Hi all, I have never been 100% happy with my k7 and so have started to play with my old z1p again.
I have recently come into a couple of old manual lenses and so have been thinking more about how the mechanics work.
Specifically, how does an old manual lens tell the body what the aperture is? I know that the aperture sensing ring is there to do that, but is the mechanical coupling that precise? And how does the body know if the open or closed settIngs on the ring relate to a 1.4 to 22 lense or to a 6 to 32 lens? Does the ring have a given setting/position for each f stop? If the body knows the aperture why does it not show it on the LCD?
It's fun thinking about all this stuff again!!!!
Thanks in advance!
Brett
