his Tamron 100-400mm is a portable, ultra-telephoto zoom lens with excellent AF precision. The Low Dispersion glass corrects aberrations and the eBAND & Angular-Dependency coating suppresses reflections, giving images of amazing clarity. The lens barrel is made primarily of magnesium, making it lightweight so it’s ideal for handheld shooting over long periods of time. With a Minimum Object Distance of 1.5m and a maximum image magnification ratio of 1:3.6, the 100-400mm lets you soften the foreground or background to dramatically emphasize your subject at close range. Moisture-Resistant Construction and a fluorine-coated front element provide additional protection when shooting outdoors.
Excellent AF performance meets enhanced Vibration Compensation (VC)
Precise AF tracking and VC (Vibration Compensation) are essential to ultra-telephoto lens performance. Tamron’s Dual MPU highspeed control system helps make this possible. In addition to an MPU (micro-processing unit) with a built-in DSP for superior signal processing, the 100-400mm features a separate MPU dedicated exclusively to vibration compensation. With AF tracking and enhanced VC, you can enjoy shooting your most beloved subjects with stability and ease—even in low-light.
