"In terms of image quality, I was pleasantly surprised by the optical performance of this glass. The sharpness in the center is very good even at the widest settings, while the corner resolution improves significantly at f/5.6. Have a little bit of Vignetting and chromatic aberration at f/4 but they also decrease when stopping down the aperture." Read full review
