I was told by marc Sabatella and Gordon Goode, that Gordon had done some tests, and that after ISO 800 on the K100, they weren't adding any amplification in the analog circuitry, that 1600 and 3200 were just shot at 800 and adjusted in math. So, if you're shooting raw, shooting over 800 doesn't gain you anything, and that you're better off shooting at 800 and underexposing (where you'll at least have more headroom ) > > On Fri, Jan 28, 2011 at 10:23 AM, Darren Addy <[email protected]> wrote: >> On Fri, Jan 28, 2011 at 9:10 AM, David Parsons <[email protected]> >> wrote: >>> Faster than 2.8 would be nice, but it's not that much of a problem. >> >> If you think about it in terms of film, we are in the best shape in HISTORY. >> When the Pentax-A series of lenses was available, 800 was probably the >> fastest ASA/ISO in general use.
