If I am serious about 21 outing Nokton it is, if it is low light Nokton it is, but if I am doing a sort of one lens carry, my one lens plus strategy of a 50 mm apo summicron with M11 I might well put the 21 and 28 color skippers in my pocket as a just in case, small enough I forget they are there, and if the light is generous I have wide angle.
