8. Vignetting

At the sensor of 1.5x focal factor vignetting should be no problems for us. At 70 mm focal length we don’t need to bother at all, as there at f/2.8 the light falloff in the corners of the frame equals only 10% (-0.31 EV), and at f/4.0 falls to 2%.

It’s similar at 135 mm. At the maximum aperture vignetting reaches only 14% (-0.43 EV) and falls to 3% at f/4.0.

The biggest chance of seeing vignetting we have at 200 mm focal length and the maximum aperture, where the light falloff in the corners equals 24% (-0.84 EV). The problem vanishes completely at f/4.0 where the measured value of vignetting equaled 10%.

Situation improves again after mounting the converter. In the case of working with it, at the maximum aperture, we have vignetting of 13% (-0.41 EV), which vanishes at f/5.6 (3%).

In this category we think we have a small improvement over the predecessor. The values themselves are the same or slightly smaller with the successor, but if we take into consideration the fact that the version II was tested on a sensor of slightly larger dimensions, we can see slight improvement.
