I tested the viral Sigma BF camera, and its radical redesign has me hooked

A major reinvention of the digital camera for simplicity and elegance gives prosumers lots of advanced features.

All the functions of digital photography are still there to be experimented with and exploited -- shutter speed, lens aperture, or "f-stop," and "ISO," the level of light that can be recovered from a scene -- but they are under your command in a radically simplified user interface. Rarely will fake bokeh give you a really complex, thrilling effect where both foreground and background elements are selectively blurred, leading to a more sophisticated image, such as this cypress I snapped in New York's Central Park: There's also an option called "look effect," where you can dial up or down how vivid or how flat a given color filter is, which is a nice, obvious way to understand making your pictures or videos more striking or more sedate.
