For me, you do not need to justify how you want to use your D850.I hope this give you another idea to address your concerns...I have read most if not all of that - The size of the pixels in a sensor does not change physically When you change the settings in a camera, it is done through software, and many different "tricks are played to get the output image we see." What I am talking about is that since the size of the Physical Pixel is directly a determinant of the pixel dynamic range and therefore the image dynamic range. If the individual pixel does not have the higher DR, then the Image cannot possible have higher DR, unless it is artificially altered.....A 24Mpx Cmos (D750) sensor will have less DR than a 24Mpx BSI Cmos (A7III) you can Google the reason why...The reason why the D850 BSI Cmos pixels have less DR is because the BSI Pixels pixels in the A7III have LARGER PHYSICAL PIXELS...In addition, if the D850 has 24Mpx, processing the 24Mpx is quicker than 45.7 Mpx and therefore you can get faster FPS without the Battery Grip and a smaller lighter body (with 10 FPS - like the D500 same battery etc.)Why do you think the best Dynamic Range is found in Medium format Cameras???? BECAUSE THEY HAVE LARGER PIXELS ! - YMMVSomebody please let me know where my logic is wrong.Similar logic goes with DX (APS) vs FX (Full frame)...

The camera body, including sensor within, had nothing to do with what you perceive to be image quality in the original shot you posted. I've done nearly the same shot with a D2X (far less dynamic range) but with a similar grade lens (the 200/2G instead of the 200/2 AIS). The qualities of that shot are due to lighting, lens, and aperture choice. That's it. It really is that basic. What's more, the dynamic range of that scene is *nowhere* near the dynamic range of any current DSLR made within the last several years.You could shot that shot with a body 5 years from now with (say) an extra 2 stops of DR, and if you used a lessor quality lens, wouldn't get as good a shot. That shot is not a technically difficult challenge as it is lit, for any even remotely modern sensor. The qualities of the lens and lighting are by far, substantially so, the reason for the look of that image.This might be an entirely different discussion if the scene was something that actually pushed the edges of the DR capabilities of the cameras being discussed, but it doesn't.Frankly, unless you are making a living as a dance/theater/concert shooter working in low light exclusively, or as a sports professional working at high ISO requiring high frame rates exclusively, the modern bodies offered today are pretty amazing and more similar in terms of the potential of output quality than they are different. Photographer skill, use of excellent (as opposed to just "very good") lenses and quality of post processing will make vastly more difference than the sensor differences these days.And that is that.-m

The poster of the first post seems to think that the photo was made possible by the camera alone, so he should get that camera, because the higher pixel count of the D850 surely makes no difference for it. So if you want the better manual focus peeking of the Sony, you need to get one. If you think it takes your photography to the next level, go ahead, never look back.

I had a list of latest sensors from the Phase One sensors to most of the latest arrange by dynamic range , highest to lowest and the top 4 or 5 are all Medium formats. I am trying to locate it but have not found it yet....I will post when I find it...Somebody please let me know where my logic is wrong.Everywhere starting from the notion that it's the pixel size that determines the overall DR of the sensor.Its not the sole determinant but it is a major factor, i.e.BSI CMOS vs CMOS sensors, CCD vs CMOS, .....others. A BSI CMOS will capture more light than CMOS of the same pixel size....

Not a Nikon user at the moment, but interested in the forthcoming mirrorless, I check the forum from time to time.I don't understand, why did this silly post get so much attention?
