I haven't used it since I have an incident meter -- two actually. :) But it should work fine. There is a fixed relationship between a reflected meter reading from a gray card and an incident reading of the same light -- I don't recall how many stops and am too lazy to go look at my meter that shows the difference. If I correctly understand how it works, the expo-disk snaps over the lens and blocks that amount of the light so when you point the lens at the light source the in-camera reflected light meter becomes, in effect, an incident meter. Sorry to see from the web site that the inventor, George Wallace, died last May. He used to hang around the Compuserve photography forum and seemed to be a nice guy, if a little fanatic in his view that everybody should use an expo-disk. :) Bob - This message is from the Pentax-Discuss Mail List.
