No, Shannon. Not a telephoto. Just a long lens. A telephoto lens of
30" focal length will physically measure maybe just 10".
If you load your 8x10 holder with a piece of 35mm film and put it
behind your 12" lens, you'll get a narrow field of view, but the 12"
lens would not have transformed into a telephoto lens.
