This lens gives the best of both worlds because optics still give full coverage and excellent sharpness on 35mm film. A macro lens that can handle both the digital and film worlds with ease. The ATX 100 PRO D also has a very convenient focus limiter switch that can lock the focus out of the closes focus making it focus faster when used as a moderate telephoto lens that is excellent portraits as well.
