|Sigma 200-500mm f/2.8 EX DG APO lens|
It appears Super Zoom is the new rage for zoom lens going into 2016. Egami, the Japanese photography blog has uncovered a Sigma patent for a 120-600mm f/5-6.3 lens.
Sigma and Tamron already has a 150-600mm f/5-6.3 and shorter super zoom lenses on the market and Nikon has their 200-500mm f/5.6 ED VR lens. Canon has recently patented the EF 200-600mm f/4.5-5.6L IS and EF 24-300mm f/3.5-5.6 lens.
It all started with the Canon EF 28-300mm f/3.5-5.6L IS Super Zoom lens back in 2004. This is my favorite professional grade 'L' super zoom lens for wildlife photography when it is not practical to change lens in the middle of a photo shoot. However, the lens is aging and can benefit from an upgrade. Since the introduction of the unrivaled EF 200-400mm f/4L IS USM Extender 1.4x lens back in 2013, there is room for a longer focal length Super Zoom lens in the EF lineup.
