We have all seen some incredible footage taken with GoPro cams. I’ve had an opportunity to record some rides with it, and almost bought it, until I saw this – a detachable 180 degree wide angle fish eye lens. My first thought was “this is another crappy Chinese plastic”, but I’ve decided to give it a try anyway. A few weeks later (it took dx a long time to ship it, usually doesn’t take that long) I finally got a chance to test it. Since it was a rainy day, I couldn’t test it on a bike, but already from a footage taken in my room, I saw that this was definitely worth $17. A few hours later, I gave it a spin in the neighborhood, and it only proved my point – this lens is epic!
