It's always about the right tools for the job. That's all I've been saying in this thread, I'm more of a ~24MP person, others want to maximise to achieve their specific requirements. An Exception wants the best, and I don't blame him for his choice. Of course that doesn't mean that great work isn't also being done with alternative gear that is available
All I want is around 16-24MP covering the APS-C sensor region, the upshot of which is 36-56MP in FF. Is that needed in FF , NO, but Lr makes it easy to export to any lower resolution I want and I get the advantage of better micro-contrast, edge definition and detail, and less obtrusive noise by downsampling from a higher resolution, with no cost involved.
