    Re: 8x10 Portrait Lenses

    The Acutar is essentially a Commercial Ektar. Given a choice between the two, buy on price and condition.

    Re: Swapping the pinhole with a lens

    Laci, you floated this idea on photrio.com.

    Short answer, you need a camera back with a ground glass in register with the film plane. You don't have to use the GG when shooting, but you need to...

    Long. It is a 500 mm lens of normal construction, will want ~ 500 mm extension to focus to infinity. Closer will need more.

    Re: Confused by lens math

    The aperture measurement to use is the diameter of the entrance pupil. Open the diaphragm wide, hold the lens at arm's length, front facing you, and measure the diameter of the aperture's image.

    Re: What am I doing wrong?! Mounting Copal 3
