None of the Contax N lenses are focus-by-wire. There is direct mechanical linkage from the focusing ring to the focusing group lens elements and no power is required to do manual focusing.
Maybe we could use a little clarification first on what is meant by "by-wire". It means an electronic circuitry reads from a user-interface control (here, a focusing ring), performs some calculations and/or does some checking/limiting, and then sends electrical signals to drive motors and/or other actuators to control something (here, the focusing group lens elements). In a "by-wire" system there is no guaranteed direct linear relationship between output and input. A computer may decide your input is out of range and skip the output instead of obeying your command. A characteristic of every "by-wire" system is it requires an external power source to work. (Although the reverse is not true, e.g. power assisted steering and braking of a car are still not steering/braking-by-wire systems.)
A by-wire system may have some lag because it takes time to read the sensor, do calculations and sends the output. (Although microprocessors are so fast these days that the calculation part is negligible.) It is also limited by sensor resolution as well as the output resolution of the control motor. (Although even in a purely mechanical system, resolution is still limited by backlash of gearing.) A good implementation of focus-by-wire can exceed a poor implementation of mechanical focusing. (e.g. the focus-by-wire Canon EF 85/1.2L would be smoother than most AF lenses in MF mode.)
Thanks for the correction & for clearing that up!

I'm really hoping this is a M9 beater because by paring down to a reduced film only M outfit, it should be possible to finance it by selling some film M gear.
I wonder how many M users might do the same thing? if this camera is a riotous success (and I am not saying it necessarily will be) then it could really change the marketplace for M equipment.

The price of M mount lenses will probably continue to rise and film bodies may fall.
I should have taken TomA's advice and NEVER sold any M mount or even LTM glass.

I hope these lenses have proper mechanical linkages. They look like they do. I hate fly-by-wire. Don't tell anyone I said that, though.

This carefully timed leak has killed all the hype around Nex-7. Suddenly that attractive Nex-7 is no longer that attractive.

Some new details from www.photorumors.com (some more details there);
Viewfinder;
Similar hybrid viewfinder like in the x100. The X-Pro 1 will have two optical degrees of magnification: x0.37 for wider lenses and x0.60 for the other lenses. This function will be controlled by the menu and can be set manually for third party lenses.
Lenses;
XF 18mmF2 R
XF 35mmF1.4 R
XF 60mmF2.4 R Macro
Later this year Fuji will introduce more lenses, including a telephoto and probably a 23mm f/ 2.0.
Fuji will also launch their own M bayonet adapter for Leica lenses

With a Flange distance of 17,7 mm I hope some adapters may be build like the Nikon S mount.

It would be great if the purpose built Fuji adapter would be able to read the leica lens coding, change the OVF magnification and then project the correct frame-lines. Will the xpro-1 firmware be able to project frame-lines other than the 28/50/90 set?
Or is the adapter a dumb device, where all setting must be done manually via the menu?

Unlikely, that's covered by patents.
However, it would be cool if the adapter had a rangefinder roller and you'd get parallax-corrected framelines for whatever focal length you dial in, and distance information in the EXIF data.

Ahh..come on, anybody can read dots. In fact, we'll add a few so the user can put in the lens manufacturer. We'll call it the new expanded coding system for legacy lenses. This open standard will be used by adapter designers for the digital/legacy interface that cameras like the NEX and XPro-1 (no doubt others) will use.

if true, this is great news! Hopefully it means that Fuji will incorporate M-adapter-friendly features into the design.

Now if it could somehow in dreamland handle my Contax G lenses I'd be standing in the door of the first place selling them. Unfortunately, this doesn't even fall under the dream category.
Since apparently it will accept M lenses, you'll also be able to use G lenses if you convert them.

if this new kit is as good as the x100 is...image quailty wise...i just might sell everything and buy it.
and then live happily ever after!

I still remember the bashings about the M8 having a 1.3 crop factor 6 years ago. Makes me realy smile to see all the excitement about a new RF type camera with the sensorformat of the 8 years old R-D1

Well, Fuji is offering the right set of lenses for their sensor format ... That was not the case when the M8 came out. Especially since people already owned M-mount lenses with an angle-of-view matched to their preferences in the 135 format. Also, sensors got a lot better since then, so that the difference between smaller sensors and larger ones is not as noticable as it was 5 years ago.
I do not have a digital camera right now, but this Fuji looks really interesting ... It is the first digital system that looks like it matches my preference for camera format and shooting style while being affordable by me.

Metabones sells a Contax G to Sony NEX so why not Fuji in due course?
