The constant f/2.8 aperture, class-leading 37.8-inch minimum focus distance, and 0.25x magnification distinguish this telephoto, with XA and ED elements plus Nano AR Coating ensuring high resolution and flare suppression. Weighing just 797 grams, it’s exceptionally portable for an f/2.8 zoom, and its parfocal design with minimal focus breathing serves video shooters reliably. This lens is best for event and portrait photographers and videographers who need fast, precise autofocus and robust weather sealing, though travel photographers may find its size limiting.
