In particular the: Summicron-M 50f2 (11826) measured 46mm spec 43.5mm Summilux-M 75f1.4 (11810) measured 82.5mm spec 80.0mm Summicron-M ASPH 90f2 (11884) measured 83.5mm spec 78mm These are fairly significant differences, can anyone confirm the length of their 75 and 90 for me? Also has anybody a clue if the yet-to-be released M ASPH 28f2 will have a new dedicated hood or will use one of the existing models?
