New Gear – MagFilter RX100 Filter

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.

    @al - Thanks, this was a really old article. I've updated the links as the product is still available on Amazon.

    Ah, sorry, now I see the adapter uses same metal base as the CPL just ordered.

    Also, I guess I should clarify as "For cheap buggers already overloading their phantoms w/ an hx9 etc who don't want more weight". Just wondering if there's a thin film type nd or something that's not horrible.

    No weight listed, though the adapter itself looks lighter than a 52mm filter, so maybe it'd still be flyable.

    P.S.: Thanks for the reliable reporting, Emm. I've come across a few gems here. Several items in our little film trailer are cheesycam-sourced (including the aforementioned HX9 that's filmed alongside our 5Ds).

    @5_O'Clock - The option is the MagFilter with Threads. You can then use any ND Filter or your choice.

    Hmm... just checked with carryspeed. Still no ND filter, and no plans to make one.

    Too bad, this is needed for those of us sending hx9/rx100 on aerial rigs. Any alternative ideas?

    @Rade - ND Filter will be soon, but if you were part of the newsletter, there was another announcement made over a week ago httpss:// You can use your own filters.

    @Glenn - I believe International will be handled by distributors, or it will follow soon after first release.

    @Steven - Just need to try it out. These two sizes seemed to cover most cameras on the market. I walked around Best Buy trying them on different cameras, but can't remember which could fit the SX40. Maybe one of them does, I will have to try.

    Registered my intent to purchase. Awaiting next step. Will interested parties be contacted when stock is available? Or do I need to keep visiting the carry speed website?

    @Emm - I understand. But I expected to see a way to "place" a order and then have it filled when available (later this week). No worries. Thanks for your prompt response as usual.
