“But what about the Tamron 17-28mm f2.8?” I asked our rep over at Tamron. Apparently, the Tamron 20-40mm f2.8 Di III VXD lens isn’t replacing the older optic. Instead, they’re kind of, sort of, complementary to one another. At that moment, My head cocked to the side like a confused dog staring at you trying to understand what you’re saying. Except in this case, I stared in bewilderment at my computer screen. The Tamron 20-40mm f2.8 indeed doesn’t replace the Tamron 17-28mm f2.8. But for all accounts and purposes, it probably should.
