Tamron Di III A062 20-40mm
Combining a constant f/2.8 aperture with a compact 365g build, this lens stands out for its fast VXD linear autofocus and useful 20-40mm range on full-frame Sony E-mount bodies. Its 6.7-inch minimum focus distance and moisture-sealed construction add practical close-up capability and durability in a portable package. This lens is best for travel photographers and vloggers who prioritize a lightweight, fast standard zoom over telephoto reach.
