Hi, I have had my D300 a couple of years now, & dare I say, I am still 'learning'. I used the spreadsheet from here as a basic set-up, & changed the odd setting as I needed etc. I also bought Darrel Young's 'Mastering the D300' book, & when I go away, the manual & Darrel's book go with me. I actaully won a local newspaper photo competition from one of my wildlife images. I bought the 18-200 VR lens with the body, & love it, & have just bought the 50 f1.4 AF-S lens for portraits. Then there was the SB 600 flash, so as to use Nikon CLS, brilliant. It will be never ending to buy things!! Enjoy the camera...you won't be able not to like it. Regards.
