DIY Light Meter Sensor Quesiton

I've got a 50mm Nikon lens with a bad blade,,, hummm. Was looking for a broken spot meter to use as a base, with the splitter already built. How about building the thing into one of the 620 film Kodak TLR's, or even an Argus C3?

I'll go back thru the thread and take a look at the software and PIC side now
