We hope to do more extensive tests in the future to accurately rate resolution, color accuracy, and spot aberrations. It's equivalent to an 11.5mm lens in 35mm film. Fujinon's HAF12B-10 is a 12mm lens that provides an angle of view of 43.34 degrees, which is, in 35mm film terms, a 27.5mm lens. The minimum focus point is .4 meters or 15.75 inches. Fujinon's HAF40B-10 is a 40mm lens that provides an angle of view of 13.4 degrees, which is, in 35mm film terms, a 91mm lens.
Prime lenses are sharper than zoom lenses because there are fewer optical elements and compromises.
This was evident when we compared the images made with the Fujinon 5mm to those produced with the Canon or Angenieux cine-style zoom or the Fujinon servo zoom lens. The difference in clarity was instantly recognizable. All three lenses had the identical color reproduction characteristics. The 12mm and 40mm lenses appeared free of aberrations and distortions. The 5mm lens did exhibit red misconvergence at the left edge of the image area.
