Irix 15mm f/2.4 is a unique lens, which in the version designed for DSLR cameras has already won the recognition of many professionals and photography enthusiasts. First of all, because of its unique features, excellent workmanship and image quality. Its latest version, designed for Sony mirrorless cameras, is an even more improved design.
The most important feature of the Irix 15mm f/2.4 lens is its focal length of 15 mm. This very short value allows you to record extremely wide frames, which is invaluable in landscape, interior, or architecture photography. This lens provides a wide field of view while maintaining proper perspective. This makes objects in the foreground appear larger and the background appear farther away. This is a great tool for photographers who want to experiment with perspective and create unique shots. What’s more, this lens is also great for Astrophotography, so you can capture beautiful nightscapes.
Another advantage of the Irix 15mm f/2.4 lens is its f/2.4 aperture. This small aperture value allows you to capture images even in low light conditions. The open aperture allows more light to be transmitted, which in turn translates into bright and sharp images in all lighting conditions. It’s ideal for photographers working at night, indoors, or in other challenging lighting conditions.
The design of the Irix 15mm f/2.4 lens is another noteworthy aspect. The whole lens has been designed with the highest image quality in mind. The optics consist of 15 elements arranged in 11 groups, including two aspherical elements and two elements made of low-dispersion glass. This design minimizes optical aberrations such as distortion and vignetting, resulting in high-resolution images with excellent sharpness and color fidelity. In addition, the lens is equipped with modern anti-reflective coatings that effectively reduce flare and flare effects, ensuring even higher image quality.
The Irix 15mm f/2.4 lens is also distinguished by its durability and solidity. It was created for difficult working conditions. It is resistant to dust, moisture, and changing weather conditions – thanks to this, you can successfully use it in any situation without fear of damage.
The “Click / Declick” switch – is a feature now available on Irix photographic lenses for the Sony system. Allows you to choose
between gradual and smooth iris ring operation.
Focus Lock – allows you to lock the focus ring in a specific position, which is extremely beneficial when you want to keep a specific focus plane i.e. in astrophotography, or when using the hyperfocal scale.
95mm front filter thread – allows you to use screw-in filters such as Irix Edge UV & Protector, Irix Edge Circular Polarizer, Irix Edge ND, and Irix Edge Light Pollution filter and others.
Compatible with Irix Edge IFH-100 Filter Holder – allows you to expand your creativity thanks to Gradual Neutral Density filters with different gradients: Soft, Hard and Reverse
The Irix 15mm lens is also characterized by a solid construction (Dragonfly finish version). The body is made of magnesium aluminum alloy combined with a high-quality composite. This ensures durability and resistance to weather conditions with relatively low weight. Dust and moisture resistance mean you can confidently use this lens outdoors, even in harsh atmospheric conditions.
What makes the Irix 15mm f/2.4 lens unique is the possibility of using both classic 95mm screw-on filters, as well as square filters, thanks to the Irix Edge IFH-100 holder!
Every landscape photographer uses filters – they allow a creative approach to photography, which makes them extremely practical. The filters that you can use with the Irix 15mm f/2.4 lens are all 95mm filters, such as the Irix Edge:
UV & Protector – protects your lens against damage
Circular Polarizer – cuts off unwanted reflections and increase the clarity of the photo
Neutral Density – decrease the amount of light reaching the camera sensor, thus allows, for example, creatively to blurs the motion in your photographs.
Light Pollution – cuts off the light of cities, making your night photos full of detail without a yellowish haze
Irix Edge IFH-100 Filter Holder allows you to expand your camera’s capabilities thanks to Gradual Neutral Density filters with different gradients: Soft, Hard and Reverse. By cutting off part of the light from the brightest part of the image, you can shoot even in the most difficult lighting conditions.

"Irix'in sağlam işçilik ve görüntü kalitesine sahip geniş açı lensi 15mm Dragonfly’ı bu videoda detaylı bir şekilde inceledim. F/2.4 diyaframla gelen Irix 15mm, son dönemde kullandığım en kullanışlı geniş açı lens oldu. Peki detaylarında neler yatıyor, gelin hep birlikte bakalım."

"Irix update their classic 15mm lens in a version for Sony E-mount cameras, and with a new aperture ring. How does this older DSLR lens perform on a mirrorless Sony camera?"

"Nowy Irix 15 mm f/2.4 z mocowaniem Sony to dobra propozycja dla miłośników szerokiego kąta, którzy fotografują, filmują lub robią obie te rzeczy na raz. Dość lekka, ale jednak solidna i uszczelniona konstrukcja sprawdzi się nawet w trudnych warunkach. Warto więc zwrócić na niego uwagę, jeśli fotografujemy krajobrazy, kręcimy filmy w plenerze lub działamy hybrydowo. Wtedy też szczególnie docenimy przełącznik pracy pierścienia przysłony, który może poruszać się skokowo lub płynnie."
