Fotodiox WonderPana 66 FreeArc Essentials CPL & GND 0.9 Hard Edge Filter Kit for Sigma 14-24mm f/2.8 DG DN Art Lens

Under the umbrella of advanced photography equipment, the WonderPana 66 FreeArc Essentials CPL & GND 0.9 Hard Edge Filter Kit for Sigma 14-24mm f/2.8 DG DN Art Lens stands out as a versatile and high-quality addition to any photographer's toolkit. Specifically designed for the Sigma 14-24mm f/2.8 DG DN Art Lens, this kit enhances the lens's performance by providing a perfect fit and optimal functionality.

The kit includes a robust filter holder and a 6.6" bracket from Fotodiox, dedicated to attaching 145mm threaded filters and caps to the lens. The lens itself lacks filter threads, but with the included bracket, you can work with 6.6"-wide square and rectangular filters. Once assembled, the entire system offers a full 360-degree rotation, providing flexible placement of the filter in use.

The Fotodiox WonderPana 6.6" Holder Bracket is a two-piece assembly designed to be used in combination with a Fotodiox WonderPana FreeArc Core Unit. This allows for the convenient use of two 2.5 to 4.0mm-thick filters measuring 6.6in wide, or one 6.6in wide filter along with one 145mm round filter behind it. The WonderPana 6.6" Holder Bracket features a lightweight, aluminum-alloy construction that has a corrosion-resistant, black anodized finish for durability. A rigid pouch is included for storage and transport.

The kit also includes a 145mm Multi-Coated CPL Filter - Fotodiox Pro 145mm Slim MC-CPL Filter. This double threaded, multi-coated circular polarizer (MC-CPL) filter is made of optical glass and features a rotating ring to allow for light ray selection. It effectively removes unwanted reflections from non-metallic surfaces such as water or glass, saturates colors, and provides better contrast. The filter factor varies according to how the filter is rotated and its orientation to the sun or light source.

The 6.6x8.5" Graduated Neutral Density 0.9 Hard Edge Filter is another highlight of this kit. Fotodiox Pro 6.6x8.5" filters are the strongest in the industry at 2mm thick. They are guaranteed spectrally neutral to within + or - 3 in the a and b channels of the lab color space and are within + or - 2 in regards to total light transmission.

The WonderPana 145 Lens Cap, made from premium grade, high impact plastic, protects the front lens element when not in use. The WonderPana system is designed expressly for filtering UWA and WA lenses without vignetting, making it an essential tool for challenging shooting scenarios.
