Olympus ZD 25 f2.8
I really like this small camera (E420/E620). It's not really all that much bigger than the m4/3 cameras. I usually use the PL 14-150 or the ZD 25 f2.8 pancake lens on an Olympus E420/E620. Images produced with those two lenses are very good.
The following gallery is an example of what is possible with the ZD25 f2.8 lens.
