The 180mm f/2.8 is Sigma's flagship large aperture telephoto macro lens. It's the worlds first 180mm optically stabilized telephoto macro lens that offers effective correction of approximately 4 stops.
This high performance Lens features three FLD (“F” Low Dispersion) glass lenses that have a performance equal to fluorite ensure exceptional correction of axial chromatic aberration and lateral chromatic aberration. A floating inner focusing system moves two different lens groups in the optical path to different positions. This system compensates for astigmatism and distortion and provides extremely high optical performance from infinity to 1:1 macro. The overall length does not change during focusing, ensuring convenient handling. Metal parts are used in the lens barrel ensuring high durability of the body.
Optical Stabilizer (OS)
This is the first 180mm optically stabilized telephoto macro lens in the world and offers effective correction of approximately 4 stops. The system compensates for camera shake even in the macro range photography where only a small amount of blur can be easily identified.
Large Maximum Aperture of f/2.8
This is the first 180mm telephoto macro lens in the world with a reproduction ratio of 1:1 and a maximum aperture of F2.8. The narrow depth of field enables photographers to emphasize the subject and the large aperture provides a bright viewfinder image. Together with the OS function, they help the photographer confirm accurate focusing.
Flare and ghosting conscious design
In order to achieve high rendering on this flagship lens, flare and ghosting were thoroughly measured from an early stage to establish an optical design which is resistant to strong incident light such as backlight. The Super Multi-Layer Coating reduces flare and ghosting and provides sharp and high contrast images even in backlit conditions. The hood adapter extends the length of the lens hood and provides more effective shading to block out extraneous light which may have a harmful influence on the lens’s rendering performance.
Hyper Sonic Motor (HSM)
The lens incorporates HSM (Hyper Sonic Motor), ensuring high speed and quiet AF as we as full time manual focus capability.
This lens incorporates a brass made bayonet mount which has both high accuracy and durability. A special treatment to reinforce its strength is applied to the surface giving it greater strength and making it highly resistant to long-term use.
