The Cameras and The Lenses

Olympus C-750 Ultra Zoom, from 2004 to 2006.

Canon EOS 350D, from 2006.
Lenses; Canon EF-S 18-55mm, Canon Zoom Lens 55-200mm.

Olympus µ 770 SW, from 2008.
(I mainly use it to take photos of fireworks and tadpoles in an aquarium, since I find it useless for most other things.)
