60-series focusing screen versus 80-series?
As I understand it, replacing the 80-series focusing screen in my K10D with a 60-series screen will significantly improve metering accuracy with legacy M-42 lenses. Before I spring for a LL-60, can anyone tell me what happens to metering with my FA and DA lenses when the LL-60 is in place? I am particularly concerned about metering performance impact on fast lenses such as the FA 50/1.4 and FA 70/1.7, but experience with any and all lenses, including MF "A" lenses would all be of interest. Thanks, in advance.
