SIGMA 105mm Macro for Canon SLR

The SIGMA 105mm F2.8 EX DG OS HSM Macro Lens is built for Canon EOS DSLR cameras. It suits photographers who need true 1:1 magnification for close-up subjects. The lens covers full-frame sensors and works on APS-C bodies with an effective focal length near 150mm. It is not for shooters who require autofocus on mirrorless mounts without an adapter.

Optical Stabilizer and focus limits

The OS system allows handheld shooting at close distances where camera shake is magnified. A floating focus system corrects aberrations from infinity down to 1:1 macro. Minimum focus distance is 12.3 inches at maximum magnification. The design does not suit users who need internal focusing that keeps the front element stationary.

62mm filter thread and splash-proof build

A 62mm filter size fits standard circular polarisers and protective glass. The barrel includes a splash-proof construction for damp or dusty environments. Nine rounded diaphragm blades produce smooth background blur at wide apertures. Buyers who need a different thread diameter or weather-sealed mount gasket should look elsewhere.

Questions about this item

Should I choose the 105mm f/2.8 macro or a longer focal length for full-frame close-ups?

On full-frame the 105mm f/2.8 gives 1:1 magnification at 12.3 inches working distance; on APS-C the field of view equals about 150mm, so you gain reach without changing lenses.

What does the f/2.8 aperture deliver when I am shooting at 1:1 macro distance?

At 1:1 the effective aperture drops to about f/5.6, so you lose two stops of light but still keep a bright viewfinder and the rounded 9-blade diaphragm for smooth background blur.

The lens uses a Canon EF mount — does that limit me to DSLR bodies only?

The EF mount fits every Canon EOS DSLR directly; for EOS R mirrorless bodies you need Canon's EF-EOS R adapter, which retains autofocus, stabilization and full-time manual focus.
