Introduced to replace the EF 200mm F1.8L USM which was announced in 1988, the new Canon EF 200mm F2L IS USM has a smaller aperture but is embedded with Image Stabilization (IS) which is able to give up to 4 stops of image stabilization. In this test, sharp image was achieved at the setting of 1/8s, an extra stop as compared to the 4 stop Canon announced. Common rule for minimum shutter speed is 1/focal length, 1/200s in our Canon EOS 5D test. Read the whole test & see test photos here.
