The Westone Master II with the Weston Invercone*
Here's the meter that answers every exposure problem. . . indoors or out, with any camera, any film. With your Master you can determine correct exposure quickly and easily, using either the reflected or incident light methods. When the incident light method is preferred, simply snap the Invercone* incident light adapter over the photo cell. If you own a Master (Mod. 715 or 735) ask your dealer to demonstrate the Invercone.

My photography instructor has one of these, or a very similar model. I'd really like one--they seem very robust, and easy to use.

Yup. They worked for Ansel Adams, and he never seemed to have many problems getting the right exposure.

i have the very similar Master IV, calibrated last year. nice, pocketable meter, especially good for incident use w/ the cone, and batt-free too.
