GoPro 3D with Sunex (no fisheye) lenses

I've swapped out the fisheye lenses on a GoPro 3D with a pair of Sunex dsl355a-650-f2.8 lenses. See this thread. Lens adapters for GoPro?

The original fisheye lenses are okay for action video, but are very limiting for general 3D video. The Sunex lenses are wide angle, but not nearly as wide as the fisheye lenses, and they don't have the extreme barrel distortion. They deliver very nice images. The advantage comes in working with the GoPro 3D system, with the camera mount, the syncronization, and the GoPro Cineform Studio software. The files are also compatible with Cineform Neo and Neo 3D, and can be adjusted for 3D and with all the FirstLight effects.

Changing the lenses is fairly straightforward; see the video in the referenced thread. Getting the lenses in good focus was a challenge - the GoPro LCD gets you close, but then it takes a series of photos and lens adjustments to tweak it in.

I'm using the GoPro in the process of learning 3D. Seasoned 3D pros might want to consider something like this as a cheap B cam to mix in with the main cameras.

Great stuff!

Looking forward to seeing a bit of footage. We got ourselves a couple of 3D Hero kits here so im definitely going to try this.

Thanks Charles.

Re: GoPro 3D with Sunex (no fisheye) lenses

Looks pretty rad. I'm assuming, from the looks of it, that this compromises the waterpoofness, and the dome lens cover thing doesn't fit back on?

That's right. Ian Newland, who suggested this approach to me also built an extension to accomodate a dome lens for his normal GoPro, not a GoPro 3D. For what I'm doing right now I don't need waterproof - if I do I'll work on adding an extension.

Here is a 3D YouTube video I put together that some might find interesting.

I put the Sunex lenses on the 3D Hero months ago and am glad I did.

Re: GoPro 3D with Sunex (no fisheye) lenses

The biggest issue I have with the GoPro 3D Hero is not being able to monitor the output and see where the heck the thing is pointing. I shot a lot of video with it mounted to my head that potentially could have been good but was ruined because it was not pointed accurately enough.
I need to design a new case that will allow me to get to the composite video outs so I can monitor it with a small LCD monitor that I have.
While at it I think I'll see if I can make the IA adjustable also.
