Some color correction would be nice.
The image from these cameras has a really annoying green-ish tint, even in soft, warm, lighting conditions.
Playing with the Brightness/Contrast/Saturation cannot solve the problem, it's a matter of color balance/hue adjustment.
(It doesn't have to be a user-adjustable feature either, just a one-time setting adjustment in the firmware. I doubt that anyone likes the current green, underwater-looking image.)
The DCS-920, for example, produced a much better balanced image.
