    Hello all,

    New to the forum here and enjoying the content! I recently inherited some LTM lenses (35mm, 50mm and 90mm). I've been using them on my Sony NEX, however they made me really want to get back into film. I purchased a Canon 7 rangefinder of the web. The seller listed it as untested, but indicated that the shutter speeds seem to be accurate and the rangefinder was properly set. For $100 USD, I decided it was worth the gamble. However, upon testing, of course I realized a few problems:

    1. see the picture below. I feel like this is a problem with the film not advancing, as the statue is meant to be centered in the frame:
      issue-1.jpg
    2. Typically about halfway through the roll, the exposure counter stops advancing. It turns halfway to the next frame, then clicks back.

    I feel like the take up spool is not working properly. It's really difficult to load as the little tab in the spool that catches the sprocket hole doesn't seem to grab the film properly. Is it possible that it is losing it's grip halfway through the roll and the extra slack is not allowing the film to advance?

    I've never seen a problem like this before, as I've used a Nikon FM2N for about 20 years and never had any problems so I have nothing to compare it to. Any ideas? Is it worth repairing if it's anything major?

    Thanks!

    Good Evening, RallyFan,

    It could be a problem with the focal plane shutter. Wild thought: Any chance this was shot with on-camera flash? This looks somewhat like a flash shot made at faster-than-sync speed, although the complete lack of detail in the upper portion of the picture isn't typical of that problem.

    Konical - This was not shot with flash (doesn't even have a hotshoe!). A little more than half of the pictures came out properly, and a handful ended up like this.

    I'm really hoping this is salvageable, I love the size, viewfinder, and the fact it gives me both 35mm and 50mm framelines. Otherwise, I may have to bite the bullet and get a Leica III.

    Good Evening Again, RallyFan,

    I can't think of anything besides a malfunctioning focal-plane shutter. You might test at various speeds to see if the results are constant.

    It looks like a combination of shutter curtain hang-up and film advance malfunction. My answer is Essex Camera http://www.essexcamera.com/

    Thanks everyone. KLH lists a repair fee of $205, so it looks like I'll be packing it up and returning it. That would put me at $305 for a working Canon 7, which seems a bit high to me.

    Which Sony nex do you have? I am interested in getting one. You are able to use the LTM lenses on the camera?
    Thanks

    I have the 5n, which I got when the 5r came out. Only paid $349 for the body. The beauty of it is that you can adapt just about any lens ever made to it. For the LTM, I actually have the bayonet adapter with the LTM to bayonet on top of it. It was actually cheaper that way. Adapting lenses like Leica is great because it doesn't really increase the size much. The Nikon adapter, on the other hand, is rather large. And people always look twice when they see a new camera with a 63 year old Leica 5cm attached.

    Also, the image quality is very impressive (it's a version of the Nikon D7000 sensor). I believe Sony used a weak AA filter as the sharpness is amazing (seriously, read the reviews!). Additionally, low light quality is very good. ISO 1600 has minimal noise, and 3200 and 6400 are easily cleaned up in Lightroom. Also, for manual focus lenses, it has a nifty 'focus peaking' feature, along with the ability to zoom in to fine tune focusing.

    I picked it up after researching using legacy glass, like the LTM lenses. I love if for it's portability, it really makes me want to take it more places where my DSLR was cumbersome. And I'm extremely satisfied with the IQ. The only drawback for me is that the controls are not as intuitive as a SLR (or a rangefinder), but you get used to them. I highly recommend checking one out.

    Do you have a sacrificial roll that you can wind all the way to the end with the camera back open to see what is happening? I had a camera that was tearing sprockets half way through the roll and it turned out the rewind knob was just too stiff. A tiny drop of oil solved it.

    I did buy a few rolls of expired film for cheap and ran it through the camera both with the back open, and with the lens off so I could watch the shutter. Tried all the different speeds and didn't notice anything out of the ordinary. I might try it again a few times.

    You're probably right, but at the same time a local dealer has a freshly CLA'd Leica IIIf for $300, with 6 months warranty. I know all the quirks of using a Barnack camera, and I don't mind. Just figured if I'm going to go $300, might as well give my screws their proper socket. Of course, then I'll need a 35mm viewfinder...
