This year Fuji will release this superfast 200mm f/2.0 XF lens. Fujirumors just got a few tidbits about it:
Fujifilm had to re-design their current teleconverters, because they are only designed to work down to f2.8. Hence, for the start, Fujifilm will sell the XF200mmF2 WR also bundled with the new 1.4x Teleconvert (but not the 2.0x TC) for about $6,000.
The source also told us that the Fujinon XF200mmF2 OIS WR will introduce a brand new anti-reflection coating to reduce flare.
The lens will also be White and not Black (as displayed on the CP+ show).
