The headline feature is that the new GoPro 3 will do 4K HD resolution. And this is useful because? Nobody has 4K sets and nobody will for a while. Even if you do, the FPS is only 15fps. Hello? The 90s called, they want their 15fps back. Totally pointless.
On to the other features though, it will do 2.7K HD @ 30fps so atleast we have a "future" resolution at a usable fps. Still a bit pointless for me personally.
It also does 1440p though which some people are starting to take advantage of with higher res monitors. I guess to have the choice is all good.
Something to be excited about though are the new high fps modes for the ability to have awesome smooth slow motion footage for sports.
1080p will do 60fps(NTSC) / 50fps(PAL)
720p will do 120fps/100fps
The 720p at high fps is a nice feature.
They have supposedly increased lens performance again and other things. It is the Daddy the black edition, but for me, I will be watching the price of the older lower spec models which could be pushed down further.
Something I find surpising is the minimal difference between all of the other models though, including even the new GoPro3 Silver and White editions. If you only care for 1080p @ 30fps, and 720p at 60fps, then the following models all do that:
GoPro3
Silver
White
GoPro2
HD Hero2 Professional
Go Pro "1"
HD Hero Original
Obviously each new model has other features it adds, including a supposedly sharper/redesigned lens and better exposure algorithms each time. Surely an original HD Hero should now be bargainous and still shoot 720p @ 60fps quite well though?
