Product Description

The Irix 15mm f/2.4 Firefly Wide Angle Lens (PENTAX) is designed to deliver the best optical performance and match the demands of full frame DSLR cameras. Providing a focal length of 15mm, this new lens model is ideal for outdoor and indoor photography whether it is photojournalism, landscapes or architecture. The new special features such as focus lock, infinity click! and focus scale calibration set a new level of manual focus lens functionality. Thanks to sophisticated optical construction and special neutrino coating formula, 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 and gelatin filters at the back of the lens.

Firefly is the standard version equipped with three 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.

The Irix lenses are in two varieties: 'Blackstone' and 'Firefly.' The Irix Blackstone features a magnesium and aluminium body able to withstand 'extreme conditions,' while the Irix Firefly models are lighter, made from lightweight durable plastic. and offer approximately 12% weight saving.

This is the Firefly version, the same optical performance and high quality mechanism as the Blackstone, but implemented in a lightweight design. The ergonomic focusing ring offers the freedom to capture the most ideal moment, whether it is big city architecture or wildlife scenery.
