iDon Posted March 14, 2017 Share #1 Posted March 14, 2017 Advertisement (gone after registration) 2 questions for the R community: I have an APO-Macro Elmarit 100 which returned yesterday from repair because of sticky aperture blades. Now it seems to work properly, but if I move the aperture lever of the lens i still feel a bit more tension compared to my other R lens whose aperture lever moves more freely. With the camera (R7) it seems to work normally. I've tried to fire the shutter with 1/2000th and look through the shutter and I the aperture is closed. Could anyone check his/her lenses if there are differences between them when it comes to aperture resistance? Is it normal or do I have to send it back to the repair guy? While I tested it, I notized, that my R7 does not close the aperture further than f16 during exposure, only by pressing the DOF lever. I had the camera in B mode and the lens fully closed at f22 and during exposure the aperture was closed only at f16, but stayed at f22 when I pressed the DOF lever or when I turned the aperture ring from f22 to f16 and back. I've read that this would be a common problem of the R4-R7 series and could be repaired by opening the baseplate and cleaning the aperture release mechanism, but couldn't find more information about it. Do you think it is a problem of the lens (my other lens only has f16) or of the camera? Does anyone know how to fix it, if it's a camera problem?Thanks!

jip Posted March 28, 2017 Share #2 Posted March 28, 2017 The problem of the not reaching F22 is a problem with the camera most likely, the higher tension I don't know... my R lenses all feel different to be honest. 1 Quote Link to post Share on other sites More sharing options...
SilentShutter Posted March 28, 2017 Share #3 Posted March 28, 2017 The guy asked the same at the german forum. Lens was send back to service. Problem solved. Quote Link to post Share on other sites More sharing options...
jip Posted March 28, 2017 Share #4 Posted March 28, 2017 How can it be that the aperture closes with the aperture preview lever but not when taking an image, that means it's a camera related problem not lens related problem. 1 Quote Link to post Share on other sites More sharing options...
masjah Posted March 28, 2017 Share #5 Posted March 28, 2017 How can it be that the aperture closes with the aperture preview lever but not when taking an image, that means it's a camera related problem not lens related problem. I suspect that it's because the aperture preview lever is a rigid motion that will overcome any stickiness in the lens diaphragm mechanism, whereas the stop-down mechanism when taking an exposure is more dynamic and the lens's stickiness may be capable of holding it back. I once had a somewhat similar problem when I first bought my ex-demo 100/2.8 macro, and the lens's mechanism needed a bit of sorting (which the then Leica UK at Milton Keynes sorted within a day or two).

(Neither do I for that matter.) Surely if you don't understand something, it's hardly unreasonable to pose a "how or why" question? Quote Link to post Share on other sites More sharing options...
SilentShutter Posted March 29, 2017 Share #8 Posted March 29, 2017 John - thats why I posted that the problem was "solved" and the lens was the reason. By the way jip is dutch and the most of them speak or even understand german. 1 Quote Link to post Share on other sites More sharing options...
jip Posted March 31, 2017 Share #9 Posted March 31, 2017 You can test if it's the lens by actuating the lever at the back of the lens slowly with little force, you'd feel the increase in force needed from f/16 and further. The R8/R9 have more force when stopping down the lenses so maybe on these cameras it wouldn't even be a problem. (They stop down faster with more force than the older R's) Quote Link to post Share on other sites More sharing options...
SilentShutter Posted April 3, 2017 Share #10 Posted April 3, 2017 I agree jip a little force from time to time help things cooperate or like my grandmother used to say: "Fang es in der Kammer und erschlag es mit dem Hammer !!" Quote Link to post Share on other sites More sharing options...
