Sigma never disappoints the expectation of the users. It has always kept introducing the brand-new and the most advanced technology in its new products. Unique and innovative technology in its new products often surprises even the professional photographers. Therefore, although I had basically used the lenses of the camera makufacturers, recently I can’t take my eyes off from Sigma lenses. Sometimes in the future, using the camera body of camera manufacturer with the unique Sigma lenses might be a status symbol of the professional photographers.

Sports photographers normally use two lenses, the 70-200 mm tele zoom lens and the 300 mm fixed tele lens. This is the typical equipment for the sports photographers. They chase the subjects and try to capture the decisive moment by exchanging two lenses. However, under this circumstance, even experienced professional photographers might miss capturing such a moment. That’s because the focal length between 200-300mm is not covered by these two lenses. Many photographers have missed the “best shot” just because they use the 70-200mm lens by accident at such a moment, not the lens that covers 300mm. Therefore, the introduction of the 120-300mm telephoto zoom lens with large aperture F2.8 from Sigma has excited many photographers so much because it’ s a just ideal lens for them. In addition, this lens has another allure. It adopts four Special Low Dispersion (SLD) glasses so as to compensate color aberration. Moreover, Hyper Sonic Motor (HSM) is equipped in order to realize the quiet and fast focusing. I have been always impressed by the image quality provided by this lens, which might have surpassed fixed focal length lens. If I were allowed to say one comment on this lens, I would say that it would be nice if the zoom torque could be slightly lighter.
