Gopro modifications

[grizzlyadams23]

I know that Gopro's arn't exactly professional grade cameras but still are nice for their size, durability, and cost ratio. The only thing I cannot get over is the fisheye lens, If it had a zoom, wide angle, or infrared lens I feel like it could be a very versatile platform for conditions you don't wanna put your best camera in. I was wondering does anybody have any info on other lenses that can be put on these cameras?
