I'm reading a lot about this "Green Button" and how to set up it's functions... alas; my K-100D has no such GB, and seems to have assigned it's functions somehow to either the "pre view" stop on the power switch that goes around the shutter button or the little square "Av" [+/-] button located just SouthWest of it.
Have experimented with these but can't really tell what effect they have on exposures (if any) and they don't seem to help matters any.
About the only luck I've had thus far is using a screw mount 35mm WA pre-set lens with M42>Kmount adapter and setting "M", setting aperture the old fashioned way.
This set up has been the only way I've been able to use the flash to get a decent picture.
I've noticed that using "Heritage" lenses on this DSLR (don't know if it universally applies) cuts field of view / picture size down considerably, making them to some extent "Narrow Angle" lenses. This WA somewhat compensates for that phenomenon but not quite as much as I'd like it to.
I still have to guess at the exposure settings though; if there is a TTL light meter in this camera it would be helpful, but I have yet to find it. Any suggestions?
