## Long description

The Irix Firefly 11mm f/4.0 is an ultra-wide rectilinear lens for SLR cameras with a 126° angle of view. Constructed from 16 elements in 10 groups and finished in a compact, lightweight metal body, this 11mm f/4 lens delivers high image quality with minimal distortion while remaining easy to carry. The lens is compatible with Canon EF mount and features a 30mm filter size, making it suitable for landscape and architectural photography.
Advantages
This 11mm f/4.0 lens combines an extremely wide field of view with low distortion thanks to a design that includes 4 high-refractive elements, 2 ED elements and 3 aspherical elements; measured distortion can be as low as 3.13%. The Firefly model preserves the optical performance and precision mechanism of larger models while offering a notably lighter construction (approx. 0.73 kg). Its solid aluminium and magnesium body provides robust protection, while engraved fluorescent markings and a rubber-coated, anti-slip focus ring ensure practical, user-friendly handling in varied lighting and weather conditions. Weather sealing and inner seals protect the lens from dust, moisture and accidental splashes.

How to use
Mount the Irix Firefly 11mm f/4.0 on a compatible Canon EF SLR body and set the camera to the desired exposure settings. Use the engraved fluorescent markings for easy focusing in low light and turn the rubber-coated focus ring for manual focus adjustments. For landscape and architecture, stop down the aperture toward f/8–f/16 to increase depth of field and achieve sharpness across the frame. When shooting handheld, compensate for the wide angle by using steady handling or a tripod for maximum sharpness.
Usage recommendations
For best results in landscape and architectural work, use the lens on a full-frame Canon body, choose smaller apertures for greater depth of field, and protect the front element with appropriate filters. The lightweight Firefly construction is recommended for travel and hiking, while the weather sealing provides added protection in variable conditions.
