In or around 1975, my Canons were stolen and my wife bought me a xmas present Nikon F2 along with a 105 2.5 and 50 mm fl.8. I never looked back. The f2 is the ultimate "tank" design. AFter the F2 was stolen around in the early 80's, insurance replaced it with the F3, which I used everyday w/o a single problem until 2000. Traded the F3 on the F100. Meanwhile, all my old nikon lenses continued to be fit the newer bodies--including the N70. I still have and use the original 50 1.8 and the 105 2.5.
Also, Nikon -- like Leica and Sinar--has a reputation for being the best. Nikon is a player in the history of 35mm photography in last 40 years.I never "wish" I could "move up to the best." I"ve got it.
