There are people who play and people who watch (people who live life and people who wait). I am clearly a watcher but I am working on my playful side.
Today I went to a Phase One dealer, the representative demonstrated a couple of backs and the camera, thank you. Some findings (there is nothing better than handling the equipment yourself, not even following the brand for years and downloading sample photographs):
1) The photographs are even sharpen than I thought.
2) Sharpness fades away sooner than I thought.
3) There is _no_ noise at ISO 50 (native) and ISO 100.
4) The Phase One is very stable, releasing the shutter is relatively silent and does not cause vibration in the machine that I noticed.
5) The center of gravity of the Phase One is a bit far back (with 80 mm and 55 mm lenses), together with the angular shape of the body handholding will need a bit of getting used to.
6) The thumbwheel is in the wrong spot (for my small hand), to operate it I have to let go of the grip almost entirely.
The prices are pretty high, so the verdict is still out.
