dennersten Posted February 19, 2013 Share #1 Â Posted February 19, 2013 Advertisement (gone after registration) If i am understanding this page correctly: Â Leica Camera AG - Photography - NEW ADAPTER MAKES R-LENSES USEABLE WITH NEW LEICA M Â I can use all the 2 cam and 3 cam lenses? Â What am i loosing with using a 2 cam? Or is it no differences? Link to post Share on other sites More sharing options...

giordano Posted February 20, 2013 Share #2 Â Posted February 20, 2013 The adapter has no electronic or mechanical connections so it makes no difference whether the lens has 1, 2, 3, 1 or zero cams. Link to post Share on other sites More sharing options...

Â I am sorry to say that Leica missed here. They should have built inside the adapter a mechanism to control the diaphragm, allow view wide open and close it before the picture. They designed in the past so many accessories looking like swiss knives, why not here for a very usefull feature ? Link to post Share on other sites More sharing options...

They designed in the past so many accessories looking like swiss knives, why not here for a very usefull feature ?  I agree it would have been good to allow R lenses to be focussed wide open and stopped down when the shot is taken. That would have been a real advantage over using M lenses which of course have no mechanism for stopping them down. As it is, using Live View on the M240 will take me back to using a Praktica L with manually stopped down lenses in 1971. All viewing, focussing and metering is done at working aperture. Such is progress.  Leica have missed a trick by not providing an interface in the enhanced grip to connect to the R adapter with a solenoid in it to stop down the lens. Metering would still have to be done stopped down which might have precluded using A mode because the camera would not know what the wide open aperture of the lens is.  However, with the amount of money Leica were willing to throw at their "R solution", about €100 it seems, it obviously wasn't possible. Perhaps they were also worried that R lenses would have worked better on the new M body than M lenses... Link to post Share on other sites More sharing options...
marknorton Posted February 21, 2013 Share #8  Posted February 21, 2013 This is nice but i don't think it will adjust depth of field  The Live View through the lens will of course show the depth of field achieved through the working aperture. Live View through a Noctilux is a revelation. Link to post Share on other sites More sharing options...
biglou Posted February 21, 2013 Share #9 Â Posted February 21, 2013 This is an accessory, so i hope they rethink it later and propose a new one, even third party could think about it if there is a market. Link to post Share on other sites More sharing options...
marknorton Posted February 21, 2013 Share #10 Â Posted February 21, 2013 Without access to the camera interfaces and firmware, the most a third part adapter could do would be to introduce a mechanical latch to stop down the lens before taking the shot. I can't see that the ideal of open aperture focussing and metering and camera-initiated stop down could be achieved without some interface between the lens and camera.

Leica could implement that easily but if the mechanical latch is all that is availiable it could be better than nothing Link to post Share on other sites More sharing options...
earleygallery Posted February 21, 2013 Share #13 Â Posted February 21, 2013 Yes, something like the old Visoflex, could use a double cable release to trigger the shutter AND stop down the lens. Â Hey, they could add a proper prism viewfinder while they're at it too, won't drain the battery like an EVF. Â Link to post Share on other sites More sharing options...

Â Agree - I've tried a few EVF's and personally hate them. I don't like looking into a small hole at a mini TV screen. That's why most of the digital compact/system cameras on the market don't appeal to me at all. Â An EVF may have it's uses in some circumstances, and that's how I think it will end up being used on the new M, not as an alternative to the rangefinder or an accessory optical finder.

luigi bertolotti Posted February 21, 2013 Share #16 Â Posted February 21, 2013 Does the adapter also work with the M9? Â Mechanically speaking, yes... but you have no way to check focus : good for strong Wideangles (15-19-even 21...) and you need of course also an external Viewfinder Link to post Share on other sites More sharing options...
algrove Posted February 22, 2013 Share #17  Posted February 22, 2013 This is nice but i don't think it will adjust depth of field  I believe LV does show you the depth of focus as selected by the aperture you are using. Link to post Share on other sites More sharing options...
marknorton Posted February 22, 2013 Share #18 Â Posted February 22, 2013 I believe LV does show you the depth of focus as selected by the aperture you are using. Â Well of course. The image in the EVF or LCD displays comes directly from the sensor and is similar (I hesitate to use the word identical) to what will appear in the image. How could it not show the depth of field? Â In this respect, the camera becomes just like a DSLR - you are looking through the lens. Link to post Share on other sites More sharing options...

How could it not show the depth of field? In this respect, the camera becomes just like a DSLR - you are looking through the lens.  Exactly. But with DSLR you have the first option to view the image with the lens wide open, and it is much easier to set the distance setting with a narrow depth of field. Maybe someone will object that it is possible in live view to magnifie a part of the image and that this way you may focus exactly, getting rid also of focus shift. This may be true but certainly slow. We will see. Link to post Share on other sites More sharing options...
