This update looks great, Fuji has earned it's reputation as an innovative company that does firmware updates instead of an endless series of minimally new camera bodies. We'll have to see if everything really works as advertised but in the past they've usually worked right out of the box.
Everyone has their own wish list depending on the type of photography they do. I'm not complaining but would like to see more flexible bracketing; for example to allow the ETTR settings in the recent article on LULA on 10/29 by Bob diNatale. It would be nice to be able to push the shutter once and get my three exposures. More megapixels would be nice too but that's not firmware...
I started with 35mm, went to 4x5 via 6x6 and 6x7, and have now worked my way down to APS-C. It seems to be a pretty useful format, the image quality is easily sufficient for the sizes at which I print, AND the lenses are small as well. Perhaps optical design will improve but the problem with full frame is that regardless of how small the camera, e.g. the Sony A7x cameras, lovely machines, but fast full frame lenses will still be quite a bit larger to cover the frame.
Viva Fuji.
