The 2 to 5-stop Edge MMS Magnetic Variable ND Filter for IRIX Cine Lenses from IRIX darkens the entire image area by increasing density by 2 to 5-stops, providing finer control over exposure, depth of field, and frame rate. It provides excellent contrast and sharpness due to its optical glass construction and multilayer, antireflective coatings. The dirt-repellent nano coatings and Super Resistant (SR) optical glass offer easy cleaning and high resistance to mechanical damage, making it ideal for use in harsh locations. A no-slip finish on the bottom ensures the filter will stay in one place while being attached by only magnets. This filter's slim design resists vignetting when used with wide-angle lenses and allows stacking with other magnetic filters.

Q: 1. What changes and how does the " An adaptive focus ring" adapt from manual to follow focus use?

A: On the IRIX 15mm T2.6 Cine Lens, the focus ring does not change, but rather, it is conducive to both manual use (by hand) and for use with a follow focus (motorized or manual), due to it's ergonomic design, equipped with 0.8 pitch gear teeth.

Q: 2. Would this 11mm be equivalent to a 24mm on Super35 sensor, specifically the Blackmagic 6K Pro?

A: Used on the Blackmagic Design Pocket Cinema Camera 6K Pro (Canon EF) (B&H# BL6KPKCAMP) with its 1.6X crop-sized APS-C sensor, the IRIX 15mm T2.6 Cine Lens (Canon EF, Feet) (B&H# IRC15EFI) will render a field of view that is equivalent in its effective focal length to using a 24mm lens on a full frame sensor-equipped camera body. If you instead opt to use the IRIX 11mm T4.3 Cine Lens (Canon EF, Feet) (B&H# IRC11EFI) with that same camera then the field of view in terms of its its effective focal length would be equivalent to using an 18mm lens on a full frame sensor-equipped camera body.

Q: 3. Is this wide angle cine lens a Rectilinear lens or a Fish Eye lens? Mount Nikon Z, Focus Scale Metric, 11mm

A: The IRIX 11mm T4.3 Cine Lens (Z-Mount, Meters) is an Ultra-wide angle lens.

Q: 4. what is the solution to add an Uv protection filter on this lens?

Q: 5. Is it possible to use the IRIX matte box with the IRIX PHOTO lenses to use the magnetic mount system filters?

A: Yes the IRIX Cine Matte box is designed to work with in the IRIX magnetic filter ecosystem. You can use the Irix MMS Magnetic Filters on any lens with the Irix Matte Box IQ and available adapters. That is why IRIX created the Irix Matte Box IQ. To let you attach and remove filters as quickly as possible. With the Irix Matte Box IQ, the Magnetic Mount (MMS) has been moved from the lens to the Matte Box, so you can enjoy all the benefits of Irix filters, no matter which lens is your favorite.

Q: 6. What benefits, if any, would there be if I purchased the canon mount and used it on a Fuji XH2S with the metabones speedbooster?

A: The Metabones Canon EF lens to Fuji X-mount adapter would preserve the wide angle of the IRIX 30mm T1.5 Cine Lens as well as boost low light performance by 1 stop when used on crop sensor cameras like the Fuji XH2S. When using the IRIX 30mm lens without a speedbooster the lens would provide a 45mm view. When using the speedbooster the view would be 32mm.

Q: 7. In a BMPCC 6K Pro camera, this 11mm equals to what mm?

A: The IRIX 11mm Lens on the BMPCC 6K Pro will become roughly a 16.5mm lens.

Q: 8. Regarding PL mount. Do these fit high end pl cameras? I have found they don't..

A: Yes, the IRIX 30mm T1.5 Cine Lens - PL Mount (BH #IRC30PLI) should fit on any PL mount camera. Please reach out if you have compatibility issues.

Q: 9. Would I be able to put a clip on mattbox on this lens to use a polarizer or would that vignette?

A: The diameter of the front of the IRIX 11mm T4.3 Cine Lens (Canon EF, Feet) (B&H# IRC11EFI) -- not to be confused with the filter size -- is 95mm which is a very common size to which to attach a matte box. Yes, it would be possible to do so. Given the ultra wide nature of the field of view, however, there will of course be at least some amount of vignetting regardless of the size of the filter, but that is unavoidable.

Q: 10. Does this e-mount version on this lense take advantage of Sony Autofocus, say in the FX6

A: This is a manual focus lens. There is no auto focus functions that will work on this lens.
