Tokina AT-X M100 AF Pro D 100mm f2.8 Nikon mount lens review: Excellent all-round performanceBy Kevin Carter - Tuesday December 10 2013 Lens Review
The Tokina achieves a DxOMark lens score of 31 points on the 36-Mpix D800, and has a high sharpness score of 19P-Mpix. At full aperture the Tokina has good sharpness in the center, which expands across the frame stopping down only one stop to f4. Peak sharpness is achieved at f/8.0 but it still has high sharpness levels at f/11 on the D800. It also has very low levels of vignetting at full aperture, which has nearly disappeared by f4 and has gone completely by f5.6. Distortion and CA are also well controlled for a lens like this.
