Originally posted by Winder Fuji, like Canon, Nikon, & Panasonic have opted for optical image stabilization. Fuji has plenty of its own money, vision, & continuity. I don't think Fuji will produce a FF sensor. All the indications are that they will produce a medium format mirrorless if anything. Fuji already makes all the medium format lenses for Hasselblad and the large HD broadcast lenses for Sony. Fuji has a long history of medium format range finder cameras.
My thoughts as well, the X mount doesn't fit FF sensor, so if Fuji were to make a FF camera, they need a new mount and new line of lenses, however, for medium format, they have experience, and so does Pentax thus Fuji might gain some benefits if they work together with Ricoh to make a Digital medium format camera.
Originally posted by Winder IF anything Ricoh needs someone with Fuji's lens production capabilities. The Fujinon glass is excellent and Fuji has demonstrated that they have significant capacity to develop and produce a significant number of high quality lenses very quickly. This is something that Ricoh needs for K-mount. I could see Ricoh turning to Fuji for glass and that would not be a bad thing for K-mount users.
Agreed, Ricoh does need good optical companies that has the production capabilities and capabilities to design quality lenses. I would pretty happy if Ricoh to work with Fuji to design future D-FA* or D-FA primes that's on the road map. Also Fuji's excellent JEPG engine might also add a bonus to Ricoh to adopt as well.
Overall, I would be happy to see Ricoh/Pentax work together with Fuji, both companies understands photography and photographers and produced lots of intriguing photographic tools.
