This actually made me curious about the 5D Mark IV which I bought years ago, full price, and its predecessor, III; both launched at $3499 4 years apart. (2012/2016)
The IV is such a better camera for video (even with its faults) so in this case the video technology didn't make a difference.
It's all over the place.
I feel like the video capabilities have only ever had a marginal impact on pricing and marketing of photo cameras, except in the case of video-specific models (s1h, gh5s, a7s). In other words, photographers won't be buying an A7SIII for $3500. Or probably at any price
