Just ordered an A7R Mark III.
It's quite obvious I'd like to have back time lapse, smooth effects, digital filters, etc.
It's obvous, too, that this is a pro camera, and I might replicate most of the effects in post-pro. But many time it's for me critical to post immediate images on social media, and an internal engine to immediate process certain effects would be of great use, as it was on the A7R Mark II.
I can well imagine managing an app store is not easy at all, and maybe some security concerns got into place, yet in an historical moment where the A7R and A9 are finally moving the pro market from Canon and Nikon... well, this sort of camera customisation/extension might well be worth the investment!
Sony... just give your customers an answer about your strategic vision on this, either way.
Thanks
