So, I wanted a D700, looked for a D700, found a couple of pre-loved D700's . . . and bought a D600.
It popped up out of the blue, only 200 clicks, guy needed the money and had the invoice to prove he owned it . . . and I was happy with the price.

First day out was Saturday arvo for the local hockey 1st Division game and . . Nooo! Its under flood lights!!
As good as the D300 is, I could never get decent images with it under these rotten lights.

The initial settings wasn't hard to set up. Pretty much copied what I used with the D300 - along the line of, turn everything off and just turn on what was needed.
With one exception, I turned on auto-ISO. Yes yes, I know . . its an 'auto' function and by doing this I'll go straight to the gates of the damned . . anyway I did it and I'm pretty glad I did!
