Canon 70-200mm f/4L IS Lens Review at The-Digital-Picture
The-Digital-Picture have reviewed the new Canon EF 70-200mm f/4L IS USM lens, which offers up to 4 stops of image stabilisation with 2 modes and a compact, lightweight body.
“Canon’s first 4-stop Image Stabilizer makes this lens just as handholdable in low light as the extremely popular 70-200 f/2.8 IS with its 3-stop stabilizer and wider aperture. You can shoot with this lens hand held at an up-to-4-stop slower shutter speed than with the non-IS Canon 70-200mm f/4 L USM Lens. For example (and theoretically), if you need a shutter speed of 1/250 at 200mm without IS to achieve sharp images, you can shoot at 1/15 with the 70-200 f/4 IS with similar results - this is a huge difference. The image stabilizer will compensate for camera movement during the shot (within limits of course).”
