Twenty elements in 14 groups (FLD glass + 3 SLD elements). Nine rounded aperture blades. The 95mm filter thread. At 1,930g the lens is heavy. Minimum focus distance of 2.8m. OS (Optical Stabilizer) — Sigma does not officially state a stop rating for the Contemporary version; reviewer testing indicates approximately 2-3 stops real-world. HSM motor.

The Contemporary designation indicates Sigma's mid-tier build quality versus the Sports variant of the same focal range: the Contemporary is lighter (1,930g vs Sports 2,860g) with less aggressive weather sealing, trading ruggedness for portability. The FLD and SLD elements provide chromatic aberration control at the 600mm telephoto end. The 95mm filter thread accepts standard large-diameter filters.
On the used market the Sigma 150-600mm f/5-6.3 DG OS HSM Contemporary is affordable as a super-telephoto zoom. Condition checks: OS engagement, HSM AF response, 95mm front element for marks, zoom ring smoothness. Available in Canon EF, Nikon F, Sigma SA, and other mount variants — confirm mount before purchase.
