Well, if the picture on the right is legit, than there is definitely something to expect. It would be an awe full lot of contacts if it was only for 6-bit coding. I think they somehow really managed to put a potentiometer or something into that adapter that reads out the distance setting format he lens. If they do that, i will probably be the happiest person on earth.

When does the fuji adapter for Contax G lenses come out??

sorry.... complete brain fade..... I meant OVF

Yeah, got it, Robert, but can you mount Contax G lenses with it? That's what we're trying to figure out here.

What am I missing here? He showed you a G to X adapter. What did you mean then? I'm just curious, not being an ass.

I'm kidding! As was j.scooter. People keep asking the same question without realizing it has already been answered earlier in the thread.
Ah, I see...

A friend of mine mentioned some rumors floating around fuji USA. He's heard the adaptor will launch with a firmware update that places a digital overlay on the ovf that includes a rangefinder patch.
I don't at all get how that would work from a tech standpoint. Not sure I buy it.

I have no idea if it will work, but if it does... my goodness, I'll make a mess in my pants.

It seems if that were true, Fuji would have at the very least leaked it by now if not outright advertised the fact.
That would be a major feature and sales tool.

Lets apart if this is true rumor or not. But from a technical point of view, it is very possible to simulate what you mention.
Provided you gauge the focus information you get from every LTM/M lens with RF coupling cam. This can be done mechanically (the classic way) or with a non-contact measuring device in the XF/M adapter. The remaining engineering work is "only" software (combining this lens information with the AF metering system and displaying a useful graph into the OVF).
Not impossible, but if they really would...
Oh my dreams!This would bring Fuji to lead the M capable digital body crowd.
Or did this information leak from the M10 environment?

Maybe... on the other hand Fuji can slowly ramp up production to meet the anticipated demand; go through several firmware improvements, and sell quite a few XF lenses.
Leaking it early puts pressure on everyone and raises expectations. A suprise like we're speculating about could have a significant impact. Maybe Fuji feels they better really get it right as they will only have one chance with M lens owners. After all there are lots of different cam mechanisms and the cam can be out of adjustment. I can just imagine the outrage from some M lens users whoose out of spec cam mechanism causes problems. The firmware would have to work well with many focal lengths. If Fuji implements in-camera corrections for wide angle lenses, which lenses do they support and how many do you support before you release the product?
Developing a useful smart M adapter seems practical and very complicated at the same time.

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.

What "CAM" are you talking about?
Griffin

Well, there would have to be a cam follower inside the adapter in order to read the lens focussing position. I meant that cam, sorry.

Man... Fuji could demand some serious $$$$ for an adapter so capable. I "shutter" at the thought of what I might spend for one.

There is nothing to stop projecting a real-time, even magnified live view in a small centered box while the OVF is in use. The OVF overlay can project some incredible daylight contrast, so there would be no reason to close the front VF blind.
What you are describing below would work with phase-detect AF but not the current hardware. With phase-detect, the camera could tell you what direction to turn the lens ring (just like using manual lenses on an AF D/SLR). CDAF requires the camera to go past the focused point and come back to it. Not so practical for manual lenses.

Isn't that what focus peaking (as in Sony and Ricoh versions) does with contrast detect for MF lenses?
