of the tested lenses on a Canon 5D2 |
The centre value in every vignetting sample image shown below is exactly the same. Any vignetting
appears as a darkening of the images from the centre towards the edges.

Test Conditions
Lenses where focused at infinity, on a tripod with identical test
conditions.
No UV or protective filters where used.
Shot on a Canon 5D2 at ISO100 in RAW then converted to sRGB jpegs in Phase One Capture One.
Vignetting correction was disabled during RAW conversion.
The centre of every exposure is identical as each image was adjusted to
128 R/G/B during RAW conversion then fully desaturated.
