My previous post on this generated many response/questions/issues etc. Some of which were not really relevant to my original post. If that is due to my brevity or lack of explanation or testing procedure then I apologise.
Here is the rationale of this comparison:
My longest lens is a 300mm f/4L IS.
I have access to a 5D2 and a 7D.
I want to know what \"reach\" or image quality the 5D2 can give me compared to the 7D with my longest lens, in a real world example.
I will not be changing focal length.
I will not be moving toward or away from the subject.
I will not be shooting charts or different ISOs/apertures.
This comparison is for those photographers who are interested in how the FF 5D2 compares with the crop 7D when you can\'t move or change lenses.
To get the subject sizes the same (and again, without changing lenses/focal length or foot zooming!) The 5D2 image needs to be increased 150%
The shots were @300mm, f/4, 1/4000s, ISO400, tripod, 10x live view manually focused on the same point, processed exactly the same in DPP with no NR and with Sharpening 1.
Here is the scene as seen by each camera:
7D:
5D2:
Here is a 100% crop of the 7D image:
Here is a 100% crop of the 5D2 image increased 150%
