I did so, but either I don't understand what the manual says, or I am doing it the wrong way.
Is the exposure memory actually the exposure lock on the A-1? Or is it just to hold and alter the shutter/aperture from the dial? Does anyone know how it is being used?
Also, for the other switch, the exposure preview one, there are not many words other in the map of the camera in the user's manual.
--- Edit ---
Upon more carefully reading the manual I have discovered that:
1. The exposure memory locks the EV of the exposure and not just the shutter/aperture pair.
2. The exposure preview switch just makes a reading of the exposure in the viewfinder.
Read the damn manual. The million dollar advice that me not follows every single time!
