It isn't the type of meter you have...it is how intelligently you use it.
My Minolta IV meter is no more accurate than the meter in my camera if Ipoint it in the wrong direction......so provided you know how to use the one in your hand, whichever it is, you will get good results. Even in split lighting situations like DD mentions, you can use the camera and interpoltae, in that situation the Minolta has the ability to take the two and average them...little marks like this ' ' ' come up on the f stop bar at the top. One for shadow reading, one for highlight reading and the in between "average" which should provide detail at both ends provided the range isn't too great.
Out of interest, why do you ask?
