Well I use Canon. I have one EOS30 and one 30v, the 30v replaced my 33 which is dead.
My favourite lens is my 24mmf1.4L Sometimes it seems like it's the only lens I use.
Previous to the 30's I used a T90.
I guess I'm stuck with Canon, once you have got together a certain number of lenses, well I'll never change now.
I've always had Nikon's ... F2, F3, N70, N80, F5 - I still have all except the N70, the F3 is junk and has been a paperweight for years, the F2 has a stuck shutter and a broken meter. My primary camera is now my Toyo 45AII.
Oh... Memories of my first 35mm camera. The Yashica TL Electro X. Sitting at the bottom of the secret water reservoir outside Los Alamos NM - the reservoir used by the Manhatten Project. Dropped it 25 years ago.... *Sniff*
Nikkor lenses is why I bought into the Nikon system of cameras, not the other way around. There are a lot of things about Canon bodies that I like over Nikon, but I just love the "look" I get with Nikon's glass.
