I don't see how you read that, going by your initial post.
You referred to your downward spiral in upgrading bodies, but you already have top class lenses.
The summary of this thread is: for those newbies that have found approximately $1.5-2K spare moola, and can't decide whether to upgrade their camera, or purchase a new lens.. that the vast majority of replies will be simple
"upgrade your lens, because the lens last a lifetime, whereas better bodies go and come every couple of years"
And then you made a statement of fact with the implication that all Canon lenses work equally well on all Canon bodies, but the results from DxO seem to indicate the opposite is true as with every brand. The brand was irrelevant, and I only chose Nikon because that's what I'm familiar with and have any real interest in.
Despite what the user thinks they see in their equipment(which is generally jaded by having made the investment with their own money), a scientific set of data is really the only way with which to properly judge the relative performance of each lens-camera setup.
That is, a slightly lesser quality lens(consumer grade) can produce better detail on a higher res body if resolution is a paramount requirement!
Your, or my, subjective opinion doesn't mean a thing if the data can't be quantified without any prejudice... which we'll all have to a degree, if we don't analyze the results in a scientific manner.
While your requirements may not be such that lp/mm differences are going to make any difference to a 300DPI print, your actions don't seem to reflect that philosophical stance either.
You know you can only really get 11-12lp/mm in a 300DPI print, yet all your lenses far exceed that capability... and you still set yourself on a downward path of upgrading camera bodies as well.
So it poses other questions ...
1. if you can't see any difference in those lp/mm figures in a 300DPI print, why waste money on better equipment?
2. is a 300DPI print the final say on what it is we want from our equipment?
3. has technology suddenly stopped progressing for some reason and that in the future better printing technologies will not become available?
if that is the case(in #3) how do the
high res chart creating folk produce prints that can resolve up to 400lp/mm.. that seem to cost a small fortune to purchase?
as for pixel information sharpness issues with hi res sensors, that's a user/operator induced variable.. not one that can be blamed on the sensor itself.
The best way to get more information from every detailed part of a scene is to have more pixels, sometimes even if that means smaller pixels, as long as noise(SNR) doesn't interfere with the sensor data.
My post came about as a result of having read some discussions(elsewhere) as to the value of
hotrodding a camera by removing the AA filter!
The camera in question pertained to no less than a D3x! the owner wanted more detail/sharpness, and the end result of the discussion is that if you want more detail/sharpness from each detail in the scene, you simply need more pixels... in this case that means moving up to MF, as 35mm DSLR technology has maxed out at the moment at 25Mp. Due to inherent problems and the psuedo increase in detail/information levels it was suggested that the owner not hotrod his D3x(or any camera).. MF was the only real way forward for now.
at the risk of running another gauntlet of scorn!
I'll produce one more quote with a simple question:
In what way are they misleading? Are you saying that their results are bogus, that a kit lens on a hi res body doesn't produce more detail, or apparent sharpness than a pro lens on a lower res body?
or are you implying that my opinion that having a more feature rich body with better ability(eg. better focusing/faster fps/cleaner high ISO/etc won't produce better images either).
I apologise if my posts are long a tedious, and I do warn folks about that issue, but the context and implications are 100% set and there is no (usually)ambiguity, and that requires detailed explanations.
A small quip, then taken and turned into a quote is a simple quote.
I've read and reread your initial post a few times now, and I really can't see how I've misrepresented what you said... maybe you also need to take more time to explain in detail what you really meant then?
I did read(in your first line of your first reply) a large amount of contradictory opinion.
First you say that a Canon lens works equally well on
ANY body whether a low end consumer body, or whether it's a top flight uber pro body... that there is no demarcation from one body to the next in terms of IQ. Then you say get the best(body??) to get the best out of your lenses?.. whatever your experiences you have that dictate your opinion is fine by me.. but it seems that my experiences are slight the same, even if they are slightly different too.
My humble opinion, and limited experience, with having used various bodies is that you can get a much better image result in many cases by upgrading the body first, as long as the (consumer grade)lens is of semi decent quality to begin with.
