How Good is the Tamron 17-70mm F/2.8 Di III-A VC RXD Lens for X

Por un escritor de hombre misterioso

Japanese lens manufacturer Tamron has been in the photographic optics industry since 1950, making them one of the oldest Japanese third-party lens manufacturers. Back in 1992, they were the first to produce an ultra-wide range AF 28-200mm zoom lens, and also had a line of professional lenses, including the SP AF 300mm f/2.8 available for Canon, Minolta and Nikon mounts. Tamron still makes unique lenses, including the 17-70mm f2.8 Di III-A VC RXD now available for Fujifilm X Mount. This is the first mid-range 4.1x zoom lens with a fast f/2.8 constant aperture for the APS-C format. Fujifilm’s red label XF16-55mmF2.8 R WR only has a 3.4x zoom range, while the 5x zoom range XF16-80mmF4 R OIS WR only has a maximum aperture of f/4. I had a chance to review the Tamron and compare it against Fujifilm’s own mid-range zoom lenses. Let’s start with the specifications.
