Irix 11mm f/4 Firefly Lens for Canon EF

This extremely wide-angle, rectilinear manual focus lens designed for DSLR cameras, and is an extremely wide Full Frame rectilinear lens with a 126° angle of view. 4 high refractive lenses, 2 ED lenses and 3 aspherical lenses guarantee minimal distortion, as low as 3.13%, making our 11mm f/4.0 lens absolutely unique in its class.

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.

Firefly is the standard version equipped with three rubber seals that protect camera mount and focusing mechanism against dust, moisture and side accidental water splashes. Ergonomic focusing ring with rubber grip offers the freedom to operate with the camera. It is the most lightweight lens in its class.

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.
