  1. Hi Ted,

    just curious, what is the focal length of the new 50FL lens? is it same as the 50mm Achromatic (250mm)?


  2. Pavel,

    It’s 400mm f.l., F8. So more intended for nature photography including lunar and solar imaging. Fluorite, 50mm aperture and F8, virtually perfect corrections as you can imagine. It’s so sharp indeed.
