People don't trust themselves to do it. I spent a lot of time checking my focus on "ground glass" vs microprism and rangefinder type thingies in the viewfinder. Eventually, I could pretty much agree, and sometimes disagree. Disagreements are usually in my favor. I now abhor any focusing aid that takes up a lot of space. Suckers blank out in dim light. I'm glad I did my experimenting, but I did not trust myself at first. I'll bet anyone with a long memory didn't, either, if they can remember that far back.

Focussing aids? Oh yes, I remember those. I think my ME Supers have them. Horrid little devices. Whats wrong with just focussing until the subject is in sharp focus?
