OK two more strange questions for you.
Looking inside the camera are the rollers chrome or black?
#2 when you bring the focus all the way in, as for infinite, is infinitie in focus? Or do you have to take crank the lenses back out just a tiny bit to get infinite in focus?
The second question is because on the 2 FXs I have used, both of the focuses needed to be out a little for infinite. I had to send the camera I kept into harry fleenor to have the infinite focus set so that all the way in was at infinite focus.
Also I don't know if you are happy with the focusing screen in your GX but I was not happy with the stock FX screen at all. I had it replaced with a Maxwell screen and it was much much better. two muches.
