My Recommendation: There are so many availablefunctions here that I’m loathe to recommend anything. Peopleshoot in so many different ways, and there are so manychoices in this list that it’s hard to pin it down to just a few.However, I will tell you what I set mine on, and you can thenexperiment and see if that suits your style too. If not, you’vegot a lot of choices!My favorites:▪ Assign Fn (FUNC.) button press – Spot metering (Mynormal meter is Matrix).▪ Assign Fn (FUNC.) button + dials – Auto bracketing.▪ Assign preview button press – Preview (depth of fieldpreview).▪ Assign preview button + command dials – None (I don’tuse this).▪ Assign AE-L/AF-L button press – AE lock only.▪ Assign AE-L/AF-L button + command dials – Choosenon-CPU lens number.I hope you’ll experiment with each of these settings and see ifyou like others better. Nikon has given us amazingconfigurability for our assignable buttons, so why not testeach one?Customize Command DialsCustom setting f8 (D300S) and f7 (D300)(User’s Manual – D300S page 297; D300 page 308)409
