High performance lenses - More than meets the eye!

IRIX 15mm f:2.4 Blackstone:

The ultra wide-angle, rectilinear manual focus lens designed for DSLR cameras. Providing a focal length of 15mm, this lens is ideal for outdoor and indoor photography. The new special features such as focus lock, infinity click and hyperfocal scale set a new level of manual focus lens functionality. Thanks to sophisticated optical construction and special neutrino coating, colour aberration, ghosting and flare effects have been reduced to the absolute minimum. With a minimum focusing distance of 0.28 metre (0.92 ft) and 9 rounded shaped aperture blades, the lens stands for supremely smooth out-of-focus areas. The design of the lens allows the use of 95 mm screw-in filters at the front in the petal-shape lens hood and gelatin filters at the back of the lens.

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 four 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.

Not only does the IRIX 15mm f:2.4 lens perform extremely well for Astrophotography and any other type of photography it also performs very well in the Infrared and Full Spectrum world. With no Hot-Spots and the ability to attach screw on filters (95mm thread size) this lens is a wonderful compliment for any type of imaging.

IRIX 150mm f:2.8 Dragonfly:

Modern and versatile macro telephoto lens designed for full-frame high-resolution DSLR cameras. Its large aperture of f/2.8 facilitates shorter exposure times, while its moderately long focal length of 150mm provides an excellent compromise between the narrow viewing angle desired in advertising and portrait photography, and the convenience of hand-held photography. The unique feature of the Irix 150mm f/2.8 lens is the 1:1 Macro reproduction ratio already available at a focusing distance of 0,345m.

The lens is equipped with an aperture mechanism consisting of 11 aperture blades with a rounded shape which provides a pleasant blur of background and points of light. High precision of focusing across the entire range is ensured by a wide, rubber-coated focus ring with a rotational angle of 270°. An additional Focus Lock ring ensures that the focus position remains fixed when needed.

The Irix 150mm f/2.8 Macro 1:1 is the first lens available in the new Dragonfly series, which combines the lightness and perfect ergonomics of the Firefly and the durable magnesium housing used in the Blackstone. Key features of the Dragonfly version.

A great way to improve your nightscape photography is by using an IRIX lens. A precise manual focus ring provides very fine focus and a built-in focus locking ring helps keep everything sharp even when moving your camera between compositions.
