My current Canon inventory:
F1-n, with motor drive and speed finder (2" eye relief, swivels for waist level viewing- great for macro work.)
Canon FD 200 f/4 Macro
Canon ML-1 Macro Light
EOS Elan 7, with the kit lens (28-90?)
Canon Pro 1 - my first real digital camera. It's a real gem for a P&S, as long as you can live with ISO 50.
I outgrew the Pro 1, and took the plunge for the 20D. I didn't buy the kit lens, instead opting for the 17-40 f/4 L and 70-200 f/4 L.
I've always been a big fan of ultra-wideangle lenses. I used to own the Canon FD 14 /2.8 L, and felt handicapped by 17mm on a 1.6x body. So I added the 10-22 EF-S, and a 1.4x TC.
Then I started doing some stage photography, which requires fast lenses. So, I added the 28 f/1.8 and 85 f/1.8. Great little lenses to have around, especially for cat pics.
My latest addition is the only non-Canon lens I have ever bought for any of my Canon cameras, in 23 years of shooting Canon. I needed a macro lens, and I wound up buying the Sigma 150 /2.8 macro. Fantastic lens, at a great price. And, it includes the things Canon charges extra for now, like hoods and tripod rings.
I still have a few items on my wish list, like the battery grip, vertical finder, a long telephoto, macro flash....
