The Holder for Laowa 12mm f / 2.8 allows you to simultaneously use up to two square filters and a circular polariser (included) with minimal vignetting up to a rotation of about 45 °. A very slight vignetting is present at 12mm on full-frame with polariser (absent when the polarizer is not mounted.) The polariser has been included for completeness but is to be used with care given the extreme focal length on full-frame. An exceptional result with 100mm filters and with a focal length of only 12mm on full-frame, this is a result much higher than the other holders on the market for this lens. The holder is CNC machined from a single block of aeronautical aluminum and it is coated with a matte black protective paint to minimize unwanted reflections.
