The Lumix 12-35 is a top quality optic that delivers excellent image quality even wide open. Sharpness and micro-contrast are excellent giving shots a certain clarity and depth that only the best lenses deliver. It's significantly better than any of the kit zooms - and so it should be at the price. I find it excellent for general purpose use such as for events, landscapes, people and walk-around. Unless you're into specialised requirements such as dramatic perspectives from very wide-angle lenses or long lenses for sports or nature, then the 12-35 might be the only lens you need. In summary, if you're after a very high quality standard zoom then the 12-35 will fit the bill perfectly - but be prepared to dig deep into your pockets!
