Designed for up to 8K cine-style image capture and covering up to full-frame size sensors, the PL-mount 11mm T4.3 Cine Lens from IRIX incorporates multiple internal and external design features. This 11mm lens will produce a classic wide-angle look or up to a 123° viewing angle in the 2.39:1 widescreen format, depending on your camera's sensor. External features include a 95mm front diameter, 0.8 MOD gears, luminous focus marks in feet, and a detachable 1/4"-20 support foot.

Internally, nine blades produce smooth, rounded bokeh and four seals protect against inclement weather and dust. To help eliminate aberrations and distortion, the IRIX 11mm T4.3 Cine Lens is constructed with 16 optical elements in 10 groups, including four HR (high refractive index) and two ED (extra-low dispersion) elements. A Multi-Start Thread focusing mechanism delivers quiet, precise focusing even in wet or humid conditions or in extreme temperatures. This lens has 180° of focus and 75° of iris rotation, an 86mm front filter thread, and includes front and rear caps.

Q: 8. Can anyone tell me how to read/use the hyperfocal scale on this lens? I know what hyperfocal focus is and on most other lenses I know how to use it, but the scale on this lens is truly perplexing to me - specifically, why are there multiple aperture values on both the left and right sides of the centre mark? And there's also another hyperfocal marker above the distances as you approach the infinity mark. So far I've only been able to test it visually by taking the same photo at different focus values and comparing them on my computer to see which are the most in-focus. This is by no means a very technical approach to achieving the proper focus, so I'm very interested in learning how to properly use the hyperfocal scale on this lens. Thanks in advance for any information anyone can provide!

A: The aperture scales on the left and right of the focus mark indicate the approximate distances from the focal plane of the camera within which the image will be acceptable sharp at the current focus setting. It's referred to as a depth of field scale. The hyperfocal scale allows you to set your focus to the approximate hyperfocal distance for your current aperture, by aligning the f/number on the scale with the center focus mark. Irix has a good article on their site explaining DoF, hyperfocal distance and how to use both scales.
