Filters
Remember, you need filters that don’t degrade the image coming through the glass in your expensive lenses. So,over the last few years, I have upgraded to B+W and Singh-Ray for screw on filters. My two Nikon filters are specialty filters made only by Nikon for the 600mm and 180-400mm lenses. I purchased the Lee filter 150mm system for my Nikon 14-24mm lens. It was the only available option. Now I use the Lee 150mm filter system for several of my lenses. The Zeiss 15mm focal length lens has a 95mm filter thread. I bought the Lee 150X150 Mrk II Lens Adapter for the various filter sizes I need and they seem to work great. Vignetting with the Zeiss 15mm and 25mm lenses has not been a problem using the 150mm filters. These Lee filters do create a color cast, but that gets corrected in post processing. So far, the Lee filters with no color cast are insanely expensive. I carry the circular filters in a Mindshift filter nest. I carry the Lee filters in a Lee carrying case.
