The first camera I had the use of was my Dads Canon FTQL.
Then my Sister got an EOS 1000FN which I had access to (and so I could teach her how to work it)
When I started working in a camera shop as a student I was able to pick up 2nd hand gear cheap, and went through a 5 (A2e) a 50e, a 3, a 300x (still have the last 2)
Digitally my first Canon digital (2nd digital, had a Sony FD88) was a Powershot s40, I still have a sx630HS in my glovebox.
DSLR wise I sold every Canon DSLR from the 10D, original 1D to around the 30D, when I graduated and went into FT employment in education, then production, and now freelance.
I currently have a 60D, an M, a 400D, a 20D and a 10D (I love the 10D for it's build and handling, it's a beautiful camera to hold and control, if frustrating to use, just in terms of speed) but I've owned a 7D, another M, 3x 600D's, a 550D, another 400D..
I'm on the cusp between Panasonic and Canon, using their m43 4K cameras (with speedboosters) for production work, but still leaning on the Canons for stills.
If Canon can launch a resonably priced 4K option with similtaneous monitoring (even if just SD or HD monitoring) then I might re-commit to Canon fully.
