As a UK customer ordering early, this product was dispatched direct from USA, we needed it for a tour of South America at the end of the week we ordered it, and amazingly it turned up in 3 days.
Having used the old GoPro - this version is better. Sharper, more options, and a more intuitive user interface.
You may find as we do that a large SD card will last longer than the standard battery, so we are looking at getting more batteries or perhaps the batterypac.
Video quality is great in 1080p @ 30fps or 720p @ 60fps. Personally i feel the 120fps to be a bit gimmicky as the resolution is like an old webcam. (when lets face it, anything that you want to show at 120fps is probably an action you want to see very crisp at the highest possible resolution) In this instance 720p @ 60fps and then slowing the footage by generating the extra frames in post is a better option.
Another minor gripe is that the mic input is on the side of the GoPro, which means from the standard open backed skeleton case, we cannot rig up our rode videomicpro to the camera directly whilst it is in its housing, which in a couple of instances would have been a nice touch.
Don't buy this expecting your shots to look as good as a dSLR with a good lens, the video compression rate on the footage is a lot higher than off a dSLR setup, the sensor size to capture the detail is smaller, and the lens has nowhere near the dynamic capabilities of a good dSLR lens... However, that is not what this should be compared to. When compared with cams like the ContourHD, yes the gopro looks odd, you may feel like an idiot wearing it, and there is a lot of squeaking from the plastic hinges when the ride gets a bit bumpy.. but the better low light, easy to use interface, easy expandability (there are a ton of accessories) and most importantly - the image quality mean that for all the shortcomings, we absolutely love this bit of kit, it's small so we take it everywhere with us.
If you are looking for a compact HD camera, with wide angle POV possibilities - in our humble opinion it is really hard to find a rival product on the market that ticks as many boxes as the GoPro HD Hero2.
