he Sigma 60-600mm f/4.5-6.3 DG OS HSM Sports gives serious super-tele reach coupled withFLD (‘Fluorite’ Low Dispersion) elements and one SLD (Special Low Dispersion) element. Fluorine coatings are applied to the front and rear elements, to repel water and grease, and the lens is extensively weather-sealed. Handling exotica is the same as in the Sigma 150-600mm Sports lens on test. Image quality and all-round performance are excellent, although sharpness drops off a bit at the long end of the zoom range.
