kenneth Posted September 25, 2008 Share #1 Posted September 25, 2008 Advertisement (gone after registration) I am curious to know what the small 5mm round disc is at lower right as you look through the body from the front without a lens mounted. I could not find an example M6 picture to show what I was referring to but I have enclosed a picture of an MP which shows it clearly just inside the lens flange bottom right Welcome, dear visitor!

veraikon Posted September 25, 2008 Share #2 Posted September 25, 2008 yes it the "sensor" for the rangefinder . Quote Link to post Share on other sites More sharing options...
gyoung Posted September 25, 2008 Share #3 Posted September 25, 2008 yes it the "sensor" for the rangefinder . lightmeter surely? Gerry Quote Link to post Share on other sites More sharing options...
kenneth Posted September 26, 2008 Author Share #4 Posted September 26, 2008 Well that is 2 thoughts on what it might be. Do we have a diviniative please? Quote Link to post Share on other sites More sharing options...
alifie Posted September 26, 2008 Share #5 Posted September 26, 2008 It is removed to gain access to one of the screws holding something on the top plate on, the rangefinder I think. You poke a long screwdriver through it from the bottom. Quote Link to post Share on other sites More sharing options...
wizard Posted September 26, 2008 Share #6 Posted September 26, 2008 Neither lightmeter nor rangefinder "sensor", surely. This is a simple flat plastic cap covering a hole. Alfie's explanation sounds good enough for me. Andy Quote Link to post Share on other sites More sharing options...
kodaktrix Posted September 26, 2008 Share #7 Posted September 26, 2008 Advertisement (gone after registration) This is a screw that covers a hole to have straight access with a screwdriver to the main screw of the rangefinder arm.

alifie Posted September 26, 2008 Share #9 Posted September 26, 2008 One of the many wonderful things about M and Barnack Leicas is that they are possibly the simplest 35mm cameras to take apart and fix. Everything is screwed together with real (not pozidrive/philips) screws, OK it can get a bit fiddly with things like rangefinder masks, but it is all doable by the average handy person. I think the worst things are the old lens diaphragms, it took me an hour to re-assemble one of those once, I would love to see the Leitz jig used to build them in the first place. I don't know what happened but you could not get spares from Leica UK a while ago but you can now, is this some EU ruling on restrictive practices?

andybarton Posted September 26, 2008 Share #10 Posted September 26, 2008 IF things go to plan, I may be taking apart two duff R8s in a couple of weeks and seeing if I can make one good one out of them... Quote Link to post Share on other sites More sharing options...
pleeson Posted September 26, 2008 Share #11 Posted September 26, 2008 IF things go to plan, I may be taking apart two duff R8s in a couple of weeks and seeing if I can make one good one out of them... A few pictures of your efforts would be cool. I'll bet you can pull it off; and what's to lose?? Maybe they're both capable of resuscitation... Good Luck!

Re tampering reminds me of a little story I might relate- Many years ago, when I used to imbibe of the dreaded liquor, I gave up 18 years ago due to over-dependence, I had a pair of Leitz Trinovid 10x 42 Binoculars that had a small speck of black lining coating on the inner lens. Well after a few too many beers, I decided it could not be difficult to take them apart and remove the offending speck. I duly got to work with a jewelers screwdriver when suddenly, there were springs everywhere. Needless to say I had no hope of re assembling the binoculars so I took them into an authorised dealer in Harrogate who returned them to Leitz. The resulting re build cost me £180.00- 1983 prices. So let this serve as a cautionary tale to anyone who believes that Leica equipment is easily D-I-Yd. Or at least, approach the work sober with a clear head Quote Link to post Share on other sites More sharing options...
rob_x2004 Posted September 27, 2008 Share #13 Posted September 27, 2008 If you hadnt stripped them down ready for the tech, it would probably have cost you two hundred and eighty pounds:o. Quote Link to post Share on other sites More sharing options...

jhild Posted September 28, 2008 Share #15 Posted September 28, 2008 That little cap is the same on all M Leicas, it´s plastic on the MP and metal on the earlier ones. It can be pushed out from the bottom of the camera if it´s plastic, the older metal ones have something like a bayonett and have to be turned to get them out of the way. The hole gives access to one of the three screws holding the rangefinder in place, the other two are in the film chamber. The second reason for the hole is giving access to the excenter adjusting the randefinder feelerarm´s lenght. Jo Quote Link to post Share on other sites More sharing options...

marknorton Posted September 28, 2008 Share #18 Posted September 28, 2008 The M8 has the same thing, a small plastic/rubber "widget" which is removed to allow adjustment of the rangefinder using a long screwdriver. Quote Link to post Share on other sites More sharing options...
tobey bilek Posted September 29, 2008 Share #19 Posted September 29, 2008 The plug is removed to acess the rangefinder horizontal adjustment with a straight screwdriver so you need not butcher the screws doing it from the lens mount . Quote Link to post Share on other sites More sharing options...
cmatter Posted September 29, 2008 Share #20 Posted September 29, 2008 Hmmm.. was never aware of this. Interesting. I looked inside my M-2's; and, sure enough there's one there, too. Just a lot less noticeable. Curious, though. Mine look totally pristine.. like they've never been removed. Wondering if I should infer this to mean that my rangefinders have never been adjusted??
