Verdict: 4.5 stars The Tamron 20-40mm F2.8 Di III VXD might sound like an odd sort of crossover lens somewhere between a wide-angle zoom and a kit lens, but with a 2x zoom range that sounds distinctly limiting. However, that 2x zoom range offers more framing and perspective variation than you might expect, the constant f/2.8 maximum aperture is excellent at this price and the handling is smooth, light and sweet. I like it a lot.
