The ultra-wide zoom doesn’t just cover wide perspectives – the category also tends to be “ultra” pricey, not to mention oversized. But the new Tamron 12-20mm f/2.8, available in full-frame E-Mount and Z-Mount, slides into the category with not just a competitive third-party price but a lightweight design.
Beyond offering a tantalizingly more affordable ultra-wide zoom, Tamron's lens also marks a new era for the brand. The Tamron 12-20mm f/2.8 is its full name, dropping the usual “Di III VXD G2” jumble of letters at the end. (Tamron tells me the designation for APS-C and stabilization will remain, but this lens doesn’t fall in either category.)
