Well, EX-1 is another camera that you don't have to pay alot to get among the best in PnS. In a nutshell from LuminousLandscape review ...
Conclusion
There's a lot to like about the Samsung EX-1. Build quality is exemplary a notch above what one usually finds in this price point. The lens is as good as it gets for a camera in the price range, and indeed better than many. Ergonomics and other handling issues are par for the course, and again, better than most.
Image quality is on a par with other cameras of this type, and the EX-1 in no way suffers by comparison with competing models from Canon or Panasonic. It's only when it comes to its primitive video capability that the EX-1 owner is let down. If video isn't important to you then not to sweat, if it is you'll likely want to look elsewhere.
Fast lens, great lens, solid build, decent IQ, smooth handling what more can one want from a pocket camera in this price range. Highly recommended.
