[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]I shoot with a Nikon D3. FX Full Frame like the M9. The D3 has a native (and clean) ISO6400 with H1 and H2 giving "ISO 25,400 or so" The D3x (?) and D4 and D800 go to 102,000. Why? If I could 2/3 more "speed" by using a B&W sensor I could achieve what ISO 306.000 or so? Or a clean IS 18,600 or so WHY? This scene is illuminated by the moonlight reflected from my cat's eye? At what point doe it get to be overkill?
