8. Vignetting

For the users of APS-C/DX class sensors the vignetting problem doesn’t exist in the case of the Sigma 2.8/105. Even at the maximum aperture the light fall-off in the corners is just 16% (-0.5 aperture value). On stopping down to f/4.0 the problem is simply marginal as it reaches just 4%.

It is worth emphasizing, though, that on a 35 mm detector the vignetting will be higher but it might become bothersome only by f/2.8.
