I am at the point where I really think to own too many lenses for the M.
And I understand that for good photography I wouldnt need more than 4 or 5.
But everytime when I try to decide a lens I find some reasons why I dont want to sell it.
For example Noctilux 0.95. In one way I find it too heavy, and use Summicron much more often, but then I tell myself it is a unique lens.
Or the Zeiss 85/2.0 same here, pretty big and heavy, and I allways use the 75/2.0 instead. But then I say the 85/2.0 draws so nice and who knows if I would find such a nice sample again in the future if I wanted one.
Overall however I often wonder if these minor differences in "character" of certain lenses are not really overrated. If it would be more important to just focus on the subject/photography thing and less on the gear.
But how can one get rid of this "gear" lust?
Same true for the MM...can I see a difference? Yes. Did I ever feel B&W from the M9 are lacking something: No. Do I want to sell the MM? No... but why?
