It's £600 with finder, that's very serious money for the performance on offer. And I'm still not convinced by Foveon sensors, every time I see highish ISO shots they look poor compared to the opposition. A compromise too many I think. The forthcoming Olympus E420 with 25/2.8 pancake prime looks like a much more interesting option at £450. It's a bit bigger because it's a DSLR, but still easily pocketable.
All academic for me, as I'm not looking to buy a digital camera of any sort, but I think the DP1 looks like it needs more work.
