(Megapixels) War...what is it good for....

[Kayaker72]

Just updating this table with the actual R5 pixel counts. Only a very minor change.

Camera	Megapixels	Horizontal Pixels	Vertical Pixels	Horizontal PPI at 24 inches	Horizontal PPI at 24 inches	Horizontal inches at 150 ppi	Vertical inches at 150 ppi	Horizontal inches at 300 ppi	Vertical inches at 300 ppi
5DIII	22.3	5760	3840	240	160	38.4	25.6	19.2	12.8
5DIV	30.4	6720	4480	280	187	44.8	29.9	22.4	14.9
1DX III	20.2	5472	3648	228	152	36.5	24.3	18.2	12.2
R5	45	8192	5472	341	228	54.6	36.4	27.3	18.2
Rumored High MP	82.7	11136	7424	464	309	74.2	49.5	37.1	24.7
7D	18	5184	3456	216	144	34.6	23.0	17.3	11.5
M3	24.2	6000	4000	250	167	40.0	26.7	20.0	13.3
M6 II	32.5	6960	4640	290	193	46.4	30.9	23.2	15.5
G7X II	20	5472	3648	228	152	36.5	24.3	18.2	12.2

With small birds, I am finding myself some of the time cropping down to ~1/9th of the frame. Smaller than that, regardless of the number of pixels, AF precision and the grain/size of noise becomes more of an issue. So, I also played with those numbers:

Camera	Horizontal Pixels	Vertical Pixels	Megapixels	Horizontal PPI at 24 inches	Vertical PPI at 24 inches	Horizontal inches at 150 ppi	Vertical Inches at 150 ppi	Horizontal Inches at 300 ppi	Vertical Inches at 300 ppi
5DIV	2240	1493	3.3	93	62	14.9	10	7.5	5
R5	2731	1821	5	114	76	18.2	12.1	9.1	6.1
Rumored R"HP"	3712	2475	9.2	155	103	24.7	16.5	12.4	8.2
1DX III	1824	1216	2.2	76	51	12.2	8.1	6.1	4.1
M6 II	2320	1547	3.6	97	64	15.5	10.3	7.7	5.2

So, take it as you will. I think, if I do get a new camera, my next camera will be more about AF speed/tracking/precision. Personally, it really would take something extreme like the rumored "High MP" camera to make much of a difference to me in terms of megapixels. If Canon could pull that camera off with even 5 or 6 fps, then you could still get a 24x16 inch print at 150 ppi when taking 1/9th of your frame, which is amazing. Granted. I only have about 8 of prints the size of 24x16 around my house and most where taken with either my 7D or 5DIII.

I also have to say, I am appreciating the M6 II more and more, which is why I am willing to take it as my second camera to Yellowstone. If you want pixels on target, it is hard to beat.
