    Tracy, looking forward to your findings!

    It's possible to make a Av-xenotar 150mm 2.8 fit in a copal 3s shutter. I know becouse I have made one. The lens formula is not that of a xenotar, it is more like an altered sonnar. The image circle is about 127mm at infinity. So no 4x5. For portraits however, you do get the 4x5 coverage.
    Waiting for some last parts to ad a filter thread to the lens and then selling it. Fantastic lens. Also good for close-up/macro photography (with the aperture behind the 4th element)
    Ask me anything if you have a question about this lens.

    I realize I never updated the forum on this. I shortened the tube on the back of the lens, and it seems like it will cover 3.25" x 4.25", but can't be used on the Graflex (nor on my Plaubel Makiflex) as the back focus is too short, something like 3.75" from the rear element to the focal plane at infinity. It COULD be adapted to a Pentax 67, I suppose. I will probably eventually mount it on one of my 3.25 x 4.25 Speed Graphics.
