Pentax HD PENTAX D FA* 70-200mm f/2.8 ED DC AW Lens

The HD PENTAX D FA* 70-200mm f/2.8 ED DC AW Lens combines a flexible zoom range with a rapid, constant f/2.8 maximum aperture, making it an ideal telephoto zoom for Pentax K-mount DSLRs. When used with APS-C cameras, it provides a focal length equivalent to 105-300mm, rendering it particularly effective for sports, landscape, and wildlife photography, especially in challenging lighting conditions. The optical design incorporates extra-low dispersion glass elements to significantly reduce chromatic aberrations and distortions, ensuring exceptional sharpness across the entire frame. Additionally, HD and Aero Bright coatings are applied to the lens elements to minimize reflections and flare, while a Super Protect coating offers protection against dust, water, and oils on both the front and rear elements. To further enhance its usability in adverse conditions, this 70-200mm f/2.8 lens features a weather-resistant design with 13 seals to prevent moisture and dust ingress.

Regarding its focusing capabilities, the lens is equipped with a DC autofocus motor that delivers swift and silent operation, complemented by the Quick-Shift Focus System, which allows for seamless transitions between autofocus and manual focus by simply rotating the focusing ring. Furthermore, a detachable, rotating tripod collar is included to provide improved balance when mounted on a tripod.

• One of the most versatile zoom ranges, this 70-200mm lens provides a 105-300mm equivalent focal length range when used with Pentax APS-C DSLRs.
  
  
• A constant f/2.8 maximum aperture delivers consistent performance throughout the zoom range and is particularly beneficial to creating shallow depth of field imagery.
  
  
• Extra-low dispersion glass elements are incorporated within the optical design to minimize chromatic aberrations throughout the zoom range and produce high image clarity with edge-to-edge sharpness.
  
  
• High Definition (HD) and Aero Bright coatings have been applied to lens elements to reduce surface reflections, flare, and ghosting in order to deliver greater contrast and color fidelity. Additionally, a Super Protect (SP) coating also helps to protect the surface of exposed elements from fingerprints, water, dust, and oils and also makes the front and rear elements easier to clean.
  
  
• A Direct Current (DC) autofocus motor benefits from an internal focusing design and delivers fast, smooth, and quiet focusing performance.
  
  
• The Quick-Shift Focus System allows you to first use autofocus to acquire general focus on a subject, then instantly refine your focus position manually without the need for an AF/MF selector.
  
  
• A focus range limiter allows you to constrain the lens' focus range between different sets of distances for faster performance and greater responsiveness.
  
  
• The weather-resistant construction utilizes 13 distinct seals to prevent moisture or dust from entering the lens.
  
  
• A removable, rotating tripod collar is included with the lens for better balance when shooting atop a tripod.
