Please excuse my ignorance. I never shot screw mount lenses or K mount on film SLRs; but used only FA lenses. Once I moved to digital (100D Super), started exploring more on these other avenues and hooked up to these m42 glass pieces. (read addicted). At the same time, using more of "M" mode and meter reading is taken from so called GREEN button (AE/L button). Now I just want to dust out my film SLR and try these takumars on them. Surprise, no green button on earlier camera
. How to shoot or take meter reading for these combination?
* Try rough readings in Av mode and switch to M mode and adjust as per the choice or any other methods?
thanks in advance
