105mm f/2.8 Macro Lens for Nikon AF

This SIGMA macro lens delivers life-size 1:1 magnification at a minimum focus distance of 12.2 inches (31 cm). It suits photographers who need close-up detail for nature, product or portrait work on Nikon AF bodies. The optical formula includes Special Low Dispersion and high-refractive-index SLD elements to control aberrations across the full focus range.

Quiet HSM autofocus and focus limiter

The Hyper Sonic Motor provides fast, quiet autofocus with full-time manual override. A focus-free mechanical design keeps the manual ring stationary during AF operation so handling never slows the motor. A three-position focus limiter splits the broad range into nearer or farther zones to speed up acquisition in typical shooting situations.

1:1 magnification at 12.2" working distance

The defining specification is true 1:1 macro reproduction at 12.2 inches (31 cm) from the subject without accessories. Buyers who need greater magnification or a longer working distance for skittish subjects will need a different optic.

Questions about this item

How do I mount the Sigma 105mm f/2.8 EX DG OS HSM Macro Lens on my Nikon AF camera and what step do people often miss?

Align the lens mount index with the camera body index, twist clockwise until it clicks, then set the focus-mode switch to AF; the step many miss is leaving the focus limiter in the wrong range, which prevents the lens from reaching 1:1 macro at 31 cm.

What maintenance or replacement will the Sigma 105mm f/2.8 EX DG OS HSM Macro Lens need over time?

Clean the front and rear elements with a blower and microfibre cloth; the HSM motor and OS unit are sealed and not user-serviceable, so any mechanical wear requires professional repair.

What limit appears first when I shoot continuously at f/2.8 with the Sigma 105mm f/2.8 EX DG OS HSM Macro Lens?

The focus limiter range you select becomes the practical limit — if the limiter is set to the far range the lens will not focus down to 12.2 inches for 1:1 magnification until you switch it.
