I learned (taught myself) how to strip, down and repair motorcycle gearboxes. I have not done one for many years now but taken in a methodical way they are relatively quite simple.

    UNLIKE computers, I can work one - sort of - learning to use photoshop is an ongoing process, and repairing one is out of the question. Basically if it moves slowly I can generally fix it, electrons are moving to fast so I can't

    Cameras are straightforward enough to fix, so long as you recognise your limitations. I've learned by experience that lens shutters are best sent off to a repair technician. Focal plane shutter cameras, though, are more straightforward, especially ones as simple as this Zenit. Someone had already, at some stage, replaced the shutter curtains, and done a very nice job. The problem here was the mirror cord (and the mirror). I have a copy of Maizenberg's Russian camera repair book, which gives instructions on cord replacement - it looked like someone had a go at it without instructions, didn't pretension a spring, and used a length of knitting wool as a cord.
    I learned how to work on mechanical things back in the 1970s, when I trained as a telephone exchange technician - very useful training.

    If something isn't working and is of small cash value it can't really be made any worse by having a go.

    I've always liked the Cyrillic script on the older Russian cameras.

    It depends on what you call "small cash value". I paid nearly 50 pounds for this camera - almost anything this old has been rising in value for some time. The original Zenit model, the one before this, is on Ebay for very high asking prices.

    £50 is not now a huge sum of money to anybody who is buying cameras. To somebody who is homeless it is. A repairer will charge more than you paid for it to repair it anyway.

    Twenty years ago, I was able to buy unhappy film cameras - like a locked up Canon FT - for around 3 pounds...cameras like this have become fashionable. Doing my own repairs means I can save money.

    It can still be a fair amount of cash to someone interested in film cameras but on a very limited budget.

    Such a person would presumably go into this with no false illusions though.
