  • 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 Irix Firefly camera lens is a wide-angle prime lens designed for full-frame cameras. It features an optical construction of 16 elements in 10 groups, including four refractive elements, two ED elements and three aspherical elements, for reduced distortion of 2%. Its 110° angle of view and f/2.4 aperture make it suitable for landscape and night-sky photography.

The Firefly version has a lightweight composite construction and a textured rubber focus ring. The infinity click feature makes precise focusing easier, while the focus lock keeps the ring in the selected position. The sealing system protects the inside of the lens from moisture, dust and sand, and focusing does not change its dimensions.

Ultra-Wide 110° Field of View and Low 2% Distortion

The lens offers an impressive 110-degree angle of view on Full Frame sensors.
It lets you capture expansive scenes in a single, dynamic frame.
It stands out for its exceptionally low geometric distortion of just 2%.
It ensures straight lines look natural in architecture and landscapes.
It delivers uniform image quality from corner to corner without noticeable vignetting.
It offers a unique perspective with crystal-clear detail for professional and artistic photography.

Bright f/2.4 Aperture and Astrophotography Capabilities

The fast maximum aperture of f/2.4 ensures superior light collection at the sensor.
It is an indispensable tool for astrophotography and night photography.
It captures the night sky and the Milky Way impressively at low ISO.
The optical aperture consists of 9 rounded blades for a smooth, circular opening.
Combined with the minimum focusing distance of 28 cm, it produces exceptionally smooth bokeh.
The aperture can be stopped down to f/22, offering full exposure flexibility during the day.

Optical Design with ED Elements, Aspherical Elements, and Neutrino Coating

The optical construction comprises 16 elements arranged in 10 groups.
It incorporates three aspherical elements and two ED (Extra-Low Dispersion) elements.
It also includes high-refractive-index (HR) elements to reduce bulk.
This configuration effectively eliminates spherical and chromatic aberrations.
The glass elements feature the special multilayer Neutrino Coating.
It dramatically suppresses flare and ghosting, delivering high contrast.

Innovative Infinity Click and Focus Lock Mechanisms

Features the innovative Infinity Click function, with a tactile detent at the infinity mark.
Enables photographers to find infinity focus instantly, even in complete darkness.
Incorporates a unique Focus Lock mechanism to secure the ring at any position.
Prevents accidental changes to the focus distance during long exposures.
Electronic contacts enable aperture control from the camera, as well as PASM and EXIF functions.
Supports audible and visual focus confirmation in the viewfinder for complete confidence.

Lightweight Firefly Construction, Weather Sealing, and Dual Filter System

The Firefly version features a lightweight body made of ABS composite material and a rubberized ring.
The body is sealed against moisture, dust, and sand, with no change in length during focusing.
The front features a standard 95 mm filter thread for screw-in filters.
The rear incorporates a 30 x 30 mm rear gel filter slot to prevent vignetting.
It is fully compatible with the Irix Edge IFH-100 holder for using square filters.
The lens hood features a sliding window for adjusting a polarizing filter for convenient operation.

Focal Length

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.

    Excellent ultra-wide-angle lens.. amazing colors, minimal distortion, minimal vignetting.. it is fully manual so don't expect autofocus.. I don't need it so it doesn't matter to me.. it has a nice click at infinity and it is at infinity.. it has a hyperfocal scale and focus lock.. minus one star because it has a huge diameter (95mm) which makes filters prohibitive.. but it can take gelatin ND filters on the back.. Nice feature for me. It's worth its money, especially for astrophotography where it is amazing.. right after that, of course, there is the Sigma which is in a different league.
