I've been carrying around the C330 and trying it in a variety of settings. The hand-grip is a big help in keeping my fingers from inadvertently changing the settings. The Porroflex finder allows simultaneously achieving sharp focus and composing the image without flipping back and forth between the waist-level finder and the flip up focusing magnifier.
Some subjects, like the wine glasses, because of their placement simply would not be within reach without the eye-level finder.
The one thing I haven't tackled with the camera that I need to get to is portraits. I'll look for an opportunity to try that soon.
