While I can't really argue regarding the designs, I have strong doubts that the manufacturing process can follow at the moment.
Some of the Tamron super zoom lenses have very decent results actually but it always felt as if the alignment of the elements are more of a limiting factor than the design itself. While the quality and the wide end is often fine (QC-wise), the evenness of the results (across the frame) tends to fall apart beyond 135mm here. Honestly I have a hard time to believe that such lenses are resilient enough to survive medium use over a few years (but then who cares anyway).
