Here's a little test I just ran with the lens I own that gives the most vignetting on an FX body, the AF 14mm f2.8D
Both photos were taken handheld from the same location with my D700 and the 14mm at f2.8. Both photos were shot in raw but the 1st photo has the D700 vignetting control off, the 2nd photo had the D700 vignetting control high. Both photos were viewed and saved in CNX2 with no post processing other than what is built into CNX2 which reads the D700 data and adjusts accordingly. CS3 was only used to resize the photos.
By the way the leaning trees on the left are a result of hurricane Sandy and not lens distortion. The tree guy is coming in next week to clean up.
edit: More info. I just adjusted the vignette correction in CNX2 on the 1st photo and adjusting the slider all the way to 200 the result was the photo looked just about identical to photo 2.
Also in-camera vignette correction does not work with a manual non-CPU lens even if the data is entered in the non-CPU menu. I tried it using the AIS 15mm f3.5 lens. No difference in CNX2.
