Tamron has developed what it is calling the “the world’s first ultra-telephoto all-in-one zoom lens.”  The F3.5-6.3 Di II VC HLD lens boasts a range of 18-400mm and has a very handy zoom ratio of 22.2x.

This incredible zoom ratio is made possible by a newly developed moisture-resistant lens barrel design which utilizes three-step extensions. Tamron says the "larger number of cams ensures comfortable operation and stability while zooming." It boasts a minimum focusing distance of 17.7in (0.45cm) and maximum magnification ratio of 1:2.9.

The lens was designed for Canon and Nikon APS-C cameras and has an equivalent focal length range of 28-600mm. Despite being an all-in-one zoom lens that achieves 400mm ultra-telephoto, Model B028 is light and compact with a total length of 4.8in. and an extremely light weight of 24.9oz. It's a very portable option for the type of range you're able to acheive.

To keep that camera shake down, the lens employs Tamron’s proprietary "Vibration Compensation" system (said to reduce camera shake by up to 2.5 stops) and Zoom Lock to prevent zoom creep.
