EF 300mm f/4L IS USM
This is without question the first place to look in the EF lens line-up for a long telephoto lens when portability and great hand-holding ease are your priorities. Far lighter than a 300mm f/2.8 lens, this L-series lens gives excellent image quality and sharpness, along with superb close-focus capabilities and excellent "reach". Its super-smooth manual focus ring allows easy fine adjustments (even in the lens's AF mode), and offers HD video shooters easy "focus pull" when it's mounted to a tripod or a shooting rig.
- Great lens for any still-image shooting calling for hand-holding, especially with rapidly moving subjects (air shows, sports, birds in flight, etc.)
- Focuses down to 4.9 feet (1.5m) – 0.24x magnification (nearly 1/4 life-size; with full-frame camera, can fill the frame with a subject the size of a postcard)
- Image Stabilization minimizes effects of camera shake and allowing shooting at shutter speeds up to two stops slower than would otherwise be possible
- Compatible with all Canon EF 1.4x and 2x tele extenders; full AF on any EOS body when used with the 1.4x extenders (with 2x, AF at Center AF point, with EOS bodies having 45-point AF; possible with 61-point AF cameras after firmware upgrade)
