Sigma 10mm f/2.8 EX DC HSM Fisheye Lens for Canon Digital SLR Cameras
Designed for use with Canon digital SLR cameras equipped with APS-C size image sensors, the Sigma 10mm f/2.8 fisheye lens offers a uniquely exaggerated and distorted close-up perspective that's perfect for arty, off-kilter shots. This Canon version offers an impressive 167-degree diagonal angle of view, along with a minimum focusing distance of 5.3 inches and a maximum magnification ratio of 1:3.3. As a result, subjects can sit as close as 0.7 inches from the lens's front element, making the lens ideal for extreme close-up shots and photos with a large depth of field. The lens also includes a Hyper Sonic Motor (HSM) that provides fast and quiet autofocusing, with a full-time manual focus override via a simple twist of the focus ring. And thanks to the lens's integral hood and super multilayer coating, you can easily block out extraneous light while minimizing flare and ghosting. Supplied with a gelatin filter holder at the rear, the 10mm lens carries Sigma's one-year warranty.SpecificationsFocal length: 10mmMaximum aperture: f/2.8Lens construction: 12 elements in 7 groupsAngle of view: 167 degreesNumber of diaphragm blades: 7Minimum aperture: f/22Minimum focusing distance: 5.3 inchesMaximum magnification: 1:3.3Filter type: Insertion-type gelatin filterMount: CanonDimensions: 3 inches in diameter and 3.3 inches longWeight: 16.8 ouncesWarranty: 1 year
