With its experience in the making of the NUANCES mineral glass square filter line, Cokin introduced in January 2018 two screw-in filter additions to the NUANCES mineral glass filter line: ND1024 (10-stops) and a Variable ND32 (5-stops) to ND1000 (10-stops) ND filter. Cokin soon completed these NUANCES screw-in filters with new references: Variable ND2 (1-stop) to ND400 (8-stops) ND filters, circular polarizing C-PL and anti-UV Protector filters. Screw-on NUANCES filters are available in 52mm, 58mm, 62mm, 67mm, 72mm, 77mm, 82mm diameters (and 95mm for the anti-UV Protector) and offer the same optical performance as our NUANCES square filters.
Some Cokin Pure Harmonie screw-in filters, introduced in 2012, are still on stock for some diameters. The technical specifications of this former range of filters have benefited the current Nuances range. You can find these anti-UV, circular polarizing and variable ND2-400 filters until stocks are exhausted at the following webpage: https://cokin.com/en/156-pure-harmonie.
Similarly, some diameters are still available in the Cokin Pure Excellence range, also introduced in 2012. These anti-UV and circular polarizing filters have a strengthened brass mount and a thick mineral glass with a multicoating process. The filters still available can be found at the following webpage: https://cokin.com/en/157-pure-excellence.
