I tried posting this in the beginner's forum, but haven't gotten any responses:-|...so i figured i'd try here.. Ive never used a Depth of Field scale. But I am reading about it right now. So I'm curious...;-) On the lens, how do you know which aperture matches with which distance? Are the apertures matched to the appropriate distance by color? Maybe that sounds confusing.. I mean.. For example.. Let's say f/5.6 marking (on the lens) is PINK , and 7ft distance marking (on the lens) is also PINK, so they match. Is that how it is?
