Wista 10X8 plate. (Rarely used as its £50 a click)
Hassleblad medium format for portraits.
Lieca and Pentax SFK for 35m slide/print
Olympus for digital (soon to upgrade again to Nikon)
standard webcam without the plastic lens for astronomical telescopic stuff

Looks like my search is getting closer...i might just go for the Olympus E500!!!
