Additional information:

The Irix 15mm F2.4 is an ultra wide angle prime lens for full frame SLRs and SLMs.

It is coming in two versions: Blackstone and Firefly. Both feature the same optical formula, but the more expensive Blackstone features an aluminum-magnesium alloy construction, metal-grooved focusing ring, and anti-scratch coating. The Firefly trades these things in order to save you weight and cash. It is cheaper and features an anti-slip rubber focusing ring and a lightweight construction that is 12% lighter than its all metal brother.

A focus lock feature in the lens allows the focus ring to be locked in any position, ensuring that your chosen settings for a shot don’t get unintentionally changed.

Other specs and features of the lens include optimization for 50+ megapixel sensors, a special design and coating that reduces aberration/ghosting/flare, 15 elements in 11 groups, a minimum focusing distance of 0.28m (~0.92ft),a 9-blade aperture, and weather sealing against dust and moisture.

The UV light reactive engraved markings on the Blackstone glow in the dark, making this ultra-wide 15mm Blackstone  the better lens for night shooting.
