Hee hee... actually my main point was to knock over the silly straw man that any single piece of equipment is "best," though one of these days I'm going to just have to make a wee web page on my site just to educate the world on the correct way to use the G2 autofocus — a method that's quiet and quicker than anything I've managed with a Leica (I've had IIIc and M5 models in years gone by).
Current 45mm Zeiss on ebay: ~$150
Current 50mm Summicron: ~$650
Current 50mm Summilux: ~$1300
So for someone like me shooting HP5, the difference is about 300 rolls of film and processing -- for the Summilux almost 700 rolls or 25,000+ exposures. And that's not even bothering with the cost difference between additional lenses or between a G2 body and a beat-up M4
One wonders if that reasoning played a part in the minds of switchers to Contax like Luc Delahaye, Robert Frank, or William Eggleston...
