The Sigma APO 180mm F3.5 EX DG lens is a telephoto/macro lens produced by Sigma Corporation. It contains two SLD (Special Low Dispersion) glass elements to provide correction for chromatic aberration. It is aimed toward advanced consumers
Designed for use on full frame digital SLR cameras, but can also be fitted to DSLRs with smaller APS-C size sensors, where it covers a similar field of view to a 270mm lens when fitted to Nikon, Pentax and Sony cameras with 1.5x crop factors or 288mm with Canon DSLRs. It appears to have been replaced by the 150mm F2.8 EX DG HSM Macro lens.
The 180mm macro lens has the EX (‘Excellence’) matte finish on the lens barrel and supplied cylindrical hood and comes with the same DG (‘digital’) coatings that minimise the effects of internal reflections off the surface of the sensor. It’s significantly larger than the 105mm lens and has some features that lens lacks.
This lens come with a 90 mm long cylindrical lens hood attaches with a bayonet mount on the front of the barrel. It can be reversed over the barrel for storage or carrying. You can also fit the lens cap when the hood is in either position.
Also supplied with the lens is a removable tripod collar with a screw nut that enables the camera body to be rotated between horizontal and vertical positions without requiring the lens to be detached from the tripod.
