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.
I have a Weston Master Cine Exposure Meter for sale. I've put it on BidorBuy's 'Crazy Wednesday Auction' for this week and came across your website while 'googling' for more info on the item.
The exposure meter model is S74/720 and I also have a 'Invercone incident light attachment'... I have no idea if these items are in working condition... I at least now know these items go together....
May I refer to your website in my auction?
You can as reference to the original advertisement. I don't own, nor have any endorsing or negative opinion about the meter.
