Hi folks, I've got a G5 with the Sigma 19mm, the Sigma 30mm, the 14-42 kit lens, the 45-150 zoom, and a couple of Minolta MD mount lenses (50mm 1.4 and a Vivitar 105mm macro). As you may have guessed by now, I have a budget at the lower end when it comes to lens purchases. Anyway, I'm thinking about my next purchase, and I'd like a pancake with a wider angle. Is there any reason I'd consider the Oly 17mm 2.8? It is in my price range, but seems like other than size, it really offers no advantage over the Sigma. Is that correct? However, the Panasonic 14mm sounds pretty nice, especially considering its price. In real life, do people find that the 14mm vs a 19mm makes a real difference? Is it worth carrying both around? Or should I put my pennies in the piggy bank until I can afford something wider (and much more expensive)? Other possibilities?
