I'll be dusting off my old 35mm camera kit this weekend to see what I can reuse with my new Nikon D90. Back in the 80s I built up a nice little 35mm SLR system consisting of a Minolta Dynax 7000i camera with stock lens, a Sigma 300mm zoom lens, a flashgun, etc. All of that is housed in a nice gadget bag than I may salvage.
I also have two Hama tripods (with spirit levels), a desktop tripod, a mini-vacuum cleaner (battery=powered), and, most importantly, a box full of Cokin filters (around 50 in total). What are the chances of reusing the Cokin filters with the D90? I think I spent a fair bit of cash on them back then and anything that I can salvage, I will.
