Canon EF 135mm f/2L USM Lens for Canon SLR Cameras
The fastest 135mm telephoto lens in its class, the Canon EF 135mm f/2L lens is ideal for indoor sports photography and portraits with background blur. Although the lens offers complete automatic focusing capabilities thanks to its Ultra Sonic Motor (USM), you can still take advantage of its manual focus function even when the camera is in AF mode. The lens also offers two UD glass elements that help minimize chromatic aberrations, giving your images outstanding sharpness and color. Other details include a 3-foot close focusing distance, an 18-degree diagonal angle of view, and a 72mm filter size. The lens--which is compatible with EF 1.4x II and 2x II extenders--carries a one-year warranty.SpecificationsFocal length: 135mmMaximum aperture: f/2.0Lens construction: 10 elements in 8 groupsAngle of view: 18 degreesClosest focusing distance: 3 feetFocus adjustment: Rear focusing system with USMMount: CanonFilter size: 72mmDimensions: 3.2 inches in diameter and 4.4 inches longWeight: 1.7 poundsWarranty: 1 year
