On second thought I think the Tamron's designers are a bit very close to Sigma's design rules, even the shiny plate indicating Art, Contemporary and Sports had to be imitated. On a shop shelf at remote distance and not seing the ring at the mount, both manufacturer's products could get confused. I wonder why Tamron didn't do more to make their's different?
What I like is the close minimum distance. Even if the lenses would not perform top peak at close distance, it's sometimes good to have a "nearly macro" aboard.
