The EF300mm f/4L IS USM is a compact and lightweight 300mm super-telephoto lens with Image Stabilizer (IS), similar to EF 75-300mm f/4-5.6 IS USM. The Image Stabilizer shifts a lens group (11th to 13th elements) in parallel to the film plane. Camera shake is a major cause of blurred images especially with telephoto lenses. The IS system helps resolving this problem. The image stabilizing effect is equivalent to about two steps of shutter speed. "IS Mode 2" is newly applied to stabilize finder images at panning shots of moving subjects. The optical system uses two UD (Ultra-low Dispersion) glass lens elements (2nd and 5th) to compensate secondary spectrum and provide sharp, high-contrast images from maximum aperture.| Product Description | Canon EF telephoto lens - 300 mm | | Lens System | Telephoto lens | | Intended For | 35mm SLR, digital SLR | | Mounting Type | Canon EF | | Lens Aperture | F/4.0 | | Focal Length | 300 mm | | Min Focus Range | 1.5 mm | | Focus Adjustment | Automatic, manual | | Lens Construction | 11 group(s) / 15 element(s) | | Special Functions | Tele | | Length | 22.1 cm | | Weight | 1.2 kg |
