Sigma EX DG OS 150mm F2.8 HSM Macro Lens - Canon Fit
The Sigma 150mm f/2.8 EX DG OS HSM APO Macro Lens (Canon Fit) is a super compact and lightweight large aperture telephoto lens, with life-size (1:1) macro capability. Sigma APO Macro 150mm f/2.8 EX DG OS HSM, a large aperture medium telephoto macro lens which integrates Sigma’s original Optical Stabilizer function. Offering the latest optical design technology this lens remains a large aperture medium macro lens perfect for shooting the smaller things in our world that exists virtually unseen. A macro lens is one which will focus on a subject close enough to render it "life-size" on the image plane in your camera.
To keep high optical performance from infinity to close-up 1:1 macro photos without accessories, this EX DG OS 150mm F2.8 HSM lens incorporates a "Floating Internal Focusing" (FIF) system. As a result, the lens also features a non-rotating front lens group which makes it easier to work with polarizing filters. The HSM feature provides ultra quiet high-speed auto focusing as well as full-time manual focus override. Optical image stabilization (OS) allows you to use shutter speeds 4 stops slower than would be possible without OS.
With HSM (Hyper Sonic Motor) a quiet & speedy auto focus is ensured. It provides really high optical performance from infinity to 1:1 Macro. Three SLD (Special Low Dispersion) glass elements provide optimum colour correction and sharpness throughout the entire range and Super Multi-layer coating reduces flare and ghosting. It has better-quality peripheral brightness and provides sharp and high contrast images even at maximum apertures. The OS offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible. It is also compatible with Sigma APO Tele Converters. Perfectly suited for taking pictures of insects or other small creatures, but it is also the perfect focal length for facial portraits rendering the best perspective of the human face. This greater distance also allows the photographer more flexibility in lighting the subject with natural light reflectors. The optical design comprises 19 elements in 13 groups and includes three SLD (Special Low Dispersion) glass elements that correct colour shifts and ensure sharpness across the zoom range. The AF system uses Sigma's HSM ultrasonic motor technology, which moves two groups of elements to focus close enough for 1:1 reproduction.
The front element of the lens is 5.5 mm in diameter and close to the end of the barrel, making it vulnerable to dust, scratches and sticky fingers. It's surrounded by a narrow plate inset into the lens barrel. The inner edge of the barrel is threaded for 72 mm diameter filters and provides a secure mount for the lens cap, which has a pinch-fit attachment. Focusing and zooming are totally internal, which means the length of the lens remains constant and the front element doesn't rotate. The lens hood is 75 mm long and attaches easily with a bayonet fitting. It adds approximately 61 mm to the overall length of the lens, which extends about 218 mm in front of the camera body with the hood in place.
