After looking at photos I really think a Rokkor-M (Summicron-C) 40/2 would suit my taste. But I need the speed (largely to use in tandem with my 75/2), so the Little Nokton it is. I see it just as a "place holder" until such time as I can get a Lux Asph.
I think the little Nokton 35/1.4 SC version (you sure move fast in the classifieds 😉) will keep you quite happy until such times you can spring for the Lux Asph, Jon. I'm looking forward to hear your thoughts about the lens, as I suspect you'll be pleasantly surprised with its performance, even on the M8.
