Buried at the end of its press release announcing the α6000, Sony has revealed pricing and availability for its previously announced FE 70-200mm F4 G OSS. Like the other A7-compatible FE lenses it's not especially cheap, though; the image-stabilised telezoom will be available in March for about $1500 (or £1240 in the UK). In context, this is about $100 more than Nikon's recent AF-S Nikkor 70-200mm f/4G ED VR; then again it looks as though Sony is generous enough to give you a tripod mount ring in the box.
The lens will work on both full frame and APS-C sensor E-mount cameras, offering a 105-300mm equivalent range on the latter. It offers a full complement of external controls, including a focus limiter switch, OSS mode switch for normal shooting or panning, and an array of focus hold buttons. Autofocus is provided by dual linear stepper motors, and the lens is dust- and moisture- resistant. Overall it looks like the first really 'serious' telephoto zoom for a mirrorless system to reach the market, and real statement of intent by Sony.
Sony has announced the price of its previously announced full frame E-mount 70-200mm F4 G OSS telephoto zoom lens (model SEL70200G). This lens will be available in March for about $1500.
