Introducing the World's First 18-400mm Lens

Now you can go macro, micro and anywhere in between.

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.

Here’s are images shot at 18mm, 50mm, 100mm, 200mm, and 400mm respectively:

"minimum focusing distance of 17.7in (0.45cm)" Something wrong there.

Zoomed right in it looks bit soft to me here, but that could be this web page.
Then again for $649 you get what you pay for.

Opens up a few nice possibilities.

Well, they finally made the true all-in-one lens for doc/ location work! Now for the fight on who can get a constant F4 through the range, or the psychos who come out with 2.8 for $4,000. Another good step to support up and coming filmmakers and photographers, though!

This would be a killer lens to take backpacking. Throw this and a fast 24mm for astrophotography into your pack and you'd be set for just about anything. Pity it only covers APS-C!
