I know these action cams pack a lot into a small space, but the image quality that comes out is not amazing. When choosing one for recording my bike commute I could not find any decent comparison between different models.
I ended up having to base my choice on youtube comparisons (that had suffered from youtube high compression). I was mostly interested in ability to resolve detail even in low light, for example number plates. The Sony cams did seem slightly better, so I went with a HDR-AS15 (I don't need wifi, but the AS10 is harder to find).
But would love to see DPrev do a detailed review of several different models.
ssam: Would be nice to have some competition on image quality. 1080p does not necessarily tell you how much resolution the image will have.
I've just got the Sony HDR-AS15, as it seemed slightly better IQ than the GoPro (and i was very unimpressed by the gopro dmca incident). It still can't make out quite as many number plates as it ought to (I use it on my bicycle, because there are too many bad drivers around).
Yes, i can get most plates, but for example i can't read the plates on a red light jumper that i film yesterday.

pepelegal: "reducing the focal length without changing the entrance pupil increases the F-number. So, adding the speed booster to a 50mm F1.4 lens turns it into a 35.5mm F1.0"
F1.4 to F1.0 in photographic parlance may be an increase, but numerically it is still a decrease. DPR should be more careful with the wording, to avoid confusing us readers who speak plain English
F1.4 is actually short hand for f divided by 1.4. so f1.0 is bigger than f1.4 in the same way that a quarter is bigger than an eighth.
scott_mcleod: Before anyone gets too excited you'd all better read this (all of it):
I shall say no more... (except a thanks to Thom Hogan for pointing this out in his blog)
a bit like the bit in the canon 5dii manual that says that the h264 codec in it is only licensed for non commercial use.
