but you're forgetting, sigma is the biggest third party lens maker in the world, who happens to make some cameras. Fuji does intend to sell their sensors but way down the line. I think thwy want to.see how well the pro x does. I think they'll be surprised as to how well it does

Bottom Line:  Are you saying Fuji will fail if they don't sell their sensor to others? Yes or no?

not sure what you mean ,the hybrid vf is either a pure optical vf with digital info overlay this  will be either a stepped  magnification  with 28 50 and 90 fovs
or perhaps a continuous zoom optical finder like the contax g used ......and when macro or fovs that are better served by an evf it is switched  and offers the same WYSIWYG as an LCD ....this is truly the best of both worlds .... tremendously versatile, useful for any situation ,and pleasing to a wider  audience of finder users than either pure ovdf or evf would be

i love the x 100 finder.... its great , hopefull the very good evf in it  will further improve to the level of the nex 7

Sigma reverse engineers their lenses.

+1

fuji has the chance to become a sensor supplier  as well as a camera and lens maker ....micro 4 3 and apsc is a great market  ....sony makes money there panasonic makes money there .... if fuji makes a great new product  then they should sell it  and reap the rewards

id hate to see this sensor technology be sequestered by one company .....and olympus  offers no threat  its a different sensor size   and somewhat different market

Kodak used to make Four Thirds sensors for Olympus 

+1!

But unfortunately the X-pro1's optical finder has only two steps of magnification. So it will have to resort to masking frames for some of the focal lengths.
