They would sell at least 1 of those cameras... to me
Fashion photography for sure: it has long been the territory of slow and high-res medium format backs. There's no such thing as too much resolution in fashion photography.
For me the downsides of higher res are:
- the need for better shooting discipline
- bigger file sizes
- longer processing time in post
- lower FPS (the latter not being a factor in some use cases).
Noise is less and less of an issue with modern AI NR and one can always downsize in low light and still enjoy the higher level of details when the light is good.
And after using a 1D X, I had come to love the ergonomics of gripped bodies.
As others I do not see the logic of an R3 II being a fast low(ish)-res body since that would cannibalize the R1 which has some time to go before a R1 II appears.
