The situation deteriorates a bit at 130 mm where by f/2.8 the light fall-off in the frame corners amounts to 17% (-0.54 EV). This level is not high and additionally we must mention that on stopping down the lens to f/4.0 the problem disappears completely (4%).
Serious reservations you can start having about the 200 mm focal length. If on a small D200 sensor the brightness loss is 29% (-0.99 EV) what will happen on full frame? The fact that by f/4.0 the vignetting decreases to the level of 12% and by f/5.6 – to 4% can be considered a bit of consolation here.
After attaching the converter the situation improves a bit. By f/4.0 the light fall-off in the frame corners amounts to 20% (-0.64 EV) and the problem disappears completely by f/5.6 where the vignetting is only 3%.
You can express some reservations about the 200 mm performance. The EF 70-200 f/2.8 IS and the Sigma 70-200 f/2.8 lenses on a bit smaller Canon’s 20D sensor showed an identical value of 23%. Also the Nikkor 80-200 mm fared better here with the worst result reaching 21%.
