Current Leica cameras use Sony sensors and Panasonic technology. So, is Leica not worth it?

@@TastyPrism You need to understand the situation back then. Electronic , autoexposure cameras were taking over the camera market. Leica made nothing but mechanical cameras. Their only SLR was mechanical. They desperately needed an electronic, auto exposure SLR and had no tooling or expertise for autoexposure electronic cameras. Minolta was making what they needed, so they teamed up with Minolta for the R3 and later SLR's. They slightly altered the look of Minolta cameras and stuck their logo on them. But Minolta was no Leica, and their mass produced cameras had problems with the electronics that thus affected the Leica badged versions. It was the early days of electronic, autoexposure cameras and reliability was often an issue. The Leica CL was also a rebranded Minolta.

I had two R3.. The first one I striped the advance gear , the second an R3 MOT safari, it lasted 20 years , shot 100's of rolls.. It even went out to Burning Man 3 or 4 times.. Ended up selling it in 2010 along with all my film camaras..

But the truth is that there was a collaboration between Minolta and Leica. The XE and the R3 use common parts in some aspects. Most notably the CLS (Copal Leitz Shutter), which was developed by Leica and manufactured by Copal. The film advance and electronics were also similar. The main difference, and this is crucial, lies in the design of the mirror mechanism. The XE had a fixed mirror, the R3 a transparent mirror. The exposure metering system of the two cameras is completely different. The XE only offers integral metering, the R3 integral and spot metering. The metering cells of the XE are located in the upper part of the prism, those of the R3 under the transparent mirror. The mirror drive mechanism of the XE is simply a traditional hinge mechanism, while the R3 uses the scotch-yoke mechanism of the earlier Leicaflex SL cameras. Not to mention that the alloys used in the R3 are different from those used in the XE. I would not call this a rebranded camera.

It all costs money. Leicas vary hugely in price. Rangefinders from 500 to 15,000. Glass prices also vary hugely. It also depends how much glass you actually want or need.

In found it by searching with the russian caracters designation of the clock, here it is: drive.google.com/file/d/1IlbzwEjbi4a6js8eOgC3YxdT8rD5VPFS/view?usp=sharing

@@msylvain59 Awesome! Thank you so much! There is only one page. Does this mean only 9 pins are used?

@@user-mp9rd4hg8b ahh you found this great video and get help - also read my comment above , i found the fitting connector i count ten wires for full S1 switch function , pin 17 - 19 is the heating directly or over temperature bimetall switch on pin 19

@@NTTom2 Yes, I did. This reminds me of the Internet of the 90s, where people shared information. I'm still not sure I understand the schematic but I will try and figure it out. I did find a compatible connector for it. Thanks again.

Bonjour Msylvain, J'ai franchi le pas et j'ai retiré très soigneusement le tapis en caoutchouc noir. En dessous se trouvent deux films Mylar superposés avec des contacts et des pistes conductrices correspondantes. L'alcool s'est glissé entre ces films et ne s'est pas évaporé. J'ai très soigneusement soulevé un peu la feuille supérieure et utilisé un petit sèche-cheveux pour évaporer le reste de l'alcool. Maintenant, le clavier fonctionne à nouveau. Ce qui ne fonctionne pas encore de manière satisfaisante, c'est la troisième position sur l'écran. Cela scintille. Je dois voir s'il y a des problèmes avec le pilote d'anode responsable.

In deine Mutti, ok😂

or stellar navigation device, it is called a "periscopic sextant" model A28450-00-001, some ebay sellers sell it at 1500 US$, got mine for a lot less 😇

@@msylvain59 Yes, for aircraft. Probably a Boeing 747.

@@msylvain59 I was going to say submarine periscope , are you planning to make a video of disassembling it?

@@strangerares Yes, but I found a parts list book of ebay for it, I need to order it first. Some infos here : prc68.com/I/S5807.shtml

here is the technical manual, it should help drive.google.com/file/d/1-KdhBZBOllSwu8N4q6eS7mD_o_lmshC-/view?usp=sharing

@@msylvain59 Thank you very much , I was looking for this , I cannot thank you enough God bless you

I have a few Datamath, they still work too, while the build quality was not terribly impressive on those imo.

My guess is a transformer to make the high voltage for the display. The other Sanyo black part is strange too, maybe a thick film ceramic resistor or some hybrid module.

@@msylvain59 Thank you for your kind reply

Hey Mike, I love your videos
