piblondin Posted January 15, 2012 Share #1 Posted January 15, 2012 Advertisement (gone after registration) Can someone post an image of that the M7 baseplate with the additional washer to support the optical DX reader looks like? I'm trying to determine if mine has the washer. Does it matter? I do have the optical reader. Thanks! Link to post Share on other sites More sharing options...

piblondin Posted January 15, 2012 Author Share #3 Posted January 15, 2012 Thanks! Is it necessary that I have this if I manually set the ISO? Is there anywhere I could buy the screw + washer? DAG? Sherry? Link to post Share on other sites More sharing options...
Guest sterlinstarlin Posted January 15, 2012 Share #4 Posted January 15, 2012 My .58 M7 has the old optical reader and I haven't had any trouble. I usually set my film speed manually. I've never had any trouble removing cassettes either. My camera has the original viewfinder too, and I've never had an issue with flare. The M7 is a great camera.

piblondin Posted January 15, 2012 Author Share #5 Posted January 15, 2012 To clarifiy, what I meant is: Is it okay to use the old baseplate without the washer with the new optical DX reader? Or will I have problems with the ISO? Link to post Share on other sites More sharing options...
Falstaff Posted January 15, 2012 Share #6 Posted January 15, 2012 Thanks! Is it necessary that I have this if I manually set the ISO? Is there anywhere I could buy the screw + washer? DAG? Sherry? Mine was still misbehaving despite my setting the ISO manually. I'd send it and get the proper modification done. Falstaff Link to post Share on other sites More sharing options...

I'd say it is a fair chance that Leica NJ would be able to supply you too. That said I've never asked Don for a part such as these he hasn't had readily available. Send an email and ask.

}{B Posted January 17, 2012 Share #8 Posted January 17, 2012 I bought a used M7 in August last year. It came with the two years of warranty left and although it had the upgraded viewfinder it still had the mechanical DX system. I returned it it to the dealer in October to have it upgraded with the optical DX system and it was returned from Solms in November. I've only just used it again this last week and although the first roll of film went through without problems I started getting a flashing shutter speed of 1000 sec at all apertures with the second roll of film. I've changed the batteries and checked what film speed is showing in the viewfinder when the fault occurs. With the camera set to auto and on DX it shows a film speed of 1600 when it should be 100 ISO. Setting the film speed manually restores the correct shutter speeds in auto mode. Looking at the baseplate it appears that Leica fitted the new washer when it was with them for the DX conversion. I was hoping that that this would not be the case and it would therefore be a simple problem to fix. Has anyone else had a similar problem with and M7 with the optical reader and fitted with the new washer ? I've not been able to find reference to a flashing shutter speed of 1000 in the cameras manual. Link to post Share on other sites More sharing options...

Carl Leica NJ will probably send you just about anything. I had a pressure plate that was scratching film. I didn't what to send my camera in, so I had Leica send me a new pressure plate. They sent it free of charge with instructions. I'd contact them. Link to post Share on other sites More sharing options...
wattsy Posted January 17, 2012 Share #10 Posted January 17, 2012 ...I've changed the batteries and checked what film speed is showing in the viewfinder when the fault occurs.

Setting the film speed manually restores the correct shutter speeds in auto mode....I've not been able to find reference to a flashing shutter speed of 1000 in the cameras manual. It's been a few years since I owned an M7 but doesn't a flashing 1/1000 simply indicate potential overexposure - i.e. the camera is telling you that it doesn't have a shutter speed fast enough to make a 'correct' exposure for the set aperture. This sounds consistent with the camera thinking the film speed is ISO 1600 rather than the intended ISO 100. Unless I'm misunderstanding what you are asking, it simply sounds like your camera's DX function may not be working correctly and might need to be looked at again by Leica. FWIW I had a very similar problem with my first M7 (which had the old mechanical DX reader) so it may be that this kind of problem is not directly attributable to the DX reader itself but to a problem in the electronics elsewhere?

}{B Posted January 17, 2012 Share #11 Posted January 17, 2012 Thanks for the reply. I believe you are right about over exposure. The DX was reading the film as being 1600 speed rather than 100 so this would explain it. However it still means that the optical DX system was misreading the coding on the film. After some thought I've come up with a possible solution. As I mentioned one roll went through the camera perfectly last week when the weather was milder than it has been for the last two days. I started having this problem when I loaded a second film yesterday when the outside air temperature had dropped to 1 or 2 degrees C. I noticed today that outdoors the back of the camera became covered in condensation as it rested flat against my body. The flashing 1000 problem has occured on two consecutive days when the outside air temperature has been just above zero on each day and has occured within minutes of removing the camera from the camera bag and exposing it to the cold air. Could it be condensation in the film cassette chamber fogging up the IR transmitters and effecting the reading? To test this I've loading another film in the camera and with the camera set to auto and DX have taken a meter reading through the window while the camera is at room temperature. The problem did not occur. The outside air temperature is set to rise during the next few days and so I propose to test this theory more fully by shooting off an old roll which is past its date just to see what happens at higher air temperatures. At the moment air temperature and condensation is all I can put the problem down to. Link to post Share on other sites More sharing options...
Guest Digiuser Posted January 17, 2012 Share #12 Posted January 17, 2012 To clarifiy, what I meant is: Is it okay to use the old baseplate without the washer with the new optical DX reader? Or will I have problems with the ISO? You can also use the old baseplate but in very few cases you can get a misreading depending on the kind of dx coding on the film canister which has also tolerances from brand to brand. If you have problems with your film brand, you can get the washer and the longer screw from the customer service. The change can be done in one minute.
