And at 240mm focal length the Sony has 20% more reach on the long end compared to the Tamron and Nikon. This gives the Sony and Nikon a 9 degrees wider angle of view on the short end (84 degrees vs. Ĭoverage: With its 10x zoom-range the Sony has the upper hand over the 7.1x coverage of the Tamron and the 8.3x range of the Nikon. So the Tamron maintains a 2/3-1EV advantage in light gathering power and subject isolation over the Sony resp. The Tamron achieves its slowest focal ratio of f5.6 from 150mm focal length onward. At 70mm focal length the Tamron is at f4.0, the Sony at f5.0 and the Nikon at f6.0. įocal ratio: The Tamron starts with a bright f2.8 focal ratio at the short end which is 2/3 of a stop brighter than the Sony and 1 stop brighter than the Nikon. The Sony and Nikon are of a similarly complex construction. Optics: The Tamron 28-200mm f2.8-5.6 Di III employs 18 elements in 14 groups including 3 special dispersion elements and 4 aspherical elements. But then you gain a constant f2.8 aperture. lens hoods) – a sizeable difference compared to the new super-zoom.

Btw.: The Tamron 28-75mm f2.8 Di III plus Tamron 70-180mm f2.8 Di III weigh 1.4kg (3.1lb.) together (incl. The Sony is 744g (26.2 oz.) + 39g lens hood, the Nikon is 565g (19.9 oz.) + 22g lens hood. Complementing the new zoom lens with Tamron’s 17-28mm f2.8 Di III to cover the very wide end makes for a lightweight combo of only 1kg (2.2 lb.) covering a 12x zoom range. Weight: 558g (19.7 oz.) plus 25g for the lens hood. All three lenses have a double barrel design and extend when zoomed to the longest focal length: The Tamron to 201mm, the Sony to 221mm, the Nikon to 215mm (incl. Size (diameter x length): At 74 x 117mm (2.9 x 4.6in.) plus 28mm for the lens hood (which is 87mm in diameter) the new Tamron is a pretty small lens, even a bit slimmer than the Sony at 81 x 118mm (3.2 x 4.7in) + 36mm lens hood. As usual I’ve rated the features with a (or ), when it’s better than average or even state of the art, a if it’s standard or just average, and if there’s a disadvantage. PS – if you’re interested in the other full-frame zoom lenses for E-mount in Tamron’s line-up check out my in-depth reviews: Tamron 17-28mm f2.8 Di III RXD review / Tamron 28-75mm f2.8 Di III RXD review / Tamron 70-180mm f2.8 Di III VXD. The Nikon may look like an odd choice in this comparison but Tamron has announced that they are working on Z- and RF-mount versions of their lenses. In my tests I compared the new Tamron 28-200mm f2.8-5.6 Di III to the alternative from Sony – and the equally new Nikon Z 24-200mm f4.0-6.3 VR. The new Tamron has no optical stabilization and relies solely on the image stabilization provided by the Sony Alpha mirrorless cameras while the Sony FE 24-240mm f3.5-6.3 OSS has optical image stabilization. lighter than the alternative from Sony, the FE 24-240mm f3.5-6.3 OSS, and both lenses extend while zooming. Physically, the 28-200mm f2.8-5.6 Di III is a little smaller and 200g / 7 oz. Announced in June 2020, it is a more affordable and lightweight alternative to carrying Tamron’s 28-75mm f2.8 Di III plus 70-180mm f2.8 Di III zoom lenses although you lose-out on a constant f2.8 focal ratio – and some image quality. The Tamron 28-200mm f2.8-5.6 Di III RXD (model A071) is an all-in-one zoom designed for Sony’s Alpha mirrorless cameras and corrected for full-frame sensors. Tamron 28-200mm f2.8-5.6 Di III RXD review The shorter range is arguably the biggest factor to weigh-up, but if you don’t need to zoom as wide as 24mm, Tamron has designed a compelling super-zoom which clearly earns a Highly Recommended! Buy it now! Check prices on the Tamron 28-200mm f2.8-5.6 Di III at Amazon, B&H, Adorama or WEX! Alternatively get yourself a copy of my In Camera book or treat me to a coffee! Thanks! On the downside, the wide end starts at 28mm versus 24mm on rivals, it has no optical image stabilization, and there were some strange autofocus-misses which might be a problem with my copy of the lens - but worried me nonetheless. But most importantly its optical performance is very convincing, astonishingly so for a 7.1x zoom lens. But the Tamron offers a brighter focal ratio of f2.8 at the wide end, achieves a magnification of 1:3 from 0.19m, and is weather-sealed. At the time of writing, it was only available in Sony E-mount, and costs more in some regions than Sony’s own FE 24-240mm super-zoom, while lacking its broader zoom range and optical stabilization. Summary The Tamron 28-200mm f2.8-5.6 Di III is a small and light all-in-one zoom designed for mirrorless cameras with full-frame sensors.
