Ever wondered why they done make ‘super-zoom’ lenses for DSLR cameras, like they do with super zoom semi-pro models? Well, lensmaker Tamron has just unveiled an 18-400mm lens, which it calls “the world’s first ultra-telephoto all-in-one zoom lens”.
With a 22.2X zoom factor, the lens is currently being manufactured for APSC format sensors for Nikon and Canon bodies. The effective focal length on APSC format would make it a 28-600mm lens! At just 4.2 inches in length, and weighing in just over 700 grams, this could be the best option for the one lens that you may want to carry on vacation.
To pack so much optics into the small body, Tamron has used a new barrel design which has a three-step extension, claiming that the larger number of cams also“ensures comfortable operation and stability while zooming”. The lens is said to be quiet and acuurate in its focusing, employing Tamron’s proprietary Vibration Compensation system, which the company claims, reduces camera shake by up to 2.5 stops. it also has a zoom lock, which eliminates chances of ‘zoom creep’.
Going by what Petapixel has to say, the lens is probably a true multi purpose, with a minimum focus distance of 0.45cm and maximum magnification ratio of 1:2.9. Here are images from across the zoom range of the lens –
You can see loads more sample images shot by the lens here. At an aperture range of 3.5 to 6.3, we believe it is fast enough for the magnificent zoom and portability.
