It appears that Sigma will enjoy us with more lenses based on their new technology. Various lenses that will be part of the “Sport” line-up may be announced. The rumor fits with the rumored list of next Sigma lenses we posted aome time ago.
The rumor has word that Sigma will announce first a 300mm f/2.8 OS and a 400mm f/2.8 OS lens. These lenses may be undergone field-testing during the Winter Olympic Games. The other lenses Sigma is said to work on are a 500mm and a 800mm lens.
