I don't know if it was the camera, or simply some good luck, but a two hour walk yielded four portfolio-grade images. Remarkable.
How is the camera? First impressions are that image quality is spectacular, including the lens and the sensor. The user interface at first appears to be ideal, with traditional manual controls for exposure. But, once you have to use the rear control wheel and menus the cursing starts.
My review will appear here in about two weeks, after my drive back to Toronto from Mexico. I plan on shooting extensively with the X100 along the way. Some interface issues notwithstanding, the X100 looks like a winner."
