Rollei ND 100 mm filters are supplied with a 2mm thick foam seal as standard. This layer prevents light from leaking in between the filter and the filter holder, and this can ruin the photos you have laboriously planned. This protective layer has to be made from soft foam material so that the precious filters are not damaged in the enormously varying light levels while they are being inserted. The foam itself, though, is unfortunately not immune to accidental damage or mishaps. The foam layer’s primary purpose is to prevent light from percolating through at the sides. Its protection of the filter itself is a secondary function.
Set of three as immediate spares and back-up on extended photo trips
Professional photographers aren’t alone in knowing just how small, sensitive individual components can jeopardise a whole shooting session. This is why we are offering you this spare as a practical set of three foam seals so that you can be prepared for any situation or challenge when you are away from photo replacement facilities. The foam seals consist of 2 mm thick rectangular sheets which are die-cut to precisely the right dimensions. When replacing them, all you need to do is to place the seal exactly over the filter and then remove the lower one. These foam seals are suitable for Rollei 100X105 mm BD filters; the intensity of the shade of grey has no bearing on their fit.
