Leica+Fuji?

I wonder if Fuji's delay in releasing the adapter has anything to do with Leica's (rumored) upcoming mirrorless announcement? Maybe this technology is something the companies partnered on and will release simultaneously (or Leica first)?
 
Leica or Fuji - who will move first?

Seriously doubt this given Leica's long standing partnership with Panasonic. However, if I were Fuji, I would get my announcement in first to stave off the possibility that we all dump our XP1s on eBay to raise cash for the next big thing from Leica. I know I'm weak ..... I've done this before! 😱

Couldn't the rangefinder patch be a small image coming from the live view? The triangulation would be then between the lens/sensor and the OVF. Although not horizontally aligned, a triangle is still a triangle right? Then when you move the cam in and out, the image in the evf patch will move left and right (probably diagonally up and down?) according to probably a lens specific formula.

I can imagine mounting any given rangefinder lens and the camera will ask you to focus first to infinity and then to the minimum distance, whereby you enter into the camera what the minimum focus distance is on the lens. Thus the formula is created, probably in conjunction with the focal length of the lens.

I think what Dante suggests is something different.

Yes, it would be possible to have a projected 'rangefinder' patch moving across the VF frame, like a trangulated rangefinder, if you have a sensor which detects the cam position. It could even be adjustable, of course, using software, so you could calibrate it for different lenses. But the fact that, as you point out, the lens is on a different axis to the OVF might cause problems, you would never have the overlay patch exactly matching the main VF view.

A simpler method might be to have a focusing patch, projected in the middle of the display, which focus peaks over that area alone - would be good for focus, recompose, altho again you'd have a slight parallax between the optical display and the projected patch.

An adapter that does sense the cam position would open up a whole new world of possibilities... but I have to confess myself slightly dubious that Fuji would do this in practice, simply because they seem so uninterested in making manual focus possible with their own lenses!

You can "never" have the focusing overlay match the main view in Leica m either. The rangefinder works by comparing the different views from different viewpoints.
That said, some of my old lenses have quite a lot of lateral wobble, to which the lens adapter can only add to. They wouldn't work well enough with such a rangefinder.

I'm talking about the fact, as alluded to by Griffin earlier, that the lens is on a different axis to the VF window - it's below it. Traditional triangulation rangefinders always have the two windows on the same axis.
 
Well mathematically speaking two points are always on the same axis. For proper triangulation the patch would have to move diagonally.
 
And, in contrary to the image received from an optical patch, an image from the censor would be blurred and unfocused. That might be a little annoying, I think.

Ha, this has been discussed many times, in relation to the X100, but you're the first person to hit on the flaw which means triangulated rangefinding won't work.
 
The speculation is all very fun, and discussion is often very informative about the workings of these cameras, but I have learned to downplay any expectations I may have about upcoming cameras or accessories. In this way I am not disappointed when they turn out to have bugs like sticky aperture blades (X100), cracked sensors (M9), black dots (5D Mark II), white orbs (X10) and the raft of other annoyances that have and will continue to crop up. It also keeps me from buying something too early, before such bugs have been found by others.

If the Fuji M-adapter does indeed have electrical contacts, and has some way of reading the coding on a lens, it will at least have a way of identifying the lens and applying necessary corrections. As for assisted focusing, overlaid rangefinder patches etc, those are the kinds of thoughts that usually end badly. 😀

Not sure if this has been posted yet, but I was just looking on the Fuji site when I saw this banner:

X mount 35mm on the way? If I wasn't so bad with money, I'd be saving for it right now 😎

Has anybody heard of a date when Fuji is going to release this adapter?
