This looks like a tempting, albeit more expensive, replacement for Sony's meh 28-70mm f3.5-5.6 full-frame kit lens.
The company updates its 3-year-old lens in almost every way.
Adding to its new line of fast lenses, Tamron introduces an 85mm f1.8 and an updated 90mm f2.8 macro, as well as a Sigma-like adapter for configuring them.
The company adds two new fast telephoto lenses to its SP lineup.
Tamron's first non-macro primes, a 35mm f1.8 and 45mm f1.8, look promising and serve to launch a new generation of lenses.
Taking a leaf out of Sigma's book, Tamron's first standard primes have metal bodies and an upscale feel. All but one of the product shots were taken with one of these two lenses.
