SilkyPix supports the GFX. If you are not used to it, it may seem a little weird, but it is actually quite good, and essential if you also shoot pixel shift files with a Pentax K1. Adobe will add support later this week.
The 120mm macro is excellent. No CA to speak of, and while it is "only" F4, it is great for studio product / food work etc as well as portraits - and it is has optical image stabilisation, which I don't think the upcoming 110mm will have.
Best of all, it looks and feels like a regular DSLR. Joy of joys, you can change the aperture on the lens. Call me old fashioned, but that make a difference to me.
Collect the 32- 64mm this Friday. Very impressed so far and happy to again be a Fuji shooter.
