Sigma 24-70mm f/2.8 EX DG HSM

Great lens. Unbelievable fast focusing. A lot faster than the Nikon 28-70 2.8. Sharper than the Nikon 28-70 2.8 at 28mm, comparible at 70mm. IQ is great. Using a Nikon D300 gave no problems or whatsoever in close up range as reported by others. All in all a very impressive lens !
