    This is a fast F1.4 aperture standard lens for digital cameras. SLD (Special Low Dispersion and ELD (Extraordinary Low Dispersion) glass elements are used to obtain the best possible correction for magnification and chromatic aberrations, which are particular problems for digital cameras.
    From 40cm (15.7”) minimum focusing distance to infinity, this lens creates very sharp images with high contrast. The

    HSM models provide quiet, high-speed auto-focus shooting, as well as full-time manual focus override. Large maximum aperture of F1.4 can perform superbly in a great range of applications, including snapshots, portraiture, indoor shooting and landscape photography.

    This lens is perfectly suited for a wide range of subjects, portraits, indoor shootings etc. It is fast aperture makes this lens desirable for use with Digital SLR cameras. The shallow depth of field produces an outstanding image, sharply outlined from the blurred background.

    Two SLD glass elements are especially effective in the compensation of magnification chromatic aberration. A molded glass aspherical lens at the rear lens group reduces colour aberration and provides high-quality image results.
    The HSM design provides quiet high-speed auto-focus with full-time manual focus override.

    The lens creates exceptionally sharp images of high contrast from its minimum focusing distance of 40cm to infinity. The large maximum aperture of F1.4 produces a versatile lens that performs superbly in a great range of applications including portraiture, indoor and studio work and landscape photography.

  • MTF (Modulation Transfer Function; modulatieoverdrachtsfunctie) is een van de metingen die worden verricht om de optische prestaties van een objectief te bepalen. Men meet hiertoe het beeldcontrast bij verschillende ruimtelijke frequenties (lijnparen per millimeter).De horizontale as is verdeeld in millimeters en toont de afstand van het midden tot de rand van het beeld. De bijbehorende contrastwaarde (maximaal 1) is uitgezet op de verticale as.

    De waarde bij 10 lijnparen per millimeter geeft het objectiefcontrast aan (rode lijntjes). De zich herhalende fijne parallelle lijnen bij 30 lijnparen per millimeter geven het scheidend vermogen (scherpte) van het objectief bij de volle opening aan.

    De zich herhalende fijne parallelle lijnen die in de diagonale richting van de ene naar de andere hoek van het beeld lopen worden Sagittale lijnparen (S) genoemd. De lijnen die daar loodrecht op staan worden Tangentiale lijnparen (T) genoemd.
