World acclaimed ultra-telephoto zoom reborn; meet the all-new next generation
The SP 150-600mm G2 (Generation 2) ultra-telephoto lens with upgraded optical performance enables handheld shooting with remarkable definition. This new lens builds upon the success of the current SP 150-600mm (Model A011) which Tamron first introduced in December, 2013, including better overall optical performance and faster AF speed, VC enhancements, plus Fluorine Coating, FLEX ZOOM LOCK and tele converter.
Rebuilt from the ground up to meet Tamron’s strict quality standards and design specifications, this new zoom combines smart engineering and high performance with quality craftsmanship, durability and user friendliness.

Enhanced optics meet greater versatility
Focal length: 600mm Exposure: F/6.3 1/400 sec ISO1250
The SP 150-600mm G2 includes three LD (Low Dispersion) lens elements which completely eliminate axial and transverse chromatic aberrations. It also features upgraded optical construction (21 elements in 13 groups).
Anti-reflection technologies, eBAND (Extended Bandwidth & Angular-Dependency) Coating and BBAR (Broad-Band Anti-Reflection) Coating improve light transmission and suppress internal reflections, including light reflected off the camera’s image sensors. So even when taking a backlit or semi-backlit photograph, ghosting and flare caused by reflected light are fully eliminated.
Additional enhancements expand the lens’ versatility. For example, MOD (Minimum Object Distance) has been reduced to 2.2m (86.6 in) so you can enjoy tele-macro photography and dramatic bokeh.

Capture the moment with sharpness and accuracy
Focal length: 350mm Exposure: F/6.3 1/1600sec ISO400
The Model A022 is equipped with the USD (Ultrasonic Silent Drive) ring-type motor that delivers excellent responsiveness and control. AF speed is significantly improved from current model, and it enables accurate high-speed focus even when capturing moving subjects.
When shooting with AF, the Full-time Manual Focus override allows you to instantly make fine focusing adjustments manually, without having to switch between modes.

FLEX ZOOM LOCK mechanism enables zoom lock at any position
FLEX ZOOM LOCK mechanism quickly locks or unlocks the zoom at any position simply by sliding the zoom ring. Photographers can shoot from any angle without the zoom extending unintentionally. Additionally, the customary Zoom Lock switch prevents unwanted barrel extension during transportation.
