The 11mm f/4 Blackstone lens from Irix is an ultra-wide-angle lens designed for Nikon F-mount DSLRs. As a rectilinear lens, the advanced optical design includes aspherical, ultra-low dispersion, and high refractive index elements to control distortions and aberrations, offering accurate and clear performance with high color accuracy.

The lens features a...

  • Type

    Wide Angle

    Wide-angle lenses with optics that allow for fitting many elements within the frame with relatively little distortion. Their focal distance is usually 24-35mm for full-frame, 15-25mm for crop frame, and 50-70mm for medium format. They are commonly used in street photography but also in indoor spaces where there is limited distance from the subject. The perspective of wide-angle lenses makes things appear farther apart than they actually are.

  • Mount

    The type of mount that the camera body must have in order for the lens to be fully functional when attached to it.

    2. Some lenses can be used with older mounts from the same manufacturer, sacrificing certain functions (e.g. autofocus), or even with mounts from other manufacturers using an adapter.

  • Item

    Lenses with variable optical (zoom) that remain equally bright (same maximum aperture value) throughout the entire focal distance range they offer. Usually significantly more expensive than their variable aperture counterparts.

    Fixed Focal Length

    Lenses with fixed optics are usually of higher quality than a corresponding zoom lens at the same focal distance. They are also called "fixed" or "prime" lenses.

  • Sensor Type

    Full Frame

    Photographic lenses designed for use on full frame sensor cameras. A full frame lens can also be used on a crop frame sensor camera, but with its focal length adjusted according to the corresponding crop factor.

    For example, a full frame lens with a focal length of 50mm (standard) on a camera body with a crop factor of 1.6 will function with a perspective as if it were an 80mm lens (telephoto).

    The reverse does not work as the optics of a crop frame lens are not sufficient to cover an entire full frame sensor, resulting in the edges of the frame being black (severe vignetting).

  • Maximum Aperture (f)

    Opening the diaphragm determines the amount of light received by the camera and affects the depth of field.
    2. The most open aperture of a lens is called the maximum. The more open the aperture (smaller f-number), the shallower the depth of field.

Description

Description

The 11mm f/4 Blackstone lens from Irix is an ultra-wide-angle lens designed for Nikon F-mount DSLRs. As a rectilinear lens, the advanced optical design includes aspherical, ultra-low dispersion, and high refractive index elements to control distortions and aberrations, offering accurate and clear performance with high color accuracy.

The lens features a manual focus design for better control and includes a unique positive focus lock mechanism, which secures the focus position at any point for consistent and repeatable shooting. The Blackstone version of this focal length is characterized by an aluminum-magnesium exterior construction, engraved lens markings with UV fluorescent paint for high visibility, and extensive weather sealing.

  • Durable aluminum and magnesium construction.
  • Dust and moisture resistance with internal seals and an additional seal on the front element.
  • Scratch-resistant surface.
  • Focus and depth of field markings with UV fluorescent paint.
  • Designed for FX-format cameras and can also be used with DX models.
  • Three aspherical, four high refractive index, and two ultra-low dispersion elements within the optical design.
  • Neutrino coating to limit flare.
  • Positive lock mechanism to maintain focus position.
  • Hard click indicator for the infinity position.
  • Built-in petal-shaped lens hood to reduce reflective brightness and protect the front element.
  • Accepts 30 x 30mm gel filters.
  • Nine-blade rounded diaphragm for smooth bokeh.

It is the distance that the light rays need to travel to reach the focal point, that is, the lens sensor.
The smaller the focal distance, the larger the angle of view for the photograph and therefore the lens can capture more of what is in front of us.
