Samyang brought autofocus into their range of lenses not too long ago with two new Sony E mount lenses. The 14mm f/2.8 and 50mm f/1.4. Now, in a recent interview with Focus Numerique, Samyang head of product planning, Jeong Min Shin says that more are to come.
In the interview, he talked about some of the decisions and compromises that had to be made with the new Sony lenses. But he also suggested that Nikon and Canon autofocus lenses may not be too far away. The story for Fuji and micro four thirds, however, may be another matter.
