  • Medium-telephoto Lens
  • High Definition Coating
  • Shake Reduction Mechanism
  • Filter Diameter: 67mm
  • Dustproof, Weather-resistant Construction
  • Ideal for portrait photography:
  • When mounted on a PENTAX 645D medium-format digital SLR camera body, this medium-telephoto lens offers a focal length of approximately 71mm (or approximately 65mm when mounted on a PENTAX 645 film-format camera body) in the 35mm format
  • With two ED (extra-low dispersion) elements and one glass-molded aspherical element in its optics, it assures high-resolution image reproduction over the entire image field, while effectively minimizing chromatic aberration, a problem commonly associated with fast lenses
  • At larger apertures, this lens defines the subject with fine, delicate lines and soft, velvety edges
  • Coupled with a beautiful bokeh (out-of-focus rendition) effect created by a very shallow depth of field, it is an ideal lens for portrait photography
  • At smaller apertures, it produces sharp, solid images to make it useful for applications other than portraiture, such as scenic and still-life photography
  • It also offers macro photography at a maximum magnification of 0.5 times
  • In close-up applications, its floating mechanism effectively compensates for the curvature of the field to assure sharp, well-defined images
  • HD Coating and Aero Bright Coating:
  • High-grade multi-layer lens coating called High Definition Coating
  • Compared with conventional multi-layer coatings, this coating offers higher light transmittance with reduced reflection, to deliver sharp, clear images free of flare and ghost images, even under demanding lighting conditions such as backlight
  • By coupling this coating with the PENTAX-exclusive, high-grade Aero Bright Coating, this lens optimizes light transmittance while minimizing refraction
  • Aero Bright Coating is aprocess developed through the use of advanced nanotechnology. Using a silica aerogel with a uniform porous structure as the base material, this coating produces clear, high-quality images by assuring an outstanding anti-reflection performance over a broad wavelength range
  • Lens-installed Shake Reduction mechanism:
  • Uses Shake Reduction mechanism within the lens barrel
  • Since this mechanism effectively compensates for camera shake up to approximately 3.5 shutter steps, the user is assured of sharp, blur-free images even under conditions prone to camera shake, such as when handholding the camera at poorly lit locations without flash illumination, or when photographing sunset scenes
  • Dustproof, weather-resistant construction:
  • All Weather (AW) series; this lens features a dependable dustproof and weather-resistant construction with 11 special seals to effectively prevent the intrusion of dust and water into the lens interior
  • By mounting this lens to a PENTAX 645D camera body, the user is assured of a durable, reliable imaging system that performs superbly in demanding outdoor settings - even in rain or mist, or at locations prone to water splashes or spray
  • Exterior design signifying HD series:
  • While inheriting traditional design features of PENTAX medium-format lenses, such as a twill-patterned focus ring and metal rings, this lens features a red almite ring at the front end of the focus ring to signify the HD PENTAX lens series and enhance its exclusive appearance
  • Other features:
  • Quick-Shift Focus system for instant switching to manual-focus operation after the subject is captured in focus by the camera's AF system
  • SP (Super Protect) coating applied to the front surface of the lens to effectively repel water and grease and easily wipe off dust and stain
  • Rounded diaphragm to produce a smooth, beautiful bokeh (out-of-focus rendition), while minimizing the streaking effect of point light sources
  • SPECIFICATIONS:
  • Focal Length: 90mm
  • Equivalent to 35mm format: Equivalent to 71mm in 35mm format
  • Maximum aperture: f/2.8
  • Minimum aperture: f/22
  • Number of Diaphragm Blades: 9
  • Angle of View: 34° (with PENTAX D-SLR camera body)
  • Construction: 11 elements in 9 groups
  • Smallest object distance/magnification: 0.413m
  • Magnification: 0.5x
  • Filter Diameter: 67mm
  • Dimensions (Length x Diameter): 111.6mm x 90.5
  • Weight: 1040g
