Lens Description

The Irix Blackstone 15mm F/2.4 is an ultra-wide prime designed for cameras with Full-Frame sensors. This bright prime has a 15mm focal-length. The body of this lens is weatherproof against adverse weather such as rain and snow. It has sealing to prevent entry of water and dust.

This prime is capable of focusing down to 25cm from the imaging plane which gives it a maximum magnification of 0.11X. The lens is not capable of autofocus and so the focus-distance must always be manually adjusted via the focus-ring.
