If you weren't using so many different camera systems (but may work with a few simple adapters, too), the Wallace Expodisc (sp?) is a simple device to have in your bag. It is a milk glass cover with a dispersion grid that goes over your lens end, allowing the camera to be pointed at the light source and returns an incident reading. I bought one many years back and had forgotten about it until recently. It's amazingly accurate and about the size of a screw-in filter. It's probably best with a single system/common filter size sort of application, but if your various lenses and metering systems were compatible, it's a pretty slick solution.

I acquired one some time ago. To have precise readings though, you have to follow the instructions and compensate in some situations. I have not been farther than reading the instructions...
