Hi folks
I've been looking for a Compur #1 to put my Pullin Pulnar 2.8/100 in and the price for one on it's own was too much for me, but I found a mint working one with a Symmar 5.6/150 in it for a real bargain price.
Now what I need to do is recalculate the aperture scale for the Pulnar.
150/5.6 = 26.79
100/2.8 = 35.71
The aperture does open up a fair bit wider than the 5.6 mark on the scale so 2.8 should be possible.
I'm just not sure how to go about redoing the scale. The 5.6 mark doesn't correspond to an easy aperture with the 100mm lens - 100/26.79 = 3.73 so with the 100mm lens, the 5.6 mark corresponds to f3.73. The f8 mark would correspond to f5.3.
I would like to do this without spending any money, so I hoped I could just put a sticker over the existing aperture scale and mark on it 2.8, 4, 5.6, 8 etc by using the existing scale as a guide, but it seems it isn't going to be that simple.
Any advice as to how to go about doing this?
