Gee, what a load of really good info, after less than 24 hours after I made my post!
My thanks to all who have posted AND who will post. I was originally going to PM the APUGgers who replied, but, time constraints being what they are, I will have to cop out and make this posting instead.
I should have mentioned that my Nikon Fs have the plain, non-metered prisms, and that I haven't owned a camera with a working TTL meter in 32 years. To tell the truth, I haven't felt the loss; I swapped my last camera with a TTL meter, a Nikomat-EL, for a Graphic View camera and accessories in 1978.
I use a Gossen Lunasix-3 meter, usually in incident mode, when I use a meter at all. I estimate the exposure, and, on rare occasions, have ACTUALLY produced properly exposed frames; I was printing one of them last night, as a matter of fact. I had to search in my lamp stash to find a 75-watt bulb for my D-6!
As I tell a painter and sculptor friend of mine, who is attempting to learn photography, when one wants to calculate proper exposure, one must FEEL the light!
