Having been using multiple single cameras for a long time i cant tell how much i look forward to get a dual channel camera, and since its too early for the next big thing, then a dual channel camera with IMX 291 both ends must be the pinnacle of things.
If i could get 1440p or maybe a little more, then i might take it though the increase in resolution over 1080p are not really jaw-dropping in my book, daytime / prime time footage can still be improved i think.
4K would off course be what most will then say and i cant disagree, but then you will just have to remember that the night time footage while not useless will set you back a year or two compared to the evolution of 1080p sensors.
Needless to say even with a dual channel camera in my car, then you will probably still find a lot of single cameras in it too, but i think the dual channel will fast become my go to camera for F & R footage
Testing on the 0906 it fast ended up being the goto camera, not just cuz i was testing it and often had to look at the footage, but just the shear convenience of getting 2 cameras on 1 memory card.
