|Sigma 200-500mm f/2.8 APO EX DG lens|
Zeiss is known as the third party lens maker that charges 'an arm and a leg' for those who want to own German glass. The recent announcement of the Sigma 20mm f/1.4 Art lens and their other offerings in the line in the past couple of years have many photographers sit up and take notice of this Japanese lens manufacturer. Zeiss recently introduced a 'lower priced' Milvus line of lens to try and blunt the appeal of the Sigma Art line.
Sigma will build on their recent success and continue to introduce more Art lens in 2016. This will certainly coincide with the big German trade show Photokina next year. Among the sought after Art lens will be the 85mm f/1.4, 24-70mm f/2.8 OS and the 70-200mm f/2.8 OS Sport.
All told, Sigma may be working on about 10 new Art lens, including wide angle primes and Super Telephoto models and will announce more models in the next 12 to 18 months. There is no plan to replace the Sigma 200-500mm f/2.8 lens, which is mostly a conversational piece of glass. The company that should be most worried is Zeiss.
Canon is already readying their venerable EF 70-200mm f/2.8L IS III model for a 2016 announcement. Their Series II Super Telephoto lens lineup is in good shape, except for the replacement of the EF 800mm f/5.6L IS, which may be announced some time next year. The recently featured prototype EF 600mm f/4 DO BR lens during the Canon Expo 2015 will be the most anticipated lens for me in 2016 if they decide to release it.
