Benefits and Features

The optical design of the Irix Firefly lens is impressive and meets the most demanding requirements of modern cameras. With 15 elements in 11 groups, including three high-refractive glass elements and two extra-low dispersion glass elements, this lens offers outstanding image quality. The two aspherical lenses help minimize distortion and aberration while enhancing brightness at the edges of the image.

The new special features that include focus lock, infinity lock, and hyperfocal scale elevate the functionality of manual focus lenses. Thanks to the sophisticated optical design and the special neutrino coating, color aberration, ghosting, and flare have been minimized. The lightweight plastic type used for the housing saves 12% of the weight compared to the Blackstone version.

With a minimum focusing distance of 0.25 meters and nine rounded aperture blades, the lens provides incredibly smooth out-of-focus areas. Its design also allows for the use of 95 mm screw filters in the petal-shaped lens hood as well as a gelatin filter at the back of the lens.
