I have an old Gossen Luna Pro light meter from the mid 1970s and am remembering how much I loved it and relied on it back then. I'm thinking it might turn out to be quite handy using older lenses on these newer cameras - when one is in a more static mode of shooting for architecture or portraits, etc. In searching quickly via the Internet, I see that I'll need to get a adapter kit for the batteries...but it appears that B & H sells them and they work well: http://www.bhphotovideo.com/c/product/89868-REG/Gossen_GO_4145_Adapter_Kit_Battery_Holder_for.html Do any of you use hand held light meters and if so which kind? I suppose, I'm a throwback to the earlier days, but I get the sense I'm not the only one on the site. Any thoughts or reactions welcomed.
