The internal zoom design keeps the lens length fixed across the 24-70mm range, while the SSVCM motor delivers autofocus that is five times faster and 50% quieter than its predecessor. Focus breathing is reduced by more than half, and the 11-blade diaphragm paired with S-Line optics produces smooth bokeh and strong close-up performance at 0.32x magnification. This lens suits hybrid shooters and event photographers who need reliable gimbal balance and near-silent AF for both stills and video.
