Raven internal 6 x FS-ND kit

Our ND filters are created using sophisticated coatings rather than dyes, for more accurate colour and exposure control. They filter visible and infrared light equally, meaning that your camera’s native IR response is attenuated equally to its visible response. This is more consistent than adding a simple IR cut to a dye-based ND.

Colour neutrality across all six filters is excellent. Moving between the filter strengths no significant changes will occur. There is a small but balanced shift moving from no filter at all to using an ND however, so in this scenario we always recommend capturing a colour chip chart in your shot to make matching simple for your colourist.

No configuration is needed in camera to use the filters.

The rubber flange fitment works like a ratchet – easy to insert and difficult to remove. It will never shake loose, even under extreme vibration.

Unlike our OLPFs, these NDs are designed for very regular handling in any environment. They have a hard scratch-proof surface, with a water rejecting coating. Cleaning them is trivial with any soft tissue, cloth and regular lens cleaning fluid. The glass is thin, so avoid undue pressure.

The back focus shims are only required if you need to maintain accurate focus marks, or hit a very specific minimum object distance. Most stills lenses do not have sufficiently accurate markings for this to be a problem. Due to the optics involved, you will always be able to reach infinity focus, even if you don’t use the shims. Remember to remove the shim if you completely remove the ND, as that could result in an inability to find infinity focus.

The standard flat rate worldwide shipping we offer is via the UK Royal Mail. The International Tracked and Signed service partners with the national carrier in the delivery country for cost effective tracked delivery. In Europe 3-5 working days and worldwide 5 to 7 working days are required for delivery. We insure the packages in transit independently, and the on-time delivery success rate is over 95%.

We are happy to ship via Fedex or similar when necessary. Contact us via email with your order number to establish cost and shipping time.
It is cheaper in most cases for us to ship and pass the cost on directly, than to use a customer’s shipping account, due to the relative cost for export vs. import shipping, and due to insurance requirements – we insure independently to reduce shipping cost.

Please refer to your customer account and notification emails for a tracking number. In some cases packages that cannot be delivered during working hours are held by a local delivery office, pending customer response to a letter that is posted to them. This can greatly slow down the process – please check your tracking number regularly and contact us if you have queries. Once a parcel reaches its destination country, detailed tracking is taken on by the national postal service rather than Royal Mail.

If your package has not yet shipped, please contact us by email for an estimated lead time.
