A constant f/2.8 aperture across the 50-140mm range (76-213mm equivalent) pairs with 5 ED elements and Nano-GI coating for sharp, flare-resistant images. The triple linear motor delivers fast, near-silent autofocus, while over 20 weather-sealing points and optical stabilization support handheld shooting in rain or temperatures down to 14°F. This lens suits event and portrait photographers who need reliable telephoto reach and low-light performance without switching primes.
