Camera Gear

Constantly dealing with camera gear and constantly being disappointed with tools out there, we decided to design our own. Check out some simple tools but essential for every kit that we’ve designed, based on our daily needs.


Meet the brand new Wide Open Camera Mount for All GoPro cameras. We worked with Snake River Prototyping to bring this bad boy to you. The base and arms can work with all GoPro cameras. The mount is modular and can work as a base unit only or with one or two arms to mount in various positions. The base retails for $45 US and the arms are $23 each.

    International orders are an additional $25US for USPS priority shipping. Please contact us for any specific requests. Thanks!.

WOC GoPro Camera Mount

Coming Soon




The BlurFix3™ SO Naked slips over the GoPro® Hero3 housing and allows you to mount 55 mm filters to your camera! This adapter is precision CND machined our of Delrin® which is more expensive than billet aluminum but flexible enough to allow for a precision clipping mechanize. This is the same frame that is sold with the “BlurFix3 SO Featuring the CYD Dome filter by URPRO” only without a dome filter.

Note: Camera and filters sold separtately. Not compatible with the Hero or Hero2.


BlurFix3 Micro 52

Now you can adapt 52 mm filters to your Hero3 camera when using your camera without it’s housing! This adapter was made for weight critical applications. You can mount a Neutral Density filter on your Hero3 while flying your quadcopter to minimize or eliminate the “Jello Effect”. This adapter is precision CNC machined out of Delrin(R) for ultimate durability.
ATTENTION: Installation and removal of the BlurFix3 Micro 52 are done at your own risk. Snake River Prototyping is not responsible for any damage to your camera that results from use of this product. Caution during installation and removal is advised.

The fit of the BlurFix3 Micro 52 varies slightly from camera to camera. If the desired fit is too loose, thin tape may be placed on the outside of the camera lens body to act as a shim. Use caution as damage to the lens body may occur.
DO NOT rotate the adapter as damage to the camera lens body may occur. Remove the adapter by pulling on it without rotating. Only press the BlurFix3 Micro 52 on as far as necessary so that it does not fall off during normal use.


BlurFix3 SO 55mm Filter Pack

All 55 mm filters are ultra-low profile to limit vignetting in all Hero3 video and camera modes. This filter and BlurFix3 SO Naked combination pack is ideal for general aviation, motorsports, snowsports, paragliding, fishing — any sport requiring the reduction of glare or the desire for forcing a slower GoPro® Hero3 shutter speed.

Additional Information


– Allows you to mount a 52mm or 55mm filters to your Hero3
– Compatible with “The Frame” mount from GoPro®
– For use with the Hero3 without the housing for lightweight applications (i.e. RC multi-rotor & aircraft)
– For use with external microphone (i.e. pilot headset in aircraft)
– Easy friction fit
– CNC Machined Delrin®

Testing Notes:

No vignetting observed in any mode below water using the ultra-low profile URPRO color-correction filters (CY, GR, and SWCY) available from SRP. There is vignetting in 960p WIDE video mode and photo mode above water with these filters, although they are intended for below water use only. The magnification factor under water removes the vignetting underwater in all modes. 

For above water use, the ultra-low profile Marumi CPL, ND4, and ND8 filters offered by SRP will have mechanical vignetting in 960p WIDE video mode and photo mode. Depending on the camera there is little or no vignetting in the WIDE WVGA, 720p, 1080p, and 1440p modes. Off-the-shelf 55 mm filters have not been tested by SRP, however, due to their high profile we anticipate that these filters vignette in all modes. We have tested the BlurFix3 SO on a variety of GoPro(R) Hero3 White, Silver, and Black cameras. The above observations were made using this small sample lot of cameras and Snake River Prototyping will make changes to our vignetting guidance, if necessary, after further testing and customer feedback.

    do you guys do express shipping within the us?

  • Paul Golden

    Can you guys list out the exterior circumferences (or lengths ) for each of the sizes of the HIR lens gears?  SML is not very informative.  

  • Planetearth

    How do you get information here. Don’t know how to size for my lenses without any details on the product. No contact number either. Little hard to order these if you don’t know what is right for your lens. 

  • marcjef

    Is there a way to get expedited shipping on lens gears?
    I have a shoot this week (Tues- it’s Saturday now).
    I cannot find any contact info for the estore.

  • marcjef

    Well, seeing as how you posted this a month ago…
    I guess I shouldn’t hold my breath on getting a response.
    I ordered the basic set to test out. They are good but took
    over a week to receive. At $18 a pop, you guys should be a little
    more responsive.

  • marcjef

    Amazon is same price individually, but no 3 for $45 deals.
    Also no way to tell what shipping options are there either.

  • marcjef

    An Amazon checkout test says the only option is 3-5 days at
    $4.50 to ship one gear.

  • Jared Abrams

    Sorry that we missed this. We can ship via paypal purchase on our site. Filmtools also has them if you need expidated shipping.

  • adi

    Lens Gears arrived today. Real quick delivery to Switzerland. The One Size Fits all really fit on my lenses. So I can change real quick fm FollowFocus Mode to Freehand. Chapeau!

  • marcjef

    how about in LA? is there a local retailer?

  • Jeremy Widen

    Agreed. I got a set of these, and they really help. I also got the red ones, so it’s really easy to tell my lenses from others when I work on multicam sets.

  • Goforjared

    Filmtools and Birns and Sawyer.

  • @BrentwGraham

    I’d like to get some lens gears before next weekend. Is there a retailer in Austin Texas?

  • Terry

    I have several of these gear rings in red but I I need a slightly narrower gear for one of my lenses. Does the med+ come in red?

  • Goforjared

    no only the WOC gear is red. Sorry about that. 

  • Ingvild Røverdatter


  • Derick

    Did you guys take the sizing chart for the lens gears off your website? I can’t seem to find it anywhere. What size lens gear would you recommend for the Canon 50mm f1.4 or f1.8? How does shipping normally take? Thanks!

  • Tim

    I was looking for a gear system that was low-profile so the lenses would still fit into my travel case.  I’m glad I found your company and the Zip Tie Focus Gears.  I wanted to add my three lenses to the list:
    Nikon 17-55 f/2.8 – M+ Lens Gear
    Nikon 28-70 f/2.8 – WOC Adjustable Lens Gear (just snip off the last 3 teeth)
    Nikon 80-200 f/2.8 – WOC Adjustable Lens Gear (just snip off the last 3 teeth)
    And thanks for your super-quick delivery too.

  • Ryan W.

    Any kind of deal if I am buying a 3 pack of the adjustable lens gears, an ND fader and Polarizing fader?

  • Bob

    Hi guys…i have a Zeiss ZF.2 lens set (25,35,50,85 – 25/35/50 are 58mm and 85 is 72mm diameter) and i want to know which ones to purchase. I want the wider lens gear as possible, not the thinner.  Can i fit the wider in my 58mm diameter lenses? Is that an option, the ”one size fits all zip gear”? Is this possible to fit also? thanks

  • Leonpierri

    anyone to answer the question? I want to know about it also..

  • Familyaffairdenver

    I ordered the wrong size, can I exchange for the right one if I pay for shipping back to you?

  • Goforjared

    Yes. It will work on that lens. Sorry for the late reply.

  • Ploko

     Hey, I just bought several Medium + gears and some bonehead put Large gears in the packaging instead. They don’t fit and now I have to waste a day braving LA traffic for 3 hours to return them to Film Tools.

    Not too happy about that…

    Both packages were mislabeled, these are 10.04″. You might want to check inventory to prevent other people from having their day ruined as well…

    I bought one Universal as well but it’s too wide to work on all but one of my lenses.

  • Stamm

    i am looking for the same question answered.  i Ordered the wrong size, i did not notice the additional information tab. can I exchange for the right one if I pay for shipping back to you?

  • Allprohd

    Bought them at BH and really like them! Got the wide ones and they work perfect for all canon L zooms and primes and all Zeiss ZF primes. Nice product.

  • scott

    Do you have all the lens gear sizes in stock? Film Tools carries them but are out of some sizes and have waited weeks to get them from you. I’d order them here but if you don’t have in stock there’s no point. Is there an actual email contact for your company? Doesn’t seem to be one and most of the postings below have never been answered. Concerned. Thanks.

    you want to send invoice. thanks heaps

    Will the Wide Open Camera Mount work for the Hero 4? And what keeps the camera housing held in? Compression?
