Sigma 750975
Combining a 100-400mm reach with a relatively light 1100g build, this lens stands out for full-frame mirrorless portability. Its dust- and splash-proof brass mount and optical design that minimizes flare add rugged, practical reliability. This is best for outdoor enthusiasts and travelers who need handheld telephoto range without the bulk of traditional pro glass.
