Initial impressions are that I don't like the control setup nearly as much, and there are lots of little things about the GR that I never knew I valued so much. (Like the level indicator on the LCD—maybe the Fuji has one? I can't find it, if so.)
I'm planning to take it to Santa Barbara this weekend, so hopefully I'll get some good shooting time in with it and be able to develop a more in-depth opinion.
EDIT: Found the level but it's not as good as Ricoh's.
I was about to pull the trigger on GR when the X70 was revealed. Look forward to your thoughts.
I like the inclusion of a tilt/touch screen, the Fuji JPEG engine and slightly better high ISO performance.
Downsides are that it seems slightly fatter/less pocketable, heavier, no ND filter.
Would be interested to hear about the lens performance, flare resistance and rendering compared to GR
I never got either of the conversion lenses for the x100 and I doubt I would get the one for my X70. For me at least it ruins the compactness of the camera and having to remember to activate the lens in the menu is a pain. I wish it were more like the Sony UWA for the 28 with a magnet to trigger the adapter.
On the x100T you can program it to a function button. I have it on the trashcan button during shooting mode (because it's otherwise unused) so can activate them with a single button press. Easy.
