Tamron has announced a new 18-400mm F3.5-6.3 Di II VC HLD APS-C lens billed as the world’s first to cover the extended range. Having reviewed the Sigma and Tamron 18-300’s in a previous video this might be the one for those that prioritize convenience. For $649 you get 22.2x zoom ratio covering wide angle shots from 28mm to ultra-telephoto 640mm (Canon crop ratio). The lens also features a maximum magnification ratio of 1:2.9 so you can enjoy tele-macro photography. With the new design comes their new LD (Low Dispersion Glass) with an ashperical lens to control the chromatic aberration (color fringing) all-in-one lenses are known for typically. For it’s size, Tamron managed to make it quite small at 4.8 inches long and 24.9 ounces, in comparison Sigma’s 18-300 Contemporary Lens clocks in at 4 inches and 20.6 ounces with 100mm less in focal length. The 18-400mm lens also incorporates 2.5 stops of stabilization with a zoom lock to get the sharpest shots possible from the 640mm focal range. If you are interested the 18-400mm gets you that all-in-one convenience for a decent price. As with our 18-300mm comparison, there is a cost for the benefit, we’ll have a review out soon on this new lens.
I have never owned a Tamron lens but I thinking about this one when it comes out at the end of the month. What are your thoughts ??
