Sorry for the long wait, but here is the official announcement about the new MagFilter System . This is the Polarizer i've been using with my Sony RX100 cameras. I was able to help with some ideas on this fast and simple filter solution that can be used with many of today's high end compact cameras, while leaving the camera virtually unaltered.

The MagFilter System uses strong magnets within the Aluminum filter body, and attaches to the front area of high end compact cameras systems with a very thin metal ring that adheres to the camera.

Using high quality coated glass optics from Japan, the Polarizer is the first MagFilters that will be available this week. There are two different sizes that can support a variety of cameras. The 42mm MagFilter works on cameras like the Sony HX9V, HX10V, HX20V, HX30V, and of course the new Sony RX100.


The smaller 36mm MagFilter works on cameras like the Canon S95 and Canon S100. I've been testing the Polarizer for a few weeks, and it works to cut glare from reflective surfaces such as water, glass, leaves, and even helps retain information in the sky.


One thing I noticed is that the Sony RX100 seems to retain more details in the shadows when using the polarizer, possibly because it cuts down on those specular highlights in the scenery. With very bright highlights, the Sony RX100 will try to retain this by slightly underexposing. With the highlights being controlled in the scene, it seems like you can get a more balanced exposure - at least that's what i've experienced in some of my tests.

Just a quick over view of what to expect on this dslr matte box. This particular one is fairly well made with just a few quirks, but it's definitely a hundred times better than the cheap plastic one floating around. If you're really into the aesthetics of your rig, I suggest going for this. The FilmCity MatteBox is mostly metal including the flags, top sunshade, 15mm clamp, and donut ring. The hood itself is the only thing made from hard plastic.

The flags on the Mattebox will not fold up for storage, but it breaks down quickly to be packed away. The top flag will tend to get loose with constant positioning and would require the allen key to re-tighten. The side flags can easily be tightened by hand through the thumb screw. The single filter slides in an out with ease, and can be locked down quickly. It does not rotate so it's not something to be used with a CPL. The mattebox does not have a swing away design, so to make things simple, keep it at the end of your rail set. Yes it does require rails to mount. If you've got the money, I suggest going for the more expensive versions with a swing away design and the ability to rotate filters. One that some consider is by TrusMT found here: Trusmt DSLR MatteBox Carbon Fiber or Aluminum.

Considering the prices of current matteboxes, overall the FilmCity is one of the cheapest with decent quality build (again much better than the uber cheap plastic one). Can be found on eBay (click here).
