Quote:The lineup is getting mature, indeed. Let's see the quality...I'm not sure there's much sense in making dedicated supertelephotos when there's so much adaptable fare. Unless Sony directly ports one of their designs to the E mount by extending it and changing the motor (to date, I think, there haven't been any examples of that). The Sony user base has a few more sources their users can rely on, and they know this (Sony A, Canon EF). So this is not the case of a lens being totally unavailable within the system. I'm pretty sure that those who need a supertelephoto lens know (and use) their options already.
"Any more ideas?"
Longer teles! M43 and Fuji now have them.
For instance, in competition to Tamron/Sigma 150-600mm f/5-* and Nikkor 200-500mm/f5.6. Also a 300mm/f4 prime would be fine.
But maybe I'm wrong and a 100-400 lens is just around the corner.
