Originally posted by Rondec The basic question (I guess) is which is more important frame rate or megapixels. The answer of course is neither. And both. But these days, the A7r III is doing 42 megapixels at 10 frames per second. Sure, the A9 can go to 20 fps at 24 megapixels, but you have to ask the question "Who needs 20 frames per second frame rate?" It is good a question as the similarly silly question "Who really needs 42 megapixels anyway?"
Other than hard drive space and slower (but still decent) frame rates, there is no particular negative to having higher megapixels and it sure does seem as though it is a feature that the average consumer does understand.
High megapixels are great for cropping potential. High FPS might snag *just* the right action moment as well. They both come with costs though. High MP means way more storage needed (RAW 100mb files) and less card space, less buffer for shots etc. It also isn't ideal if you edit and post on the fly with an Ipad. These days I do almost all my editing in Lightroom mobile on an Ipad transfering RAW through wireless. I specifically went after 24mb FF just to keep that process flowing at a reasonable rate. I don't print past 16x20 so the extra cropping would be nice but mostly wasted while actually hurting performance that I use every day. High frame rate means sifting through zillions of photos which is a time killer and wears out shutters much faster.
If transfer speeds didn't mean anything and storage, by all means why not keep adding resolution so long as the lenses can keep up.

Originally posted by Ontarian50 I completely understand and sympathize. But that's also a big reason why the camera industry is in the doldrums, and everyone's predicting doom and gloom. After a decade of rapid upgrades, and trade-ins to chase more megapixels and other features, we photographers are starting to wonder if we will live up to the potential of our 5 year old camera bodies, and anything newer is a waste of cash.
If every K-1 owner decides they have reached their limit, and every Nikon D-800 owner does the same, and every Canon 5Diii also ... well, it's not hard to see how the predicted 2018 unit sales don't look so good.
Especially when the phone makers have something shiny and new to show off every few days.
I think we'll see a big slow down. I've upgraded body's a bunch of times in the last ten years. K7 to K5, huge jump in ISO and DR. K5 to K3, big jump in resolution (not really needed though) and AF got much better in low light, camera was also faster to operate. I skipped K-1 as I don't want larger files for my editing process and wanted a longer reach than 450mm. Went D750 to get the AF and lens I want. Where I'm at now I've got great AF, great DR, great ISO, enough resolution to print any size I'd want. I think many people are in that same happy place with the newer body's just not showing a big leap in performance like they used too. Like the D850 for me, no need to upgrade as the cheaper D750 fills all my needs.
It's sort of the same scenario gaming computers had in the past. You would upgrade every year because performance was increasing so fast. Now a PC will last 5 years and everything runs great on it. I see the same time gap happening with Camera bodys unless they introduce features that are very attractive to lure us into another body.
Sensors are all getting to the point now where they do well up to ISO 6400 (even M43) and all of them get good results. I've got prints around the house from multiple systems and nobody but me knows what came from which.
