I have been shooting landscape on H2 with P45 for many years and wanting to find a smaller unit which I can carry around. I am about to take the plunge with the Leica M9, though it will be my first time using a rangefinder. my question is: if I am only going to purchase one lens for the M9, which one would you recommend? I am am thinking either Wide Angle Tri-Elmar-M 16-18-21mm f/4 Aspherical or 50mm f/1.4 Summilux M Aspherical.
I hope to hear from you all.
I think you should keep it simple and keep it Leica. That way you avoid any 'characteristics' of other manufacturers lenses that are best learned about gradually and learned well before deciding to buy them.
For the focal length the WATE is going to be very limited for landscape work, everything will look like a pea on a plate, and even the tallest mountain will look like an anthill. So I'd recommend either the 28mm Summicron, or 35mm Summicron, and if forced would say the 35mm. They are both do-it-all lenses that are good for most things except portraits. But whatever you start with consider the spread you could end up with. The logical ones to go with the 35mm are a 21mm and a 75mm, that gives a great universal spread. The logical spread with the 28mm would be a 50mm, and a 90mm, another great universal spread. Avoid getting 'the next lens along' like buying a 28 and then a 35 etc, these can be added much later.
As soon as you get used to what a good Leica lens does (sharpness, contrast, bokeh, colour etc) its possible to judge other manufacturers offerings, some of which are terrific, some not so terrific.
