The optical construction of the Irix Firefly wide-angle lens is superb, meeting the most demanding requirements of modern cameras. 15 elements in 11 groups include three elements of highly refractive glass and two of extra-low dispersion glass. Two aspherical lenses provide extremely high image quality and improve image brightness at the edges, while minimizing distortion and aberration.
Additional Feature
- 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.
- Click at infinity - enables precise, easy, and quick focusing. During focusing, you will feel the exact moment when your lens sets to infinity, which is extremely useful when shooting in difficult lighting conditions (i.e. at night).
- Rear Gel filter slot– allows the use of Neutral Grey filters mounted on the rear of the lens, which is a unique feature of the Irix 15mm f/2.4 and Irix 11mm f/4.0 lenses.
- 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.
- Circular Polariser Adjustment Window– the lens hood is equipped with a sliding window, allowing you to freely rotate the polarizing filter without the risk of getting dirty.
- 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.
- Focus Calibration window – due to the specifics of focus detection in DSLR cameras based on phase detection, it may sometimes happen that the lens needs to sync with the camera. Thanks to this special opening, you can easily calibrate the lens at home using basic tools within 5 minutes. Fast, simple and effective!
Firefly is the standard version equipped with three rubber seals that protect camera mount and focusing mechanism against dust, moisture and accidental water splashes. Ergonomic focusing ring with rubber grip allows to have more freedom when operating the camera. It is the most lightweight lens in its class.
Makes for a lightweight journeyThe same optical performance and high quality mechanism as the Blackstone, but implemented in a lightweight and handy design. Whether you sail, hike, drive or fly, the Irix Firefly 15mm f/2.4 will make your journey extraordinary. The ergonomic focusing ring offers the freedom to capture the most ideal moment, whether it is big city architecture or wildlife scenery. Challenge accepted.
Intelligent Lens DesignThe Irix 15mm f/2.4 lens has a module that allows you to control the lens’ iris directly from the camera, thanks to which popular semi-automatic modes (PASM) and data recording in EXIF format are available. The use of electronics also enable the lens to be equipped with a focus confirmation system – the camera will announce the correct focus setting (either in the form of an icon in the viewfinder or with a sound), every time you set the focus correctly – it’s easy and convenient!
It’s worth noting that Irix lenses have the appropriate correction profiles that are pre-loaded and readable by software (such as Adobe Lightroom and Adobe Photoshop), that will make your shooting experience even more enjoyable.

"I was incredibly surprised at the quality of the Irix and can easily say it is an excellent lens. Both of the “Firefly” and “Blackstone” versions are optically and mechanically sound. Their sharpness is fantastic, with distortion and vignetting very well controlled. There are no problems with chromatic aberration, and ghosting and flare are are kept in check. I really hope that TH-Swiss produce more lenses like this in future. The Irix 15mm f2.4 is produced for Canon EF, Nikon F and Pentax K mount." Read full review |
"I think a purchase here will really depend on what your intended uses of the lens will be. Since you don't have the option for autofocus, it may be trickier for an events photographer, particularly if you're planning on shooting at wider apertures for such events. But if you're a landscape photographer, particularly if you shoot a lot of night skies or in low light conditions, then this would be a great lens for you. I'm telling you, the lock focus ring makes night shoots so incredibly smooth." Read full review |
"While reviewing this lens, I was not being overwhelmingly convinced of its value proposition. But, when I started putting the Irix 15mm f/2.4 Blackstone Lens up against the comparables, I began to see it in a different light. It is not a perfect lens, and I would especially like to see the wide open corner image quality improved. But for the price, its value is easy to recognize. Getting a weather-sealed aluminum-magnesium lens barrel with decent image quality for a relatively low price puts this lens squarely on the consideration list. And for a new lens manufacturer, that is an impressive feat." Read full review |
"The Irix 15mm combines impressive handling and build quality with superb image quality, at a bargain price. The only flaw in our review sample was the lack of exposure consistency." Read full review |
"The Irix 15mm f/2.4 lens is a powerful photographic tool. This new lens from Irix lifts the performance for such lenses way beyond the first early 1970s offerings and gives us a lens that is free from flare, and very sharp. This Swiss design is an excellent one, built in Korea to very high standards." Read full review |
"The Irix 15mm f/2.4 is an excellent super-wide-angle prime lens that delivers very good image quality. Sharpness in the centre of the frame is excellent throughout the aperture range, even wide open at f/2.4, with f/4-f/11 producing the best results. The edges of the frame aren't quite as sharp, but still very good." Read full review |
"The build quality of the Firefly model of the lens is solid and robust. I don’t work that often in bad weather, so the extra weather sealing of the front element of the Blackstone is not quite so important. The Blackstone model is an all metal construction, so if you mistreat your kit, a bit more forgiving." Read full review |
"I was extremely convinced with the lens, it is not a perfect lens, but when we talk about ultra wide lens, the perfection is almost impossible. If you’re looking for an ultra-wide angle rectilinear prime for landscapes, architectural and travel photography, the Irix 15mm f/2.4 Blackstone is an excellent value." Read full review |
"Yes, there is lens(es) with better image quality but with triple price. I can easily say that Irix Firefly offers very good image quality in its price-range (approx. 450€ in Finland) and adding those new features like “Focus lock” and “Infinity click” makes it a solid performer. Highly recommended." Read full review |
"Here we have the first lens by Swiss designers Irix (who manufacture in South Korea): a 15mm f/2.4 lens for full-frame cameras. It's manual-focus only, but seems to be reasonably good value for money, especially considering its very wide aperture of f/2.4. Let's see how it performs." Read full review |
"Seriously, it’s like operating a point-and-shoot! There’s no messing about doing differential focus, just turn the focus ring until you feel the ‘click’ and take the shot – simple." Read full review |
"It’s taken me a while to get an Irix lens in my hand, but I have to say I’m pretty impressed for this new company’s first “kick at the can”. The Irix 15mm f/2.4 (particularly in this Blackstone finish) comes across as a pretty mature offering" Read full review |
