hehe. to be honest, the reason i am thinking about making the switch again is that my shooting has changed. last time i made the switch, i was mainly a birder so the big super tele's were a must. now, i mainly do portraits and events so i have no need to spend 8k for a 500 F4. i still maintain that body and zoom lenses wise, nikon is the winner and honestly, the D700 that i had was the best body that i have ever owned (FF, Pro-AF, fast with great IQ? whats not to like). now that i only need a D700 and a few lenses (24-70, 70-200, 50 1.4 and maybe 1-2 more), i am very tempted to make the switch.
