Sigma's extreme DX superzoom for Nikon — the 18-300mm covering 27-450mm equivalent.
The Sigma 18-300mm f/3.5-6.3 DC Macro OS HSM Contemporary is Sigma's extreme superzoom for Nikon F-mount APS-C DSLRs. Covering a 27-450mm equivalent range with optical stabilisation and HSM motor, it competes directly with the Nikon 18-300mm VR and Tamron 16-300mm VC. The Contemporary designation indicates a compact design optimised for portability.
Optical performance is typical of extreme superzooms — decent at moderate focal lengths with softening at the extremes. OS stabilisation is effective at longer focal lengths where the slow aperture demands steadier hands. HSM motor provides fast, quiet autofocus. The macro mode allows closer focusing than standard zooms. Centre sharpness is respectable throughout.
Nikon F mount, DX format. Filter thread is 72mm. Weight is approximately 585 grams — compact for the range. Build quality is good with the Contemporary designation indicating quality materials. The lens includes a zoom lock switch. No weather sealing. OS and HSM are significant features that elevate this above budget superzooms.
Available on the used market at reasonable prices. Check OS motor, zoom creep, and AF function. The OS and HSM features make this more refined than budget alternatives. A solid one-lens travel solution for Nikon DX shooters. The Contemporary build quality is notably better than earlier Sigma superzooms.
