Long lenses for seascapes
David uses a long Canon EF 100-400mm f/4.5-5.6l IS II USM for tighter compositions of interesting parts of a coastal scene – it’s sharp and very reliable. He also uses a EF Extender 1.4x teleconverter to multiply focal length. Using this extender, his Canon EF 100-400mm telephoto zoom becomes a whopping 560mm at the long end, with close focusing capabilities of just one metre.
