- Owners of the original BlurFix can use this filter adaptor with all of the 55mm filters that they have already purchased.
- No vignetting 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.
