<p>I recently purchased a ETRS "kit" from KEH and it all arrived nicely packed and fine. I have installed a new battery (the check light works fine), the prism is metering correctly, the lens looks great and the film back winds forward and stops on 1 when theres film in it. The problem comes when I try to take a picture, I have the darkslide removed and I've went the checklist in the manual 3 or 4 times, but when I advance everything the shutter button becomes easy to press but it just bottoms out and nothing happens, the shutter isn't firing, the mirror doesnt move, and the advance lever doesn't unlock. It also doesn't act any differently in multiple exposure mode. It winds to a stop and then won't fire. I don't know the system well enough to really troubleshoot what it could be, so I'm not sure if its an error on my part or if theres a problem with the body of the camera its self. </p>
