Can't say that i've ever felt a 'bond' with a camera. There have been those that worked better than others, or felt better, but i don't think i've ever had a sentimental attachment to any of them. The closest would be the Hasselblad 203FE.
NO BOND
Leica M7s. Beautiful, solid, a lovely tactile experience, but more frustration than results in use. I tried to love them, but they forced me to work awkwardly instead of working the way i wanted to.
Contax G2s. Beautiful. Lovely tactile experience. But, that viewfinder! I've had a G2 on 4 or 5 different occasions, and after a few months, sold it.
Rolleiflex 2.8F Planar. Gorgeous. Nice Maxwell screen in it. But, the dials were always stiff, and it wasn't as sharp as the 203FE's 80mm Planar. The 203FE was just more practical.
BOND?
203FE
Nikon FE2 — except for hating to have to pull the wind lever out to use it.
EOS 3 — i've had this the longest. It's efficient. But, there's no love. It's not pretty, and it's loud.
Nikon F100. Nothing not to like. Looks great, feels great. Maybe this is it? I had an F6, but in a rare instance of 'sensibility,' sold 'down' to the F100. It's just more practical, and i don't have to care about it so much. And, whatever the F6 has that the F100 doesn't have, i don't use.
Canon 5D Mk II. It was pretty good for its time.
I might have bonded with the Pentax LX, except i found (2 of) them to be unreliable.
