I have an autoreflex T2 and my metering seems to be backwards.... For example; I will set and frame a shot at say, a shutter speed of 125. Now let's say that the meter says to use f4. Now, if I slow the shutter speed down to say, 60 it will then say to use f2.8. slowing down the shutter speed is already letting in more light, why open up the aperture more? It's backwards. (the reverse of this example is true too) So does anyone know why this is happening or how I can fix it?
