I just got my NN3 II in the mail today (and I must say that it is of better quality than I expected for the price, hats off to you!)
so I was trying to get my entrance pupil setting for my D50 + sigma 10-20mm lens. I could not tell using the "gap" method of lining up a close and a far item and seeing if there was a gap. What I did was line up the corners of two houses. I put one directly behind the other so I could just barely not see the far house. Then I rotated the lens away and the other house came into view. Then I moved my camera down the rail until the house disappeared. now the left rotated view looks exactly like the center view. This seems like just as good a way as any (maybe easier) does anyone know of any reason why this would not work I have a 360 tour to shoot tomorrow and I want to be ready.
