Sigma loves to make huge fast tele lenses like the 500mm f/4.5 EX DG APO Autofocus Lens for Sony/Minolta A Mount (here at BHphoto). And it looks like there could be two more such lenses in 2014. According got Canonrumors Sigma will launch a new Sigma 300mm f/2.8 OS and 400mm f/2.8 OS tele prime lens in 2014. A new 500mm and 800mm zoom lens could also be announced although CR says it’s not sure about it. Yep, finally some new great tele to take sports pictures or spy your neighborhood ;)
P.S.: And a new tele lens from Tamron will be announced next week (via Photorumors).
