Canon EF 16-35mm f/4L IS USM EF16-35mm f/4L IS USM Instructions - Page 2

Thank you for purchasing a Canon product. Canon's EF16-35mm f/4L IS USM is a highperformance ultra-wide angle zoom lens, for use with EOS cameras. The lens is installed with an Image Stabilizer. ●● "IS" stands for Image Stabilizer. ●● "USM" stands for Ultrasonic Motor. Features 1. Equipped with an Image Stabilizer that provides an image stabilization effect equivalent to a shutter speed 4 stops* faster (at 35 mm, when used with the EOS-1D X). This function provides optimal image stabilization depending on shooting conditions (such as shooting still subjects and following shots). 2. Use of UD and aspherical lens elements giving superior definition. 3. Using a fluorine coating on the foremost and rearmost lens surfaces allows adhered dirt to be removed more easily than before. 4. Ultrasonic motor (USM) for fast, quiet autofocus. 5. Manual focusing is available after the subject comes into focus in autofocus mode (ONE SHOT AF). 6. Circular aperture for producing beautiful softfocus images. 7. Tight seal structure ensures excellent dustproof and drip-proof performance. yy Since the front element of this lens moves when zooming, you need to attach a Canon PROTECT filter sold separately for adequate dust-and waterresistant performance. Without a filter, the lens is not dust or water resistant. * Image stabilization performance based on CIPA (Camera & Imaging Products Association) Standards. ENG-1
