Luna Pro SBC When my old Luna Pro died and the repair would cost more than the replacement I opted for a newer Luna Pro SBC..I must have looked at the wrong illustration for I ended up bidding on not a zone dial Luna Pro but the null meter SBC model. Something I have come to know and hate! I am analog to my bones and can transpose a dial with numbers into zones in my head. But the null meter principle totally confuses me And using the Gossen Spot attachment from my old Luna Pro is even worse if that is possible , nothing computes. As the joke goes by the time the exposure was figure out the glacier had melted. Instead I wipe out my trusty Weston Master V and get a reading that makes sense Oh I have the manual and studied it , no help there. Now some people love the latest things, I am not one of them If anybody wants to swap an old working Luna Pro with a regular dial and needle with numbers for a reasonable new SBC in very good working order, I would be interested. I never considered a spot meter as I dont want something so bulky I need a holster to carry it. instead of slipping it into my pocket.
