is there really no way to add ND filter systems to this lens? No compatible products? I love this lens for astrophotography and sunsets but need to add light pollution or reverse gnd filters to enhance those subjects.
Asked by: Emma
One could try to connect the NiSi 150mm Filter Holder for Voigtlander Hyper-Wide Heliar 10mm Lens: https://bhpho.to/2yUDy6z . The Focal Length of both lenses is the same, and the adapter mounts behind the lens shade of the lens, and is made not to vignette mounted on a 10mm lens. But the two shades look different, The Rokinon lens shade is longer, so attaching may not work. If one could shorten the depth of the lens shade it may fit, otherwise it may not be possible to mount filters on the Rokinon 10mm f/2.8 ED AS NCS CS Lens for Pentax K Mount

Any one noticed that is only 2/3 brighter than the canon 10-18 f4.5, instead of 1-1/3rd stop?
Asked by: Carlos
We are not aware of any side by side comparison testing with this and the Canon 10-18mm F/4.5-5.6 lens. However, aperture ratings on photography cameras like this are not uniform across the board.
