D|Focus filter adapter for Panasonic Lumix 7-14 f4.0 – designed for Blackmagic Pocket Cinema Camera users

By site editor Dan Chung:


One of the things I find most frustrating about the Blackmagic Pocket Cinema Camera is the shortage of reasonably priced wide angle lens options. The go-to option for many users is the Panasonic Lumix 7-14mm f4.0. There is a major drawback when using the 7-14 though – like most m4/3 wide lenses it has a petal shaped lens hood that make it near impossible to mount ND filters to the front.

Enter Dave Aldrich at D|Focus Systems. From his California machine shop he has created a great little filter thread adapter that simply slides onto the front of the lens and allows you to mount 77m filters. It is constructed of delrin and is secured to the lens using a push-on fit. This means you can mount fixed or variable ND filters quickly and easily.

The adapter works because it takes advantage of the smaller sensor of the BMPCC. On a larger sensor like the GH2 or GH3 adding the filter will cause vignetting (dark corners) and you can’t really use the lens any wider than 10mm. Aldrich claims that with the BMPCC’s higher crop factor you can use the full range of the zoom.


The best part about the adapter is the price. With a MSRP of $34.99 US this is surely a no-brainer for owners of the 7-14 and BMPCC combination. It is not yet available to buy but keep an eye on the D|Focus Systems website for availability.
