P-Series CC30Y yellow filter
The Cokin P725 is a P-Series resin filter that provides CC30Y yellow color compensation for film and digital photography. It is intended for photographers who need precise color-balance correction when shooting under mixed or deficient lighting. The filter mounts in the Cokin P-series holder system and is not suited for screw-in filter users or for lens diameters outside the 48-82 mm adapter range.
Vignetting control with wide angles
When used with focal lengths such as 20 mm, 24 mm, 28 mm or wide-angle zooms covering 24-50 mm, 28-85 mm and 35-135 mm, the filter helps eliminate dark corner vignetting. The slim P-Series frame reduces mechanical obstruction at short focal lengths. No optical coating or transmission data is supplied, so flare resistance and light-loss figures cannot be stated.
Color compensation and light-source correction
The CC30Y designation means the filter attenuates principally the blue portion of the spectrum to shift overall color balance toward yellow. This allows fine-tuning when a color temperature meter reveals a slight variance in the illumination source. No additional accessories, pouches or software are bundled with the filter.

Questions about this item
How do I mount the Cokin P725 CC30Y filter and avoid vignetting at 20mm?
Slot the resin filter into a Cokin P-series holder with the correct adapter ring for your lens diameter; the system is designed to prevent dark edges even at 20mm focal length.
Does the yellow CC30Y resin filter need periodic replacement or special cleaning?
Clean gently with a microfibre cloth and lens fluid; the resin material can scratch more easily than glass, so store it in its protective pouch when not in use.
At what focal length does vignetting first appear with this P-series filter on a wide-angle zoom?
The P-series holder and filter are engineered to eliminate vignetting down to 20mm on full-frame; vignetting typically only appears if you stack additional filters or use an incorrect adapter ring.
