It’s always refreshing to see a third-party lens maker venture into new ground, and with the 70-210mm f/4 Di VC USD, Tamron has spotted a gap in the market and made a genuinely interesting alternative to the 70-300mm lenses that Canon and Nikon offer as upgrade options from their entry-level telezooms. It strikes a very attractive balance between image quality, robustness and portability, making it a particularly tempting option for users of mid-range APS- C DSLRs such as the Canon EOS 80D or Nikon D7500.
Unsurprisingly, this lens isn’t quite as stunning as its f/2.8 sibling, but it comes pretty close, given that it costs less than half the price. Indeed, my main gripe is that the front-mounted zoom ring compromises handling. If you can live with that, though, it’s a great choice for enthusiasts who value image quality over telephoto reach.
