Tamron Di III F051 20mm

★★★★★ 4.5 (437)

Weighing just 215g and sealed against moisture, this lens pairs a 1:2 maximum magnification with a 4.7-inch minimum focus distance for near-macro versatility in a compact full-frame design. Its optical formula uses three ED and one aspherical element to control aberrations, while the f/2.8 aperture keeps the build remarkably portable and discreet. This lens is best for hikers and travel photographers who want a lightweight wide-angle prime that can also capture detailed close-ups of flora and fauna.
