(From Pentax lens literature) Pentax SMC DA* 60-250mm ƒ/4 ED IF SDM


  • When mounted on a Pentax digital SLR camera body, this zoom lens provides focal lengths from 92mm to 383mm in the 35mm format. The 4.2X zoom ratio covers a broad telephoto range, making it ideal for capturing sporting events and portraits.
  • Two extra-low dispersion (ED) optical elements are incorporated into the lens to minimize chromatic aberrations. A unique nonlinear shifting system in the zoom mechanism effectively reduces field curvature aberrations and assures outstanding optical performance at all focal lengths.
  • The large F4 maximum aperture is consistant over the entire zoom range for faster shutter speeds and flexible the depth of field control.
  • An innovative hybrid AF system offers both extra-smooth, super-quiet SDM autofocus operation using a supersonic motor installed in the lens body, and conventional autofocus operation using a motor built into the camera body.
