This is a big reduction in the price that Amazon has done (about 80-90 discount) made me decide tested the hero black edition 4.
At first I was a little disappointed with my final choice on the septic and 4k 30fps in its proposed because it was the only advantage she had over the silver edition.
Then once in tests I was very pleasantly surprised by the sharpness provided by the camera in 4k, the picture is really very clear, and much prettier and dive than on previous versions.
I, who practice the photo / video pro SLR and am a big fan of quality images, I must say that I really enjoyed seeing the performance of the hero 4 edition.
For those like me who are undecided to purchase one of the two camera (silver or black) I recommend Black to anyone who wants a high quality look and are willing to give up a touch screen and has a battery life X2, as you will be surprised by the resolution and image quality.
For those grants slightly less important to 4k, the silver is then made for you, because the provided image quality is very good too, even if it is only 2.7 K. max qu'exploitable .
I specify that the battery GoPro Hero 3 is not compatible with Series 4 heroes.
I put only 4 stars because the price is not justified for all the options in less than a black relative to the silver that ultimately is very close to the black but in addition to a screen and a proper autonomy.
Amazon Service 5/5, he replaced me die the day after the first gopro I received with a molding defect on the closure of the box. (The clip was hanging)
