Thanks for your answers ! In an ideal world(camerawise) I could mutual exchange lenses and bodies; my beautiful G2 + 28 & 90mm > FM + 1.4:85 > RZ67+50+110+180+250 > SL66SE+80> Praktica MTL-3 + 1.8:50. Or am I dreaming of a world that never exists ? An Eden where Eve hates apples ? I know the shutter is in the lens; but is there a way to get around that ? Didn't know SKGrimes: thanks. "why bother"? just because
