I've never compiled a list of our cameras and lenses except for the insurance policy... but we just recently joined Canon Professional Services and had to list and add the serial numbers of all our gear. For those who are curious- this is the whole list of our Canon camera and lenses. We use the Canon system for 99% of our work because it's amazing gear and shoots just about everything really well.
We also own a medium format Contax 645AF camera with a 80mm lens and 140mm lens. I still use this camera for super long exposures of star trails. It sees about 1 or 2 rolls of film per year, so it's always a surprise when I get that film developed! :)
I also still own a couple Nikon cameras and a few lenses, including my first ever SLR camera the "Nikon FA" which still works great for long exposures because it doesn't use batteries on the bulb setting.
I still own my original Nikon F5 as well because it's very sentimental to me! I put thousands and thousands of rolls of Fuji slide film through that camera. That thing was a workhorse! 8 frames per second, and 8 AA batteries... shooting sequences of snowboarding and wakeboarding it would burn through a 36 exposure roll of film in less than 5 seconds! At 7 bucks a roll for film, and 8 bucks for processing, that was expeeeeeensive! Starting off with film definitely gives you a whole different appreciation for the digital age.
We of course have tons of accessories and random little things, but that's a whole other blog post. :)
I don't have photos of the Contax and Nikon cameras right now, but here are all the Canons! Feel free to ask technical gear and camera questions in the comments, I don't mind at all and would be happy to help out with any opinions.
