Thanks for the feedback Charlie. It's hard to wrap your head around all of the options available once you start looking at adapting. I think I need to invest in a metabones IV. I still have a metabones III, and it isn't too useful these days since I can't update the firmware.
BTW, anyone know if there are any Nikon adapters that won't fry your camera?
stay away from Nikon, some lenses have mechanical aperture, some have electronic! Some of the focus is screw driven, some not!
you'de need a really advance adapter with very good firmware, and only two good with firmware are metabones and sigma. They dont make anything for nikon, so pass..
I've seen MBIV's on FM for roughly the price of MC-11's. I sold my MC-11 near new for 220, and at that price, you may be able to score an MBIV-T.
the MBiii should still be able to do green mode right? might as well try it.
