Leica M (240) -framelines single or pairs?

Hi there,

quick question, when you mount a M lens, will the new viewfinder framelines lid by LED light displayed single (i.e. you mount a 50mm lens you will only have the 50mm frameline dsplayed), or tradionally as pairs (i.e. in the above sample the 50mm and 75mm framelines will be displayed like pn previous analog Ms, M9, M9P, MM?

Thanks!

Thanks, given the original mechanical construction that make sense, I was somehow hoping that they would have updated/ changed it for more clarity in the viewfinder.

The only thing which has changed is that the light which used to come in through the window and its diffuser and then reflected off the curved mirror through the slits in the viewfinder masks now comes from (presumably) an array of bi-colour LEDs, white and red. It's much better than I expected, the advantage being the frames are clearly visible in low light with brightness being controlled by the same sensor used to control the brightness of the exposure meter LEDs which appear to be the same as the M8 and M9, M7 too come to think of it.

Good question. Given the existence of lens detection, and the redesign of the frame line section of the range finder, one would think that the new camera could have have brought up one frame at a time.

Why? There is no re-design. The frame lines are just the same as in previous models, just that they are illuminted by an LED bulb instead of a window on the front of the camera.

 

The lens detection does not alter the framelines either, it is a mechanical function of the lens bayonet.

It's mechanical and one at a time would require 6 frameline masks. I don't think there ie enough room in there for that.

Visible in low light is great news.

I think it is not convenient to bring one frame at a time because of the fact that every 2 focal lenses always bring two frames together since these lenses share the same base plate , such as the 50mm and the 75mm, or the 28mm and the 90mm. Therefore we would have to Change the base plates of the lenses.

Please correct me if I am wrong (and excuse my English).

I think you are right, I forgot about that, good catch!

I think part of the confusion may be that Thorsten's rolling review from last Sept. states,

 

"No manual selection of frame lines and you only see the actual frame lines for the actual lens, not two pairs."

 

Perhaps the prototype he saw was like this, or it could just be an error.

There is a mechanical linkage between the frame lug on the lens mount (which has only three possible positions) and the frames that we see through the viewfinder. The 6-bit codes are detected electronically, passed through the firmware which looks to see if there is a name, a vignetting and other corrections profile, and passes that information to the chips on which the image will be processed after you press the shutter and to the display of information in the viewfinder. The connections between the mechanical and the electronic parts of the system are very few (and that is a good thing). The camera electronics knows about the shutter speed and the frame lug position (2 bits). It used to be that you could override the frame lug information by pushing (not pulling) the frame lever, but that is now gone.
