This version II lens has been improved over its predecessor with enhanced reproduction of fine details across the frame and faster, more responsive focusing.
Designed for full-frame A-mount cameras, this 70-400mm zoom covers a vast telephoto to super telephoto zoom range that make it suitable for close-up portraits as well as distant action. Also, it can be used on APS-C format cameras where it will provide a 105-600mm equivalent zoom range.
A variable f/4-5.6 aperture allows the lens to be more compact and lightweight than comparable options with this focal length.
Two extra-low dispersion glass elements are featured in the lens design to help reduce chromatic aberrations and color fringing for improved clarity and color neutrality.
A Nano AR Coating has been applied to reduce surface reflections, flare, and ghosting for increased contrast and color rendering in strong lighting conditions.
An SSM autofocus system with an enhanced algorithm and new LSI drive circuit provides quick, quiet, and precise focusing and much more responsive performance in tracking modes. The lens also features an internal focusing design that keeps the overall size constant and helps achieve a minimum focus distance of 4.9' with a magnification of 0.27x.
An electronic focus range limiter switch allows you constrain the usable focus range between a set limited range or full for improving focus speed, and three focus hold buttons are also featured to manually stop the autofocus at a specified point.
Dust and weather-sealed construction benefits using the lens in inclement shooting conditions.
The lens is equipped with a removable and rotating tripod collar for added stability and reducing strain on the camera's lens mount.
Rounded nine-blade diaphragm contributes to a pleasing bokeh quality when employing selective focus techniques.
The included lens hood features a filter access window for making adjustments to rotating filters.
This lens is compatible with Sony's 1.4x and 2x teleconverters which can increase the effective focal length to 98-560mm and 140-800mm, respectively.
