My goPro can get 30 and 60 fps full HD out of 12 MP. I can't believe, Canon can't get 60fps out of 20 MP full HD with the 5DIII hardware. But i don't understand that Digic-thing.
The chipsets in the devices are fairly different. The DIGIC is designed to be able to transfer and process high quality JPEGs and RAW files, process AF and so on. There is a lot going on in the processor. As well, no offense to cannon, the ASIC DIGIC is probably relative low volume compared to the processor in the GoPro which has a highly optimized MP4 compression engine, using a TI OMAP processor or such.
As well scaling, processor like the OMAP have a dedicated scaling stage to feed into the mpeg4 codec, where the older DIGICs might not. As well, the OMAP has a DMA engine that is made to optimize putting together mpeg4 frames, really cool, again I doubt the older DIGICs do.
The new DIGICs probably have this.
As well, their is a quality difference, Canon must be very high, where the GoPro can't get away with a bit more loss.
From what I understand the 1Dx-ii is goign to have a top notch mp4 codec, no??
Anyway, from what I gather from the experts on the forums, 4k on the 1Dx is a must have that will only be a handy to have for many of the owners, who need the AF and stills on it.
I've opined that the 5D-iv will have a 25.1-26 MP minimum, to allow for a 1.5x scale down to full width 4K.
I also bet, at some point there could be a firmware upgrade to do a full width 4K on the 1Dx-ii, when they get the scaling in the pipeline proven out.
Anyway, if Canon can get 8+fps, 25MP, AF as good or better than the 7D-ii, DPAF, ***, and one chip ADC, and close to the $3K mark, I'm in. I am guessing they have the heat problems sorted out in the 1Dx, really thermodynamics in consumer electronics is a well modeling art now. Look at laptops, and tablets, stereos and such. Car stereos would be an interesting one, keep the dust out. But I digress. Just want to say tools like Solid works and the available models have come along way over the last 5 years. There is no reason that they can't do rapid mechanical design. So shame on Sony for failing that checkmark!
Anyway, I'm tired of the 50D and 7D I have. I keep on pushing up against the noise wall when I am doing indoor sports and some evening photography with moderate movement.
I want to jump to FF, but it's got to be compelling. For my video needs, the 5D-iii is not quite there. I really want DPAF.
That is my $0.02.
