Micro four-thirds and APS-C mirrorless cameras do a great job and are way more practical than their DSLR big brothers. Love taking my Canon OM-D on excursions.
Excellent deconstruction ot 48
My DSLR camera has 14 bits. Having a high dynamic range is useful in capturing a scene with both bright and dark elements. The new 4K-HDR TVs have more pixels, but they also have 10 to 12 bits of color depth (versus 8 for standard HDTV).
Humans can only distinguish about 30 shades of gray, so 256 is way more than anybody needs, unless you’re doing scientific research.

Since professional printing is still done at 2450 DPI, cameras still have a way to go to catch up.
I’m talking about dynamic range, rather than shades of gray.

Check out professional cameras and you will see they all have high megapixels and professional photographers are not taken in by hype.
...
Sensors in professional cameras are more sensitive to light, have higher dynamic range, less noise and more surface area than sensors in cheaper non-professional cameras. Professionals also put very expensive lenses in front of those sensors.
You’re a perfect example of the consumer that falls for the megapixel hype.

Moonman62,
I’m afraid you don’t know what you are talking about. I shoot with a Nikon D810 and used a D800 before that and several cropped sensor cameras before that.
If you thought I was saying that there was any equality between any phone camera and a Full Frame professional camera you misread what I said.
I shoot full frame and with what I consider an advanced design because I can get more than just sensor density or megapixels. If however you are talking about two phone cameras and one has 10 megapixels and the other 48, give me the 48.
There is no phone camera that will give you 14 stops of dynamic range or has the ability to push ISO out to 6400 and farther and still get a usable picture, there is no phone camera that I know of that has a 50mm f:1.4, or then an 85mm with f:1.4 or then again a 70 to 200mm f:2.8 or even a 150 to 600 4.6. If however you want to take a picture of your kids playing in front of some scene and you don’t want the whole scene in the picture at least with more pixels you can crop to get a usable picture without getting jaggies.
I agree with you. All other things being equal, yes I would take more MPs. However, all things are often not equal. For example Nikon’s top of the line pro camera the D5 has only 20 megapixels. Several of their consumer and prosumer models have more. Some much more.
I do expect them to introduce their next pro model with a lot more pixels.
While I understand why you would call the D5 the best, I would not agree. Certainly it is the fastest and most expensive but is not nearly best for landscape and portraits. The D850 is a much better camera in most categories. I don’t think I would call the 800 series prosumer cameras. There are many more pro’s shooting the 800 line than the d3, D3s, the 4’s and 5 combined. The big reason for their popularity is their awesome ability to crop
at 75% and still have tack sharpness. The D5 could do a wedding but the 850, 810 or even the 800 would do a much better job. If resolution doesn’t mean anything then you might as well just shoot with a 700.
I remember years ago, you would see more working pros using the N90s than the F4 despite the fact that the F4 was the pro model.
It will be interesting to see what the D6 has.
