I can't afford a new camera like this, but I went along to the "Touch and Try" session (with Madame's permission . . .) at CameraWorld in Stevenage this morning.
I had the Fuji rep to myself and he was very instructive; although we discussed the X-Pro3 we also talked a lot about other matters Fuji, for instance how to focus when using the extension tubes (use Manual and visually assess the depth of field, or use peaking),
The X-Pro3 is an interesting design and I would buy one, but I might consider its predecessor instead.
