Colour Cast Performance

The X4 CPL is the most colour neutral CPL and features the lowest colour cast of any CPL on the market.  Compared to industry leading manufacturers of both drop-in and circular CPLs, the Canon Drop-In CPL has a very neutral colour cast and an impressively flat transmission profile.  Still the X4 CPL moderately outperforms the Canon Drop-In CPL in colour cast, maintaining both a slightly more neutral performance and higher overall light transmission.

Light Transmission Performance 

The X4 CPL features the highest light transmission performance, even when compared to “HighTransmission” polarisers by B+W and Tiffen.  Higher light transmission allows more light to pass through to the sensor which translates into faster shutter speeds, sharper images and the ability to use a lower ISO when shooting video.  The Canon Drop-In CPL features an impressive average light transmission of 40.59%, which outperforms every filter manufacturer, except for the X2 and X4 CPL.  X4 CPL average light transmission is 47.18%, while the X2 CPL has an average of43.86% which moderately outperforms the Canon Drop-In CPL.
