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
Tokina AT-X M-100 AF PRO 100mm f2.8 Vs Nikon AF-S Micro-Nikkor 105mm f/2.8G IF-ED Vs Sigma 105mm f2.8 EX DG OS Macro mounted on Nikon D800: Superior sharpness when stopped down
As the most modern of three designs compared the Tokina performs very well, almost matching the Nikon AF-S VR Micro-Nikkor 105mm f2.8G IF-ED, and just ahead of the highly regarded stabilized Sigma 105mm f2.8 EX DG OS HSM. The Nikon is sharper at full aperture and it has superior corner sharpness but the Tokina is sharper when stopped down which is more practical in a macro lens like this. Vignetting is much lower on the Tokina than the other two but distortion and CA are similar.
