    High resolving power combined with outstanding maneuverability to be the perfect partner for PENTAX full-frame digital SLR cameras

    Despite its compact, highly maneuverable body, this versatile zoom lens is designed to accommodate the image circle of a large full-frame image sensor, thanks to the adoption of state-of-the-art optics and high-performance optical elements. When mounted on PENTAX 35mm full-frame digital SLR cameras, it delivers high-resolution imaging power as an ideal everyday-use lens.


    Aero Bright Coating

    Aero Bright Coating is PENTAX's newest lens coating developed from nanotechnology. It uses a silica aerogel coating layer with uniform porous structure applied over a regular multicoating. This traps low-refraction air between stable silica nanoparticles for enabling a coating with super-low refraction rate and high transparency. The coating has greatly reduced surface reflection. In addition, using a new super-low refractive index layer formation process, we have developed Aero Bright Coating II, which enhances low-reflectance properties.


    HD Coating

    Typically, multicoatings are formed by using vacuum deposition to apply a thin layer to the lens surface. However, this fabrication process also presents problems because of the difficulty in increasing the density of the coating film and the variation in refraction rates and film thicknesses. PENTAX's solution to these problems was our HD Coating, which is fabricated using PENTAX's exclusive special fabrication process, where high-density film is applied with high precision at the nanometer level. This enables the reliable formation of the designed film thickness for a dramatic reduction of the reflection rate (up to 50% compared to conventional coatings) over the entire visible light range. It is also effective in reducing ghosting and flare. Moreover, the film coating has an extremely high hardness for providing superior durability.


    Special Optical Glass

    The refraction rate of glass varies depending on the light wavelength. For this reason, because natural light consists of light of various wavelengths, this light fails to converge to a single focal point when passing through a lens. When an image is enlarged on a computer screen, you can sometimes see purple blurring around images of red points, for example. This is called chromatic aberration. In typical lenses using optical glass, this is difficult to correct as the focal length becomes longer. To minimize the chromatic aberration, PENTAX uses ED (Extra-low Dispersion) Glass, Anomalous Dispersion Glass, and high-refraction low dispersion glass, all of which have low spectral dispersion of light beams. The appropriate glass types are used for attaining exceptional imaging performance in both telephoto lenses and wide-angle lenses.

    Description

    Versatile zoom lens covers standard to medium-telephoto ranges. It provides a maximum aperture of F3.5 - 5.6 over the zoom range. Constructed to reduce various aberrations including color aberrations while providing high contrast and high resolution throughout the entire image field at maximum aperture.
