A while back now I got a Canon Powershot A720 to use as a portable compact camera. It's rubbish. It's really grainy, takes ages to focus and eats up batteries like there's no tomorrow. The "optical viewfinder" is a total joke and is about as useful as the one on my Holga for accurately reflecting what's in shot.
It does however lend itself to being deliberately grainy for the purposes of being a little bit arty. Here's Kitty in a rare moment of cooperation where she did a classic cat pose. I ran this through Lightroom and added a slight touch of blue to the shadows and quite liked the result.
