Since updating the firmware on my D300, I hadn't have had a chance to try it out. But I had read several post on how some thought it improve WB and AF etc. So tonight I finally had a time to try out a few things... It feels that the AF does work better in lower light but need to try this a bit more to be totally convinced that it is. But the main thing that I noticed is when I switch from 12 Bit to 14 Bit RAW, the shutter lag that I use to experienced seems to be virtually gone...:smile: Still not as fast as 12 bit speed, but very close, almost indistinguishable between the 12 & 14 Bit settings.... IMO I feel it has improved heaps.... Has anyone else noticed this...???
