With this lens, you can take pictures at shutter speeds approx. 3 stops slower than you ordinarily could without using a VR lens, expanding the range of usable shutter speed options and making telephoto shooting much easier without a tripod.. Optical design incorporates five ED glass elements for superior optical performance throughout the entire zoom range.. New G-design incorporates distance information for flash and ambient light exposure processes.. Resistance to water drops equivalent to those of telephoto AF-S lenses.. Built-in A/M switch enables instant switching from autofocus to manual focus (Lock mechanism provided).
