ayewing Posted October 18, 2015 Share #1701 Posted October 18, 2015 Advertisement (gone after registration) Being a topic starter of that thread I feel the deepest sad that Leica is not presenting a new M but trying to kill the M philosophy introducing the substitutes of great M system. But surely the new SL (or whatever it is called) is not intended as a replacement for the M line of cameras. It is a new mirorless ILC with autofocus and zoom lenses which will appeal to a different user group from the diehard rangefinder afficiandos. That it may be able to use M, S and R lenses is an added bonus that will make it more appealing to longstanding Leica users who already own Leica lenses. Probably a new M will appear next year as mjh has hinted. Link to post Share on other sites More sharing options...

Why should Leica hobble themselves by sticking to one system? There is no objection to diversifying. Link to post Share on other sites More sharing options...
mjh Posted October 18, 2015 Share #1704 Posted October 18, 2015 ........ does anyone know whether T lenses will give 35mm coverage ? ........ T lenses are APS-C lenses. I think I’ve said that a couple of times now. ........ I always thought the T mount was unusually large for the size of sensor in the actual camera ........ Not that unusual as mounts of mirrorless systems are relative large, as a rule. But even a larger sensor behind that mount would not change the properties of the lens.

Edward, Would you have said this of the R system? I have no doubt that a new M will come eventually. Link to post Share on other sites More sharing options...

Michael, Is the T-mount wide enough for a 24x36 sensor? I know Sony's E-Mount "works", but it seems to be too narrow or too far from an ideal size, maybe an improvised solution based on the former Nex system (designed for APS-C sensors). Lets imagine Leica is free from any legacy mount, would they adopt a mount like the T for a 24x36mm mirrorless system or something wider? Link to post Share on other sites More sharing options...
luigi bertolotti Posted October 18, 2015 Share #1707 Posted October 18, 2015 Advertisement (gone after registration) Michael, Is the T-mount wide enough for a 24x36 sensor? ....Sorry to act as Michael (not pretending to have his knowledge....) but seem to remember that the issue was discussed here...and the answer seems to be "yes", based on technical considerations on dimensions involved.... even if of course it's just Leica who can confirm this... iirc they never made an official statement on the matter.

Lets imagine Leica is free from any legacy mount, would they adopt a mount like the T for a 24x36mm mirrorless system or something wider? Technically the T mount is large enough for a 36 x 24 mm sensor – it would be a much better fit than the E mount, for example. From a lens design perspective one would prefer an even larger mount, but camera design is a different matter. A 35 mm camera with the height (though not the depth) of a medium-format camera may not be all that attractive. So the question is how large the mount must be to allow for the kind of lenses you want to design on the one hand and for a body of 35mm-like dimensions on the other.

Mistral75 Posted October 18, 2015 Share #1709 Posted October 18, 2015 How different can/must a camera be to require registering a new Typ designation? s-a Only if there is an innovation that needs a patent. There's no particular reason to patent the new version of a camera just because it's new. Remember the M Monochrom (Typ 230) that got registered with Korea Radio Research Laboratory in May 2014? That was just the silver version of the original M Monochrom. These registrations with radio certification authorities have nothing to do with patents and are linked to the radio-emissions of the device (Wi-fi, NFC and more). The silver version of the M Monochrom (Typ 230) had to be registered independently from the black one because the metal the body is made of is different, hence the 'radio behaviour' too.

The inner diameter of Leica T mount is 51mm, much bigger than the diagonal of 24x36 format (circa 43mm) and bigger than the diameter of Sony E (46.10mm) and Leica M (43.60mm) inner diameters. So yes, the Leica T mount is wide enough for a 24x36 sensor. It's even wider than any SLR mount but the Canon EF (54mm) and Contax N (51.6mm) mounts.

So yes, the Leica T mount is wide enough for a 24x36 sensor. Yeah, like I said. The reason why people are wondering is that the design rules have changed since the previous century when the established SLR systems were designed. These days, mirrorless systems have mounts that are much wider than the image circle – not just by a couple of millimetres but by 50% and more. But then these are systems designed for APS-C or FourThirds. So the question arises what the ideal dimensions for a mirrorless 35 mm mount would be. From a lens design perspective that ideal mount would be larger even than the Canon EF mount. Having said that, such a large mount may not really be practical for the reasons given above.

semi-ambivalent Posted October 18, 2015 Share #1715 Posted October 18, 2015 Remember the M Monochrom (Typ 230) that got registered with Korea Radio Research Laboratory in May 2014? That was just the silver version of the original M Monochrom. OK. I asked because I wondered if it was possible not to have to register if the (new) product was simply a 're-arrangement' of already extant sub-assemblies. Like an 'old' electronic RF in the M. It's really too much subterfuge, all things considered, but Leica seems to have really kept the lid on things this time around. As if it is really big this time (as befits their anniversary). Oh well, it's all moot in a couple days... Thanks, s-a Link to post Share on other sites More sharing options...
gpwhite Posted October 18, 2015 Share #1716 Posted October 18, 2015 49mm for Leica R mount. For Leica S I don't know. At its most constrained point (i.e., the inboard locking lips), my S typ 006 sports a 63mm mount ID. Link to post Share on other sites More sharing options...

John Black Posted October 18, 2015 Share #1718 Posted October 18, 2015 The Monochrom didn't have any radio frequency in either colour - no WiFi, NFC or anything else. It still emits RF.

Mistral75 Posted October 18, 2015 Share #1719 Posted October 18, 2015 the Leica M Monochrom Typ 230 is (...) the stainless steel version as part of the limited Leica M Edition 100. Because of the different material it needed a new certificate from the Korean telecommunication agency. http://www.l-camera-forum.com/leica-news/2014/05/leica-m-monochrom-type-230-leica-m-monochrom-silver-chrome/ Link to post Share on other sites More sharing options...

Doesn't every electronic product have that sticker? Does that mean they are all registered in Korea? I don't know the answer to any of this - I'm just curious.
