OK this is another one of my dumb questions, but I have dropped the noobie bit - I have been asking these for a while now so I no longer feel that I qualify as a noobie.
A 1933 Leitz brochure "Directions Leica Camera Model II" says that the Elmar 105mm (10.5cm) f/6.3 lens is a "relatively small and light distance lens" weighing 7 ounces, and "is particularly favoured by mountaineers". It goes on to say "Its lesser aperture is in most cases perfectly sufficient, as when photographing distant views one mostly has to stop down to 6.3 in any case, in order to overcome unsharpness which may arise due to distance haze."
We know that the 105mm "Berg" (mountain) Elmar was made by taking a lens already computed for a medium format camera and putting it in a Leica mount, so any suggestion that the lens had been designed from the outset to be a lightweight lens of deliberately modest maximum aperture goes out of the window. And I don't think that you can remove the effects of distance haze by stopping down. To me, the description sounds like typical of what comes out of a marketing department when they are presented with something that the engineering department has already made and they have to dream up some flim-flam to make it sell.
If I were going mountaineering I would personally be more inclined to take a wide angle lens rather than a 105mm long lens.
So my question: If you were going mountain climbing, would YOU pack a 105mm lens?
