Opteka 420-800mm 420-1600mm
Its extreme 420-1600mm zoom range and lightweight 520g all-metal body provide unmatched reach in a portable package for Canon EF shooters. The high-index, low-dispersion multi-coated glass and included 2x teleconverter deliver this focal length at a fraction of the cost of first-party super-telephotos. This lens is best for budget-conscious wildlife observers and astrophotography hobbyists who can work with manual focus and a dim f/8.3-16 aperture on a tripod.
