Product information

Description

The Irix Blackstone 11mm f/4.0 is an ultra-wide Full Frame rectilinear lens offering a 126° angle of view and a lens construction of 16 elements in 10 groups. Designed for Pentax K mount cameras, it provides a closest focusing distance of 0.275 m and a robust aluminium-magnesium body in black. This lens combines very low distortion (around 3.13%) with a lightweight build and engraved fluorescent markings for easy operation in varied lighting conditions.

Advantages

The lens delivers minimal distortion through the use of 4 high refractive elements, 2 ED elements and 3 aspherical elements, while maintaining a compact, lightweight construction that does not compromise optical performance. Weather-sealed construction and durable materials ensure reliable protection against dust, moisture and accidental splashes. An ergonomic, rubber-coated focus ring with anti-slip surface improves handling for on-the-go photography.

Suitable for

  • Landscape and architecture photography requiring minimal perspective distortion
  • Travel and hiking where low weight and compact size are important
  • Interior and real-estate photography in tight spaces
  • Astrophotography and nightscapes where a very wide field of view is needed

Key specifications

  • Focal length: 11 mm (ultra-wide)
  • Maximum aperture: f/4
  • Minimum aperture: f/22
  • Optical construction: 16 elements in 10 groups
  • Closest focusing distance: 0.275 m
  • Angle of view: 126° (Full Frame)
  • Mount: Pentax K
  • Body material: aluminium and magnesium
  • Colour: Black

How to use

Attach the lens to a Pentax K mount camera following the camera manufacturer’s instructions. Use the engraved fluorescent markings to set focus and align settings in low light. For landscapes and architecture, set a smaller aperture (higher f-number) to increase depth of field; for night or low-light scenes, use the maximum aperture of f/4 and adjust ISO and shutter speed accordingly. The ergonomic rubber-coated focus ring allows manual focusing when required.

Usage recommendations

To preserve optical performance and weather sealing, keep front and rear elements clean and avoid prolonged exposure to heavy rain. Use a lens hood or protective filter to reduce stray light and protect the front element when shooting in challenging conditions.
