IWhether you are a professional photographer looking for a lens for your next job, or an amateur looking to expand your lens set – the Irix 15mm f/2.4 is a right choice for every landscape photographer!
This is an ultra wide-angle lens created for your full frame (35mm) camera, available in Nikon F, Canon EF, and Pentax K mounts.
This lens will allow you to open up to a new type of photography. Thanks to the 110-degree field of view you will be able to capture eye-catching images, and the excellent optical properties will make the image sharp and full of details.
Creativity, ideas and effort put into a photograph would be nothing without the right lens. Thanks to many years of experience in optical design, our lenses are characterized by their excellent resolution and minimal distortion (2%) and almost no vignetting. The Irix 15mm f/2.4 lens consists of as many as 15 elements arranged in 11 groups: 4 refractive elements, 2 ED elements and 3 aspherical elements. The focusing distance is only 11.02" which, in combination with the f/2.4 aperture and 9 rounded blades, make the lens stand out with an very smooth bokeh with an amazing perspective.
You compose the frame – we will take care of the rest!
Whether you’re traversing the hot sands of the Sahara or the frigid expanse of Antarctica – Irix lenses never back down from any challenge.
The sealing system has been designed to protect the inside of the lens from moisture, dust, and sand. Equally important, the lens does not change its dimensions during focus pulling, eliminating the risk of dirt particles getting swept into the internal structure. These properties not only allow you to work in demanding conditions, but also guarantee the cleanliness of the camera’s mirror chamber sensor.
The Irix 15mm f/2.4 comes in two versions: Firefly and Blackstone.
Firefly – Lightweight composite construction, with an embossed rubber focus ring, allowing for smooth and precise focusing. Included with the lens is a soft pouch.
Blackstone – Reinforced full-metal construction. All lens markings are engraved and filled with a UV-reactive paint enabling easy focusing in dark enviornments. Included with the lens is a hard case.
The Irix 15mm f/2.4 has a module allowing you to control the lens' iris directly from the camera. This means popular semi-automatic modes (PASM), and data recording in EXIF format are available.
The use of electronics also enables the lens to be equipped with a focus confirmation system – the camera will confirm the proper focus distance (either in the form of an icon in the viewfinder or sound), every time you set the focus correctly – it’s really easy!
Irix lenses have correction profiles that are pre-loaded and readable by software (such as Adobe Lightroom and Adobe Photoshop). This will make your shooting experience even more enjoyable.
The Irix 15mm f/2.4 has a small indentation when your focus ring reaches infinity – this enables precise, easy, and quick focusing. You will feel the exact moment when your lens sets to infinity while focusing. This is extremely useful when shooting in difficult lighting conditions (i.e. at night).
The Focus Lock Ring allows you to lock the focus ring in a specific position. This is especially useful when you want to maintain a specific distance to the subject (zone-focusing), or when you want to maintain perfect focus on infinity during landscape or astrophotography.
The rear gel filter slot allows the use of Gray ND filters mounted on the rear of the lens. This is a unique feature of the Irix 15mm f/2.4 and Irix 11mm f/4.0 lenses.
Even though this is a very wide-angle lens, we decided it should be possible to use filters. That's why we designed it with a 95mm front thread. We then created the Irix Edge 95mm filters with their ultra-slim profile to prevent vignetting.
(Of course, you can use any other 95mm filters, as well. Just be aware that they'll need to be low-profile to avoid vignetting, due to the extremely wide angle of this lens.)
Our Irix Filter Holders have also been designed specifically for the Irix 15mm lens, so you can also use our Irix Edge Square Filter system.
Our specially designed, detachable lens hood mounts easily on the front end of the lens, encircling any filter. It detaches with a quick twist and reverse mounts just as easily for storage in the included lens case.
We realized that you'd need to access filters like CPL and variable ND filters to ba able to adjust them. So we included a unique window with a sliding cover to easily reach the edge of those filters while leaving the hood in place to reduce glare.
Due to the specifics of focus detection in DSLR cameras based on phase detection, it may sometimes happen that the lens needs to be synced with the camera. Thanks to this special window, you can easily calibrate the lens at home using basic tools and in just 5 minutes. Fast, simple and effective!
