I have a love hate relationship with GoPro cameras. I have to use them on more and more of the productions I am on and in some cases they are exactly what I need and other times I loath having to use them.
One of my biggest issues is the lack of inter-changeable lenses. I want to be able to match the footage I am shooting as best I can in camera so everything cuts together as seemlessly as possible in post.
Since GoPros give you the ability to choose your field of view in the camera this has been my limitation. However, recently I ran across a small varifocal zoom lens for GoPro cameras.
It is a 2.8MM-12MM Modified Lens from RageCams. The usable focal range is 3mm-10mm unless you want to use shims or O rings to dial in the lens to a different focal range.
The biggest drawback is that it only currently works on GoPro 1 and 2 units and not on the 3 or 4 models as of yet.
Check out this sample footage shot on a GoPro2 with this lens.
Is this a lens you would consider adding to your tool chest? Happy Shooting!
Zoom Lens for GoPro: Gopro 12mm lens
Test video shot on the gopro hero 2 with 2.8-12mm RageCams zoom lens. Film look done in Vegas pro.
Special thanks to Mwaala Kalenga from Namibia showing macro focusing & cinematic examples from this lens.
Varifocal lenses allow you to adjust the range of focus on your camera from wide angle to narrow view. Simply twist the lens to zoom in or out or to focus in on any object at any range.
