I recently discovered two Darlot projection lenses that go with my Magic Lantern projector. Here are my questions:
1. Is there anyway of using these on a 4x5?
2. If I wanted to have a flange made for a lens board, how do you measure the threads etc.? Or is there a place that might have them?
3. How do you know what the focal length and aperture are? (there is no aperture iris or waterhouse (?)
4. Is this lens anything like (results) of an antique portrait lens?
I'm just learning about these things. I love the look I'm seeing with the tintypes & wet plates, and am wondering if that can be achieved with normal negatives when using a lens like this.
Thanks in advance!
