Gavbo Posted February 22, 2020 Share #1 Posted February 22, 2020 (edited) Advertisement (gone after registration) By chance I came across a m6 ISO back door listing, does anyone know if it is interchangeable with the MP with working ASA input? Always prefer the m6 ISO/ASA back door. Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members!

Advertisement Posted February 22, 2020 Posted February 22, 2020 Hi Gavbo, Take a look here Does m6 ISO door interchangeable with MP?. I'm sure you'll find what you were looking for!
a.noctilux Posted February 22, 2020 Share #2 Posted February 22, 2020 Yes, it works. I swapped them (for fun 😏 or to learn with some other swappings of doors and base plates between Ms ) for a while . the leatherette may not be the same, if that doesn't bother you. On the first MP for some years, they share the M6 style door with matching leatherette. In the picture, I see some cleaning marks on pressure plate, or just better clean it, those may scratch film Quote Link to post Share on other sites More sharing options...

250swb Posted February 22, 2020 Share #6 Posted February 22, 2020 I agree the original dial is nicer, and the the contacts are the same compared with my early MP, but I'd just be worried about the radial scratches. If they were simple wear and of no consequence they'd be longitudinal wear in line with the film path, these appear to have an arc, which makes me think perhaps somebody has tried to polish something out.

And the iso dial seems a lot better too, the MP one is a PITA to turn. 1 Quote Link to post Share on other sites More sharing options...

I thought my MPs had them but on checking my empty body they are absent, but I've seen many photos of pressure plates with these lines. I'm sure they will be present on my other MP and they are present on my M2's pressure plate.

I'm sure they will be present on my other MP and they are present on my M2's pressure plate. The undamaged texture from the honing stone used to make a perfectly flat surface isn't what I meant, but I was indeed unclear. When a pressure plate is polished to remove scratches it removes the black coating and the honing marks start to appear silver in a radial pattern, the honing pattern. Films going through the camera in my opinion don't shine up the honing pattern in the same way, it picks out random areas of wear joining the radial honing marks with longitudinal wear. I only suggested it has been polished because of what appears to be obvious damage or deep scratch to the MP pressure plate near the top left corner and some pitting to the bottom left corner (both in 2nd photo). Obviously you don't agree with me that it is damage so sorry for suggesting it, but good luck OP. Edited February 24, 2020 by 250swb Quote Link to post Share on other sites More sharing options...
a.noctilux Posted February 24, 2020 Share #11 Posted February 24, 2020 Gavbo, Out of topic, but who knows ... my suggestion, if one day you want to transform your MP to pseudo M-A (no LED to disturb your framing !) or if you use 100 ISO only film, the M4-P or M4-2 is as flat outside and "cool looking" as can be 🙃 Welcome, dear visitor!

Laidley Posted December 23, 2020 Share #14 Posted December 23, 2020 (edited) If anyone else is interested in doing this M6/MP door swap this isn't guaranteed to work from what I can tell. I have two m6 back doors and neither work on my MP. The potentiometer on the m6 rear doors are off by a full stop at ISO 100 and gradually grows in discrepancy as the ISO increases. I checked the contact resistance on both M6 doors and everything is in spec. So I'm not sure if there was a change to the light meter in the body of the MP at a certain serial number but my MP is 2921xx and the swap does not work. Also of note, after removing the pressure place on both the MP and M6 doors the potentiometer housing is completely different. I'm now wondering if the first batch of MP cameras that have the M6 style ISO dial have the same internals as the M6 or if its only the dial itself that is the same. I'm about to send the camera to NJ for a full CLA and will ask them what the deal is. Just be aware that your mileage may vary. *To add. I just tested the resistance of the pins on the MP film door and they are significantly different than the M6 doors.

Capuccino-Muffin Posted April 14, 2022 Share #15 Posted April 14, 2022 M6 doors will work only on M6 cameras. If it works on a MP, that’s because the MP in question is a M6 with a MP top plate, or in other words: very early MP production. Quote Link to post Share on other sites More sharing options...
romualdo Posted April 22, 2022 Share #16 Posted April 22, 2022 One question - not sure if this has been asked before - If your MP has the "old" style (M6) ASA dial, will that always be associated with an M6 door or can that dial be found on the later MP doors?

This question has come up again recently on this forum and it would be good to a get a definitive answer. Quote Link to post Share on other sites More sharing options...

This question has come up again recently on this forum and it would be good to a get a definitive answer. The EV range of the M6 (the one where you can't get the meter repaired) is EV0 to EV20, and it uses two triangles in the display. When the M6TTL (the one that can still be repaired) was introduced the EV went up to EV-2 to EV20 and the display uses two triangles and a dot between them. So it's not even the same metering circuit between the M6 and M6TTL. The early MP, according to my manual has and EV range of EV-2 to EV20, so the same as the TTL, plus the same display. This is the same as Leica's published data (2006) for the MP after they changed the dial from the M6 style of dial. So when the camera repairer says the meter for the M6 can't be repaired they literally mean the M6, not M6TTL or MP early dial or MP late dial. 3 Quote Link to post Share on other sites More sharing options...

PFM Posted June 7, 2022 Share #20 Posted June 7, 2022 Here's a thought going in a different direction. Can the M6 door be used on the M4-P? I'm not looking for any functionality except to have a better ISO reminder than that stupid write-on pad. PF Quote Link to post Share on other sites More sharing options...
