The Tamron 20-40mm f/2.8 Di III VXD is yet another different take on the 'standard' zoom lens. Tamron already makes alternatives to 'trinity' wide-angle and standard zooms, and the new 20-40mm retains the same fast and constant f/2.8 aperture rating but delivers a more unusual zoom range. For walkabout and travel photography, size matters. Despite its fast and constant f/2.8 aperture, this lens is conveniently small at 74 x 87mm and very lightweight at 365g. Although full-frame compatible, the lens works equally well on Sony's APS-C format mirrorless cameras, on which it gives a very useful 'effective' zoom range of 30-60mm.
