Both Versions of Sigma's 150-600mm f/5-6.3 DG OS HSM Now Available for Pre-Order

Sigma's hot, new sports telephoto-zoom lens is now available for pre-order in both of its configurations, the Sport and Contemporary models. The Sport model features superior image quality along with increased weight and a heftier price tag. It comes in Nikon F, Canon EF, and Sigma SA mount options for $1,999. The Contemporary Nikon F, Canon EF, and Sigma SA options accompany a more compact size along with fewer lens elements, only one FLD coating (as opposed to two), and a couple other "sacrifices" for a very reasonable $1,089.

Apart from the different optical designs, the two lenses are quite similar in features and even in aesthetic. Both come with the HSM (fast, quiet focusing motor), weather sealing, an f/22 minimum aperture, fairly close focusing distances (8.5 feet for the Sport, 9.2 feet for the Contemporary), and are compatible with the Sigma USB Dock. Finally, since both are part of Sigma's Global Vision line, they're eligible for Sigma's mount conversion service should you want to keep your lenses, but switch to another system.

The Contemporary models should ship March 20, 2015, while it's still unclear when the Sport models will ship. It's safe to say, however, that it won't be all that much later if not at the same time.
