just perused this entire thread, and i just had a few questions about this camera i recently aquired ( http://whitemetal.com/pentax/spotmatic/index.htm )
what is the panchro, empty, and color function: http://whitemetal.com/pentax/spotmatic/spotmatic03.jpg'>
also on the base of the lens, it has an auto/manual toggle, what does this do? http://whitemetal.com/pentax/spotmatic/spotmatic05.jpg'>
also just for clarification, with the f-stops, you want a lower f-stop in low light conditions, and a higher f-stop in bright light correct?
