Mirrorless Rumors have more photos and a (rumoured) specification list which you can see and read here
- bigger (x77 magnification) and better (high performance) EVF
- APS-C X-Trans sensor II (16MP)

- dual SD-Card slot
- 8fps with AF tracking
- weather sealed body
- tilt screen
- SLR-type (Fujica) design
- name: X-T1
- ISO up to 51200
The page also suggests that the price will be somewhere between that of the X-E and X-PRO lines. Does that mean that this isn't the X-Pro2?
The new camera certainly looks exciting but if size is an issue then although the body may be compact one also has to look at the size of the lenses one is likely to buy. Comparing the FUJINON XF35mmF1.4 R and the m4/3rds LEICA DG SUMMILUX 25mm / F1.4 ASPH (similar FoV) there's not a lot in it but the m4/3rds system does have a number of smaller, albeit dimmer, options. The reviews of the X-T1, when they finally arrive, will make interesting reading but I somehow doubt that the latest and greatest from Olympus, Panasonic or Sony will crumble before its feet but I'd guess it will be comfortable in such company.
P.S. I still find it extraordinary that one can dismiss Canon and Nikon from such discussions but until and if they decide to compete seriously in the CSC market they are hardly worth mentioning, despite the fact I just did!
