Filed under: Uncategorized — admin @ 2:19 am

The Canon EF 1200mm 5.6L lens is a professional EF lens made by Canon that was introduced in 1993, six years after the launch of EOS cameras, and discontinued in 2005. The initial price for this lens was US$89,579. It weighs more than 36 pounds (16 kg), comes with its own heavy-duty tripod and case, and was built only by request. The focal length can be increased to 1700 mm or 2400 mm 11 using the Canon EF Extenders 1.4× and 2× respectively. Few of these lenses exist; Sports Illustrated magazine owns two of them, as does Canon Professional Services and James Jannard, the billionaire founder of Oakley.
