With the WonderPana Absolute System you can now use your existing Cokin X-Pro (XL) and/or Lee SW-150 filters with a variety of Ultra Wide Angle lenses using this compatible mounting ring. Due to how this unique mounting ring attaches to the lens, the lens does not need filter threads and will not interfere with the zoom abilities of the lens. Like all products in the WonderPana Line; this is made from Industrial Grade Anodized Aluminum (not plastic) so it will hold up to extreme conditions and abuse for years to come! The filter holder can still rotate freely around the lens front and lock down in place once you find the perfect horizontal placement. Fotodiox has also designed these mounting rings to place the Cokin X-Pro (XL) and/or Lee SW-150 holder closer to the lens, minimizing the space between the filter and lens front which further reduces the amount of light leak and reflection bounce-back. This adapter mount securely and firmly connects the Cokin X-Pro (XL) and/or Lee SW-150 style filter holder to your ultra wide angle lens with no vignetting. You can easily switch from Lee filters to Cokin filters to the Fotodiox WonderPana filter system with just a few quick turns of this competitively priced mount!
