Ok so this questions been bugging me for awhile and I'd probably sound like a noob asking it but why do lenses with such small f stop #'s fetch THAT much more in price? I understand the concept of letting in more light thus a premium.. I get that but mechanically the lenses iris is just being made so it folds in more this making the amount of light coming in greater.
I never really understood why not just make the iris of the lens open up as much as it can, maybe make a little opening in the body of the lens so it sits completely outside the range of the glass and be done with it.
Granted I know its Leica and their craps expensive but still why the large premiums for just simply opening a lenses iris more.
First, this a Leica product. Expect to pay more.
Second, this is a Leica product. Their quality is very well known and highly regarded. (Ignoring the issues with the M8 for the moment).
Third, this lens is tiny, think of the amount of engineering that has gone into this compared to say the Canon 50mm at F1 (though rare).
Fourth, the optics are going to be the best out there.
Fifth, they are hand made in Germany, not shipped out and massed produced in Asia, their market is smaller and thus economy of scale comes into play.
Sixth, I think the lens is four times faster than the human eye and that has to come into play (I'm guessing here) when it comes to durability, the mechanics are sophisticated.
Seventh, nobody else is doing such a lens, even less so for the Rangefinder.
You know why Rangefinders probably don't have IS? One reason is because it allows some photographers to hand hold at 1/8th of a second, there is no mirror plate to bounce the light in the camera 4 times till it hits the film/sensor.
Compare that to an SLR setup where some people can hand hold at 30th of a second with a f1.2 lens.
The Eighth and final reason is the red Leica badge costs a premium to make.
