Test_30mm_f/1.4_SDIMa_12538

Sigma 30mm, f/1.4 in this shot. I applied no sharpening. As you can see even at f/1.4 the lens is reasonably sharp and contrasty, even in the corners. In the center is quite sharp, so much that aliasing is visible in some places. A bit of vignetting is visible, which is normal in a f/1.4 lens anyway. There is some overexposure in the central area since 1/4000s was not enought at f/1.4 with so much light.
