Duplicate Sigma 150mm macro for Nikon — same OS APO version as ID 4632.
The Sigma 150mm f/2.8 EX DG OS APO Macro is a fast macro prime from Sigma's EX line with Optical Stabilizer (OS) for Nikon F full-frame bodies. This appears closely related to id=4632, with component order in the designation rearranged — compare the two to confirm if they are the same product or distinct variants.
The lens delivers 150mm at f/2.8 with 1:1 macro capability, APO apochromatic glass, OS stabilisation for handheld macro work, DG full-frame coverage, and Nikon F coupling. Whether this version includes HSM autofocus should be confirmed from physical markings.
The 150mm focal length macro provides excellent working distance at 1:1, OS stabilisation is practically valuable for handheld macro photography, and the f/2.8 aperture serves portrait work alongside macro use.
Verify from physical markings whether this is the HSM or non-HSM version of the Sigma 150mm f/2.8 macro. Compare against id=4632 (Sigma 150mm f/2.8 EX APO DG OS HSM Macro) — these may be the same lens with rearranged canonical_name components.
