Tamron has long been known as a reliable manufacturer of high-quality lenses, and their recent series of SP lenses has more than demonstrated their commitment to excellence. Through priorities for speed, clarity, optics, and a field-friendly design, Tamron has created a fabulous workhorse lens in their new 15-30mm (Model A041). The lens replaces the previous Model A012, delivering a variety of new features that make the lens not only faster and more reliable than its predecessor, but allowing it to yield surprisingly crisp, beautiful images. I put the 15-30mm G2 to the test on my recent 17-day journey through Belize, traipsing through Mayan ruins, along wind- and salt-swept beaches, and in the most humid of jungle environments. Let’s take a look at how this sweet piece of glass performed.
