I am set with my D3 and 4 Nikkor zooms but I am considering what direction to go with fast primes. No hurry just something to think about. ISO 25K and f1.4 could do some amazing things with dawn and dusk images. So its it Zeiss and manual focus or the Nikkor 1.4 primes. I am thinking 28,50,85.. Looking for POV s . I could ,of course, just wait for the R10 but..then I wouldn t have anything aquire?
