Canon Powershot S95.
Full Manual Controls, F2.0, awesome photos, and the smallest of all. I owned it, sold it, went to the market and bought it again because there isn't any other which comes close.
Price : 399USD.
Olympus XZ-1.
Though better on the paper with F1.8, the final image quality isn't as good as the S95. Actually this is the camera which I considered after selling my S95. It wasn't available here in Kuwait, so e-mailed Olympus to get it available. Its bigger than S95, considerably. On the positive side, you can shoot faster with xz-1, and with longer exposures than in S95.
Price : 499 USD.
