Wow! You guys are way over my head.:grin::salute:
In my world, language is sometimes not sufficient to talk about what is "sufficient". That is not a pun, it is reality. For me, as irrelevant in this world as I am, I try to avoid discussions that require defining every word and explaining the context of everything about human perception and even "objective" evaluations. But, I must say that there are differences in files from the D850 vs. H5D-50c vs. Leica S vs. Phase One, and I see it all the time. I find the D850 to be frustrating as I feel it could be so much better but it falls short based on my eye and preferences. The 50c and the S are very close in rendering and providing "satisfaction" to me in personal perception as well as the experience of using them. And yes, they are three different systems with different specs.
Phase One is the pinnacle from my POV. I cannot afford it and have no need because I am not a commercial photographer. I am just a guy who uses Photography as a means of expression and sometimes to do a pro bono project.
"Sufficient" to me is different than anyone else on this forum and probably anyone else. It is curious to me why the debate is always on, I thought we passed that years ago when those who knew much more than me stated that 24 MP was all we would ever need and maybe even film would be all that we need. Clearly all of those statements were not exactly correct and even now, I do not think 150 MP or even the 14/16 bit arguments about sufficiency or desirability will stand.
So, I find my enjoyment in older systems as well as the images I see from P1 150 MP images and everything else in between. I absolutely agree with what Steve said about maximizing your results if that is a requirement/desire of the photographer, and his/her decisions make all the difference. After all, the photographer is the most important spec in my opinion. And if one makes a living with the images, competing in a tough market, then maximizing results is a huge priority... not being "good enough" which is all too common in my world.
That is really all I have to share and it is just my own personal viewpoint. Take it with you if you want, or better yet, take a camera and enjoy the world outside of the forum, using whatever you like. I am sure your work will be grand and I would love to see it.:thumbup:
