Originally posted by dlacouture Well, with manual A lenses, it will work exactly as with AF lenses: select a focus point, then half-press and shoot... It will behave somewhat like a focus-point-center-weighted metering mode, nearly a spot mode...
With old PK, PK-M or m42 lenses, the camera will revert anyway to center-weighted (matrix mode will be unavailable).
There is still a trick to get it to work : you have to short the A pin on the mount. the camera will be tricked into thinking it has an actual A lens currently mounted. But you'll then have metering problems in Av mode if you're not careful, and some other problems...
Do you have more info on what other consequences of shorting the A pin in the mount?
Thanks,
