For many years I've happily used the Spotmeter F at home for my personal work and my inherited Pentax Digital Spot Meter at work. I get along fine with either one, but truth be known I like the Minolta best.
So I brought the Minolta to work and both meters side by side and discovered that with the Minolta set at ISO 400 a reading of 1/30th @ f22 gives EV 14. So if I set the Pentax front ring at 400 and set the 30th at f22, I look at the EV scale and it says 12.
So what gives? I can get a good exposure from either meter but that's a perceived 2 stop difference.
