Can someone please teach me how to use the meter on the Sony A900? Honestly, I don't have a clue and can't seem to figure it out. The histogram is spot on relative to the captured file, but if I try to use the meter reading from either a Sekonic 308b or Pentax spot meter, the resulting image is way overexposed. FWIW, the two hand held meters agree. If I use the in camera meter on aperture or shutter priority, the results are all over the map, but tend to be dark. The only way I get the expected results are with the in-camera spot meter and placing the metered value where I think it should fall. Lenses include both chipped Minolta as well as Leica and Zeiss with un-chipped adapters. The results are the same.
What am I doing wrong?
