To get the same reach from a 5D2 you have to crop it to 8mp
If you crop a 7D image to 9mp you have to crop the 5D2 to 4mp
Can 4mp be sharper than 9 mp, i don't know maybe if the per pixel sharpnes is much better. Would be interesting then I could do everything with one camera and do not need a crop camera for birding.
I use and love both cameras but the increased noise of the 7D makes large crops far less appealing than doing the same on the 5D2.
yes but you forget that he is talking about when distance limited and the bird will still get project to the same sized area on either sensor but since the 7D sensor it a trace more sensitive per area when you compare the result fairly, on a normalized basis, the 7D bird actually has a trace LESS noise
sure if you want to make use of the extra detail then you may have to deal with more noise and at some point the noise will mask any extra detail or much or it or may be too objectionable, but that still doesn't make the 7D worse, it still always does at least as well or better (it can always be made to do it with a trace less noise and less demoasic artifacts and it can often be made to do it instead with a bit more noise but more detail)
of course this is distance limited only, frame the subject the same way on both and 5D2 wins
and yeah a given level of crop is more satisfying from a 5D2 but that forgets that when you needed to crop you were probably distance limited so you won't need to crop the 7D as much and it actually wins, in the end, for total detail after cropping
I was speaking from my personal experience shooting landscape and travel images. I'm sure you can find many situations where the 7D's special characteristics will prove an advantage over other cameras (that's why I use both). Nevertheless, 5D2 files rarely need NR whereas I use NR on nearly every 7D file, even fairly low ISO. Doesn't mean I don't ultimately get great results from both cameras, but the 7D makes me work a lot harder in PP adjusting both color and noise.
