Sigma's budget telephoto zoom with macro capability, available in many mounts.
The Sigma 70-300mm f/4-5.6 DG Macro is a consumer telephoto zoom from Sigma's DG (full-frame compatible) range, available in Canon, Nikon, Sony, and several other mounts. The DG designation indicates full-frame image circle coverage, making it usable on both full-frame and APS-C bodies. A macro mode at the 300mm end enables closer focus distances than the standard minimum, providing approximately 1:2 magnification for moderate close-up work alongside the primary telephoto function.
The optical design uses 16 elements in 11 groups. The 58mm filter thread is shared with several Nikon DX kit lenses, enabling filter carry-over within a standard Nikon DX two-lens setup. At approximately 545g the lens is moderate in weight for a 300mm zoom. The macro mode at 300mm enables focus at approximately 0.95m for close subjects at telephoto distance. Autofocus uses a conventional DC motor — functional for general stills use but audible during operation and not suited for video recording. Variable aperture runs from f/4 at 70mm to f/5.6 at 300mm. Build is lightweight plastic with no weather sealing.
For standard outdoor telephoto use the 70-300mm DG Macro covers wildlife, sports, and travel subjects at an accessible price. The macro capability at 300mm extends the lens's practical range to moderate close-up work — insects, small wildlife, and detail photography — though the 0.95m minimum focus at 300mm is not a substitute for a dedicated macro lens. On APS-C bodies the 105-450mm equivalent provides substantial reach. DC motor AF is reliable for stills; the audible operation rules out video use.
On the used market the Sigma 70-300mm DG Macro is widely available at very low prices. Condition checks: DC motor AF response at both ends of the zoom range, macro mode engagement and release, and zoom ring smoothness. The lens is available in multiple mounts; confirm the mount version matches the target body. Sigma's HSM (Hypersonic Motor) 70-300mm APO DG provides faster, quieter AF at a modest premium and is the recommended upgrade for demanding stills use or video.
