I have a digital Minolta IIIf Autometer. It only shows one reading at a time and you have to hit a button to move the readings to select another setting. The problem is this meter is shutter priority. So you'll get digital percentages of apertures like f/8.7. There's no selection to make it an aperture priority. I suppose that makes sense because, with old film cameras, you can't get shutter settings other than at full stops. The more modern digital meters allow you to set aperture priority as well.
That may be an improvement, but IMHO, that's still a PITA to have to keep pushing buttons. With the two scales always available -- on most non-digital exposure meters -- all the options are right there for you to see, all at once.
