8. Vignetting

Of course one of the basic differences between the A100 and A900 results, which we expect to find, is the vignetting level, arising from the different size of the used detectors. Let’s start with the APS-C/DX matrix from the A100.

In this case, the vignetting is visible only at maximum aperture, with the level of 24% (-0.80 EV). The result is good, especially taking into account the lens’s good parameters and the fact that, on stopping down to f/2.0 vignetting decreases to 11% so it becomes practically imperceptible.

The problems will be more serious on full frame. While working at maximum relative aperture we get a corner illumination loss of about 59% (-2.6 EV). This time the problem won’t be solved easily - even by stopping down by one stop because, after that procedure the vignetting still is at the high level of 43% .By f/2.8 the illumination loss still reaches 23%. Only near f/4-5.6 the vignetting decreases to the level of 15-11% so stops being a nuisance in the real photos.
