#### Previous Camera Gear ####
… As a young teen, I had a Kodak 608 Tele-Instamatic 110 camera.
… My first 35mm camera was a Rikoh 500 Rangefinder, that I bought used in 1977 or '78, from an Uncle who bought it new in Japan, when he was there in the early 1960s. So that camera was about the same age as I was.
… During the late '70s, while I was in High School, I also borrowed my best friend's Nikon FM or FE a few times.
… In 1981 or '82, I bought a used Pentax Spotmatic 1000, along with used 28mm, 55mm, & 135mm M42 screw-thread lenses.
… When the Pentax was stolen in 1983, my parents and best friend went in together, and got me a Nikon FE2 for Christmas that year, along with a Tokina AT-X 28-85mm f/3.5-4.5 lens. I used that camera/lens combo, along with a Vivitar flash, up until 2000, when I bought a 2nd, used Nikon FE2, which came with a MD-12 motor drive, three Series E lenses (28mm, 50mm, 135mm), and a small Nikon flash.
… In 2001, I bought a new Tokina AT-X 24-200mm f/3.5-5.6 Zoom (auto & manual focus), and a used Tokina AT-X 100-300 f/4 Zoom (manual focus), and Nikon 1.4x & 2x (manual) Teleconverters, to have a compact(?) 2-camera/2-lens setup to use on a vacation trip to England, Scotland, & Ireland. The September 9, 2001 terrorist attack occurred just before our trip, so instead of the big camera bag with a lot of gear, I simplified down to a smaller bag that held one camera body w/MD-12 motor drive, the two lenses, two Teleconverters, polarizing filters, and the Vivitar flash.
… My first digital camera was a Samsung Digimax L55W Point-and-Shoot, which I picked out, and my parents gave to me for Christmas of 2005.
… I bought my first DSLR (Nikon D90) in 2009, followed by a D7000 (which a friend's daughter now has) in 2011.
