Lens Review
Introduction | Sigma 24-70mm f2.8 IF EX DG HSM lens performance | Sigma 24-70mm f2.8 IF EX DG HSM versus Sony Vario-Sonnar T* 24-70mm f2.8 ZA SSM versus Tamron SP AF 28-75mm f2.8 XR Di LD Aspherical [IF] | Conclusion

Over image quality is good and both sharpness and uniformity are good when stopped down a little but the Sigma has high levels of chromatic aberration, particularly at the shorter focal lengths. Given the performance and the inclusion of an ultrasonic type AF motor, it’s fairly priced at $899, but still somewhat overshadowed by the better corrected and more accessibly priced Tamron.
