The advanced optical construction of the AF 70-200 f2.8 with Tamron’s Multi Lens coatings minimise the possibilities of flare, with three LD (low dispersion) elements effectively compensating for lateral and on-axis chromatic aberrations, resulting in edge-to-edge sharpness and high-contrast image quality to challenge far higher priced alternatives from the mainstream camera brands.
It enables the user to cover a focal length range of 70mm medium telephoto to 200mm telephoto when mounted on a 35mm full-size DSLR camera (109mm to 310mm equivalent* on a DSLR camera equipped with an APS-C sized image sensor). (*) Tamron's conversion ratio is 1.55x
Size & Weight - The Tamron 70-200 f2.8 lens is extremely compact at just 195mm long and 89.5mm diameter with its advanced optical design keeping weight down on the lens itself to a mere 1150g.
One-touch Auto/Manual Switchover Mechanisms - The models for Nikon and Canon cameras can easily and quickly be switched between Auto and manual focus simply by sliding the focus ring back or forwards. (Sony and Pentax systems require AF/MF switchover operation on both the camera and lens).
Whilst in Autofocus the IF (internal focusing) system prevents the focusing ring from rotating ensuring great handling and stability at all times.
Slip the focus ring back and you are immediately in Manual Focus mode allowing you to decide exactly where you want to focus your subject to take control of your depth of field or simply to focus on a particular area of the subject without having to reframe or access alternate focus modes via your cameras menu system. The Manual focus system is well weighted and has a quick action to enable focusing from close to infinity without losing balance and stability.
Detachable Tripod Grip Ring - The lens is supplied with a lightweight and rigid aluminium removable tripod socket.
Flower-shaped Lens Hood - A flower-shaped lens hood is included as a standard accessory. The special hood provides optimum shading of superfluous light whilst allowing full use of the maximum zoom range.
