<p>I recently purchased a 500C/M kit from a trusted eBay seller. It was CLA'd by him and then sold to me. I put a roll of Tri-X through it and got it developed. To my dismay, none of the photos came out at all. A few had bright spots in one corner, but all of them were underexposed greatly. These were shot at small apertures and high shutter speeds as they were taken on a sunny day with 400 speed film.<br /> <br /> Before the first roll was developed, I started on a 2nd roll. I got the call about the failed roll while I was half way through my 2nd roll. I finished the roll quickly to see if maybe I didn't load the film properly or just wasn't using the camera right, but when the 2nd roll got developed, 3 pictures came out and the one that looked normally exposed with no issues was a shot taken at f5.6 and 1/30".</p> <p><br /> Since then, I've been doing tests to see if I could isolate the problem and what I'm seeing is that at higher shutter speeds, sometimes the shutter isn't opening.</p> <p><br /> My test was done with the lens set at 1/500" and f2.8 on self timer so I could record the actuation in slow motion. The first video is what I believe is the camera operating normally. The second video, you can see the shutter moving slightly, but not nearly enough to let any light in.</p> <p>My question is this: If this lens was CLA'd, is there anything simple to check by opening up the front or back of it? The guy I bought it from is on vacation for 2 weeks and I'd rather not have an expensive paper weight for that long.<br /> Thanks, Tom</p> <p>http://vid86.photobucket.com/albums/k94/gtxtom/pass_zpsoirjpvwy.mp4<br />http://vid86.photobucket.com/albums/k94/gtxtom/fail_zpsjsnqcchr.mp4</p> <p><img src="http://i86.photobucket.com/albums/k94/gtxtom/DSC_0141-2_zps4mxr6qag.jpg" alt="" /></p> <p> </p>
