The Tamron 18-400mm is the Worlds first ultra-telephoto 22.2x all-in-one zoom lens. This all-in-one zoom lens is ideal for travel and everyday use. Switch from wide-angle to ultra-telephoto without changing lenses, making it faster and easier to capture a much wider range of subjects including travel scenes, wildlife, action sports, landscapes, cityscapes, portraits etc.
Excellent image quality across the entire zoom range
The optical construction consists of 16 lens elements in 11 groups. The use of specialized glass elements such as LD (Low Dispersion) and aspherical lens elements effectively minimizes wide-ranging aberrations, including chromatic aberrations and distortion, thereby assuring outstanding image quality. Optimum power distribution among the individual lens element groups achieves both the optical performance and the compact size necessary for an ultra-telephoto all-in-one zoom lens that boasts 400mm focal length. Also, it enables tele-macro photography with a maximum magnification ratio of 1:2.9.
Lightweight and compact design
This Lens is light and compact with a total length of 121.4mm and a weight of 705g. A new lens barrel design utilizing three-step extensions was developed to enable the necessary elongation to produce a 22.2x zoom ratio.
HLD motor provides
The AF drive system uses Tamron’s exclusive HLD (High/Low torque modulated Drive) motor. The power-saving HLD motor produces outstanding driving torque, and adjusts motor rotation from low to high speed to enable accurate and quiet focusing. The HLD motor takes up less space thanks to its small size and circular arc shape that allows the size of the lens to be reduced.
Vibration Compensation system
It is equipped with Tamron’s original VC (Vibration Compensation) system, which effectively curbs camera shake under low light conditions (such as a dimly lit room or at dusk) and while taking ultra-telephoto pictures. This greatly expands opportunities for casual handheld shooting.
This lens features Moisture-Resistant Construction to ensure worry-free shooting as well as confidence while shooting under adverse weather conditions. Also, the Zoom Lock mechanism prevents undesired movement of the lens barrel under its own weight when the camera is angled downward while walking.
