The ABT cine Rear Filtration Mount PL for RED DSMC2 allows filters to be used independently of lens and focal length between camera and lens. For release, there are filter sets that mimic the look of front diopters, but without changing the flange focal distance and focus settings. These correspond to the look of +0.5, +1 or +2 front diopters.

More effect filters will be added later this year. Also, a Clear Glass filter will be included if no effect is desired.


The Rear Filtration Mount was created at the request of the Danish rental house A Camera, in response to increasing customer demand for a special look. Many cinematographers use front diopters to reduce the imaging power of lenses towards the edges and create a “brine effect” – while maintaining constant sharpness in the center, as this look is reminiscent of vintage lenses.

However, for this particular application, diopters bring problems – the closest focusing distance shifts, it is no longer possible to focus to infinity, and the lens focus marks no longer match the object distance. With the Rear Filtration Mount and its various filter inserts, it is possible to achieve the desired optical effect without shifting the focus.


How it works
  • The Rear Filtration Mount for RED DSMC2 screws onto the RED camera instead of the original RED PL mount
  • Compatible with all RED DSMC and DSMC2 cameras except the RED Raven
  • The flange focal distance remains effectively unchanged, so all focus markings remain valid
  • The mount covers an image circle of 46.31mm (RED Monstro, ARRI Alexa Mini (LF), Sony Venice)
  • Positive Lock to securely lock lenses onto the camera
  • No modifications to the camera are necessary
  • Some lenses cannot be used due to their back element protruding into the camera. Please print the test without scaling to test your lenses
  • Housing made of black anodized aluminum
