Did Ashton Kutcher influence your decision to buy Nikon?
No, not only did I make my decision to buy Nikon as my primary camera system years before the kid was born, I actually bought my first Nikon (F2 Photomic w/ 50mm f/2) almost 4 years earlier. By the time he was hatched I had 2 bodies and 4 lenses (3 Nikkors).
I've owned brand cameras (Leica, Canon, Mamyia, Minox, ...) off and on for years, but I've had Nikons as my primary camera(s) continously since early 1974. The decision to move to Nikon, from my old Miranda G, was made a number of years earlier but had to wait for me to get a solid job after finishing college.
