I'm using a rather non-descript black backpack for my 500C/M based
kit. Below a few quick snapshots. The backpack as shown contains
a 500C/M with 45degr prism, a C50 (mounted on the camera), a C80
(top right), C150 (left bottom) and a CF40 (center bottom). There
are 3 A12 and 1 A16 magazine present, one A12 is on the camera.
The free space is filled with miscellaneous filters and a Gossen
meter.
On my last trip I left the C150 at home and took a spare 500C/M
body along, plus a Kodak DC3400 converted to take IR pictures. That
also fits in the bag. With a complement of film (35 rolls approximately) things
got rather stuffed but it is do-able. The overall
weight is less funny..., but it is compact and taking it as carry-on
luggage onto a plane is no problem at all.
