GoPro HD Lens Mod - No Fisheye - June 9, 2011, 09:40 PM

In my search for a helmet camera, one of the biggest things that bothers me about the GoPro HD is the fisheye angle... I just don't like it. However, this may be a solution and might convince me to get a GoPro HD...
Anyone who has GoPro vs Contour experience chime in (or even the Drift HD170)




GoPro HD Hero Lens mod. No fisheye!!! - RC Groups

See post 65 in this thread. The microseven lens will not work!!

The lens used is from Sunex. Its not listed on their site as its a custom design.

part number: DSL355A-650-F2.8 with IR cut off filter.

Sunex optics-online.com - CMOS miniature and fisheye lenses

I sent a request by email and then made a phone call to them after which they shipped me one. Cost was 49dollars. Only problem is they insist on FedEx so shipping to Ireland cost more than the lens!!

FOV is 80 and 100degrees depending on shooting mode.

It's the only option I could find that will work on the GoPro. I think it was worth it.

Origional lens is loctited pretty good!!! The case opens by removing four screws. tutorial on case opening is posted on youtube. You need to do this to remove the front cover to allow the lens thread off.

Wrap the origional lens body in some masking tape to protect it and unscrew it. Once unscrewed care must be taken not to allow any of the old loctite fall down on the sensor. The thread is extremely fine so it's very easy to cross thread the new lens. If you feel any resistance on the first few turns when putting on the new lens then back it off clean the threads and try again. I just eyeballed it and took it slowly. I also cleaned the threads in the camera housing before I started to try and remove the old loctite.

Next you need to hook up the output to a HD TV and enable live view so you can adjust the focus of the new lens.

Hmm, interesting. The fisheye of the Hero does annoy me often enough that I'd consider something like this. Good find!


How's my posting? Please direct all concerns and inquiries to DCSBN's chief content manager, Hollywood, via PM.

Nice find. The fisheye lens on these lower end mini cams annoy me as well.

Sidenote: Nice vid. I still wonder how everyone is doing these smooth flying/floating single take shots lately. It seems everyone is doing them but I can't see shadows from a gimbal or wires, and I know even with a Steady Cam you couldn't get the elevation changes.

The answer is ~1:38 in that video above. See if you can spot it And check out more of the Vimeo vids from that account. The answer's there!
