150mm Filter Holder
For use with Sigma 12-24mm f/4 HSM Art Series lens (No vignetting at 90 degrees rotation)
This NiSi 150mm Filter Holder is specially designed to be used with the Sigma 12-24mm f/4 HSM Art Series lens. Made from aviation-grade aluminium with single element processing by CNC machine, it supports up to two 150mm filters at the same time.
Using a square and rectangular filter system instead of standard round screw-on filters will allow you to use the same filters with many different sized lenses. Simply change your filter holder's adapter ring to suit your lens. It will also allow you to shift your filter up and down in the filter holder to fit the scene you are photographing, making it easier to match your filter to your horizon line or balance the light intensity in both parts of a scene.
This 150mm Filter Holder consists of a lens mount clamp foundation for the Sigma 12-24mm f/4 HSM Art Series lens and filter installation system. The ergonomic design makes it easy to mount on your lens, and once mounted it can be rotated 360 degrees. It features a matte black frosted finish on the surface to minimise reflection.
Please note that with this filter holder there is no vignetting at 90 degrees rotation. However there will be some vignetting when rotated to other degrees. To achieve no vignetting you will need to instead use the NiSi Sigma 12-24mm f/4 HSM ART Series Adapter for NiSi 180mm Filter Holder.
