<p>Hello all. I took my 1.4 apart to clean it. It had oily blades and a haze that was producing low-contract images.<br> Everything seemed to go well. I got the aperture housing out, front and rear lens elements off and they cleaned up well. I almost declared myself a superhero, when I tried to put it back together :-)<br> Everything went into place until I got to the rear mount. There just doesn't seem to be the right spacing for the AE pin, the stop down link and the aperture selector to all go where they need to go.<br> I could put up a link to a video, but thought I would check for any troubleshooting suggestions first.<br> Thank you!<br> Joe</p>
