Is there different test method to measure the vignetting for a lens? Because I've check on other site lens review and they seem to end up with almost twice the vignetting value compared to here.
This time I did some research just to be sure I'm not asking for something stupid... I hope I did not forget something.
There are a lot of example but I'll cote only this one,
Nikkor AF-S 50mm f/1.4 Ghere it get a vignetting value of .56 Ev
On the other site the have a value of 1.00 Ev
They are both shot with a Nikon D200
Most lens have a noticable difference, some like the Micro 40 mm , have almost the same value.
Is there a reason for that?
