Nimrod 0 Posted April 26, 2011 Were can i buy one of these needle valves for my IQ511 F-stop ring, the original is lost. I tried one from my lawn mower carburetor but it did not fit, item 12. Share this post Link to post Share on other sites
Soundy 1 Posted April 26, 2011 It's a locking screw, not a needle valve... and it's a part of the lens, not the camera. Other than taking one off another lens or ordering one from the lens manufacturer, your best option would be to simply replace the lens... IF it's actually a problem. It's not something that will normally go out of adjustment on its own, and frankly, you'll probably be fine without it. Share this post Link to post Share on other sites
