First off, you can most likely find a good condition M6 classic for $800-$900 now. Considering that is not much more than other fine cameras like a Nikon FM3, F100, Canon eosV, etc, it is really not that bad. Think about this for a moment:
If the M6 is $200-$400 more than another rangefinder, how much do you spend on other things in life? Cable? Internet? Fast food? It all adds up.
Now, I have been shooting since age 9, that is 30 years of shooting. For many year, I thought fact that Leica optics were 5-10 times the price of similar focal lengths was insane, insulting even. Surely, the lenses can't be *that* much better, I thought.
Well, three years ago, I decided that it was time to take away attention from shooting paid gigs and do a personal project. Many on here will tell you it is about Kodachrome.
So I had been shooting on a Hasselblad Xpan and some manual Nikon gear. The results were pretty good, especially from the pano.
Then I decided, what the heck, it is time to see what all the Leica hype is all about. So I picked up a mint M6 classic and a 35 2.0 Summicron for $1,700. I shot with it for a whole week, ran the film and was shocked.
Aside from seeing a much more rich image, I had a distinct feeling that I was an idiot for having not done this sooner.
So now I still own the M6, but I sold the 35 and replaced it with two of the very best lenses made for any format, the 28mm 2.0 aspheric Summicron and the 50mm 1.4 aspheric Summilux. Let's just say I am selling some Nikon gear now.
I own 9 cameras and dozens of lenses, the only one I really want to shoot now is the Leica. If you are a committed craftsman, obsessed about image quality and total sharpness, the new Leica aspheric M lenses simply leave everything else in the dust.
A formula one race car is about 10 times the price of a car that will go 75% it's top speed. So you pay 10 times more for a model that only gives you a gain of 25%.
To a race car driver, that extra 25% makes his career. It's not everything to every one, it is everything to some though...
