We know how important it is to protect your gear. All Irix lenses are made with phenomenal precision. Each Irix lens is equipped with a weather sealed construction which protects the interior against dust and moisture. Thanks to inner seals, our lenses are also protected from accidental water splashes. No matter the journey, you can be confident that our weather sealed lenses will offer you maximum resistance to the extremes.

Blackstone, the Premium version has durable body made with aluminium-magnesium alloy, that ensures foolproof protection of your lens, even in extreme situations. Its construction is equipped with rubber seals, that protect the camera mount and focusing mechanism against the dust and moisture, as well as front or side accidental water splashes. Engraved fluorescent markings enable easy read-out and operation in low light conditions.

Additional Features

  • Infinity click – Enables quick, easy, and precise focusing. During focusing, you’ll feel the moment when your lens hits infinity, which is extremely useful when shooting in difficult lighting conditions (I.e. at night).
  • Focus Lock – Allows you to lock the focusing ring in a specific position, which is extremely beneficial when you want to keep a specific focus plane, i.e. for astrophotography, or when using the hyperfocal scale.
  • Focus Calibration Window – due to the specifics of focus detection in DSLR cameras (which are based on phase detection), sometimes it may happen that the lens needs synchronization with the camera. Thanks to this special window you can easily calibrate the lens at home using basic tools within 5 minutes. Fast, simple and effective!
  • Rear Gel Filter Slot – Allows the use of neutral gray filters, (a unique feature of the Irix 11mm f/4.0), against the background of competing ultra-wide-angle builds that do not have the option of using filters.

"The Irix 11mm f/4 is an excellent ultra-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/4, as are the edges, with f/5.6-f/11 producing the best results. The Irix 11mm f/4 is a pleasure to use, thanks to its superb build quality, smooth focus ring and hyperfocal scale." Read full review

"What an exciting lens the Irix 11mm f/4 Firefly is. It opens up a whole new world of creative possibilities in a well-made, well-designed package that delivers the image quality. It will not be for everybody, perhaps because of the ultra-wide style of the images, or maybe because of difficulties using the manual focus system, but if the lens appeals to the individual photographer's creativity then it will be a rewarding experience." Read full review

"The Irix 11mm f/4 Blackstone is a well made and competitively priced ultrawide lens for full-frame Canon, Nikon and Pentax DSLRs. Image quality and handling are very good, but if our test sample lens is anything to go by, you may have to make some exposure corrections to compensate for the lens's imprecise aperture diaphragm control."

"In terms of image quality, I was pleasantly surprised by the optical performance of this glass. The sharpness in the center is very good even at the widest settings, while the corner resolution improves significantly at f/5.6. Have a little bit of Vignetting and chromatic aberration at f/4 but they also decrease when stopping down the aperture." Read full review
