Sony FE 24-240mm F3.5-6.3 OSS

The Sony FE 24-240mm F3.5-6.3 OSS is a variable maximum aperture full-frame (FE) superzoom lens for the Sony E-mount, announced by Sony on March 4, 2015.

Though designed for Sony's full frame E-mount cameras, the lens can be used on Sony's APS-C E-mount camera bodies, with an equivalent full-frame field-of-view of 36-360mm.

Build Quality
The barrel of the lens telescopes outward from the main lens body as it's zoomed in from 24mm to 240mm. The lens does not feature a zoom lock but isn't easily susceptible to zoom creep thanks to a tighter zooming mechanism. It also features a weather resistant design.

Features
The lens features Sony's OSS to help reduce motion blur while using slower shutter speeds. The maximum aperture of the lens varies from f/3.5 at 24mm to f/6.3 at 240mm. The 24-240 includes five aspherical lens elements and one ED lens. The front element does not rotate but uses two telescoping tubes to extend forward by 76.4 mm when the lens is zoomed from 24 mm to 240 mm.
