Here is my little contribution to PV. These focus by wire lenses are maddening. So, I've been trying to finda way to manage repeatable focus moves. Here's where I'm at: Physically superimposed marks on the LCD or monitor. (Stick on) I first tried camera tape strips with pen marks. Not bad but ugly. Also grease pencil and so forth. What I came up with (and could be improved is this: (see photo) screen protectors for cameras and Iphones havee a little scale for cutting with precision, I just cut off the scale and stuck it over where the distance slider appears when you manually focus an auto lens. It's transluscent with marks and numbers. Then I used the focus chart and tape measure and memorized distance for each auto lens. (sort of) It could work for your focus puller, or piss her off. But i like it for hitting a couple of marks without spazzing out on the focus ring. It's something. With the 12-35 pana, it could be promising eh? Photo taken with camera phone looking into the varavon loupe diopter, mounted on gh2... Good Loupe! Thanks Vitaly Let's get 'er in focus dammit!
