And so, at 10 mm and f/3.5 the light falloff in the corners of the frame equals 37% (-1.34 EV) which is a considerable result. At f/4.0 vignetting falls only by 2%, and at f/5.6 it’s still 29%. At f/8.0 this aberration reaches 25% and ceases to decrease with further stopping down.
It’s much better for the middle of the focal length, where at the maximum aperture of f/4.2 vignetting amounts to 20% (-0.65 EV). Stopping down to f/5.6 makes the light falloff decrease only by 3% and then stops decreasing with stopping down.
It’s very similar at 24 mm. There, at f/4.5 vignetting amounts to 17% (-0.55 EV) and decreases to a practically unnoticeable level of 12% at f/5.6.
We need to emphasize now that Tamron 10-24 comes out well comparing to its rivals. Canon 10-22 mm could show vignetting of almost 50% and lengthening of the focal length didn’t decrease the level of this aberration much. Sigma 10-20 mm, at the maximum aperture, at all focal lengths produced the light falloff larger than 30%.
