The updated optical design and VXD linear motor deliver sharper resolution and faster, quieter autofocus than its predecessor, all in a weather-sealed, 540g body. Its standout 1:2.7 magnification at a 7.1-inch minimum focus distance adds genuine close-up versatility rarely found in a constant f/2.8 standard zoom. This lens is best for hybrid shooters and portrait photographers who need a lightweight, do-it-all workhorse without the premium price of first-party glass.
