We're proud to introduce the Essence Rear Magnetic Filter for LPL mount.  Designed to work with vintage lenses modified with Simmod’s own LPL mount conversion kits, the system offers incredibly quick and easy diffusion filter changes. Once installed changing filters takes seconds with each Essence filter popping into place with a reassuring click. It also has the advantage of being smaller and lighter than screw-on or matte box mounted filtration. One small single filter size fits multiple lenses and there is no need for heavy matte boxes, multiple step-down rings, or larger more expensive filters for wide angle lenses. Magnetic Pilot is included.





* Reduces highlights and lowers contrast

* Creates a cinematic look

* Softens wrinkles and blemishes

* Creates a soft, pastel-like quality

* Softly diffuses light

* Resolution is maintained while contrast and sharpness are understated




    ***Please allow 3-5 business days for engraving***
