Good evening,
I just picked up a Sinar P2 from KEH and I haven't put any film through it yet, but I've been trying to learn the hyperlocal scale system and determining tilt angles before burning up any film with mistakes that may happen. I think I've got it but just wanted to ask for clarification in case I don't have it. The manual is not exactly the greatest but I did make an attempt to read it multiple times. At first I was actually playing out all the steps one after the other and it obviously wasn't working but then I think I had a moment of clarity.
This is where I am at so far: With all movements and the fine focus dial zeroed I set the hyperlocal dial (on the fine focus knob) to the notch for 4x5 then I focus on the far and reset the dial to the notch then focus on the near, I take note of the aperture it lands on, then take note of the tilt degrees showing on the standard for the fine focus, then back the focusing knob off by 2 stops on the hyper focal scale. Once that is done I set the indicated tilt angle on the lens standard and set the aperture to the suggested working aperture (F stop suggested prior to backing off by two stops) and in theory there should be optimum depth of field and plane of focus set at this point? Is this correct?
This is not my first large format camera but it is my first Sinar with geared movements. I'm sure someone will come along and say that It's just as intuitive doing it without the Sinar system, and it may be, but I figured it has it so might as well learn about it. Any insight is appreciated!
Thanks!
