Tamron 100-400mm f/4.5-6.3 Di VC USD
Generally speaking, we expect long telephoto zooms to be large, heavy and cumbersome items. Last year, however, Sigma bucked this trend with the announcement of the100-400mm f/5-6.3 DG OS HSM | C. Unlike the company's Sport and Contemporary150-600mm zooms, which are aimed at advanced photographers, it's a lens that's designed for keen amateurs and aspiring enthusiasts who want to get close to distant subjects without having to spend a four-figure sum. It quickly became a hit with its intended audience, as well as full-frame users who liked the idea of owning a lightweight and versatile zoom for travelling and general use.
Since then, Tamron has launched its own variant in the guise of the 100-400mm f/4.5-6.3 Di VC USD. The concept is similar to its Sigma rival, but with subtle differences between the two, it begs the question, which makes the better choice?
