Tamron 70-210mm F/4 Di VC USD announced

The 70-200mm constant aperture telephoto zoom is a key part of any enthusiast or pro photographer’s kit. But 70-200mm f/2.8 lenses are big, pricey and heavy, so a 70-200mm f/4 is a lighter and more cost-effective solution.

What’s different about Tamron’s new lens is its slightly longer focal range of 70-210mm. On an APS-C format camera, that’s equivalent to 105-315mm.

Designed for “superb” optical performance across its zoom range, this new Tamron lens also offers a maximum magnification ratio of 1:3.1. It’s not a macro lens, but it can get a lot closer to your subjects than most for some striking close-ups.

Inside is an internal zoom mechanism which means that the lens doesn’t change length as you zoom pin and out, a Dual MPU (micro-processing unit) for fast and accurate USD (ultrasonic drive) autofocus, and Tamron’s own VC (vibration compensation) optical image stabilisation system offering a claimed 4 stop shutter speed advantage. The optics consist of 20 elements in 14 groups, with LD (low dispersion) elements to counter lateral chromatic aberration.

The front element doesn’t rotate during focusing, so it’s ideal for filters, and with a moisture resistant construction and Fluorine Coating, the 70-210mm should be able to cope with wet conditions outdoors.

The 70-210mm F/4 Di VC USD is also compatible with Tamron’s 1.4x (Model TC-X14) and 2.0x (Model TC-X20) Teleconverters, which effectively turn the lens into a 98-356mm f/5.6 and 140-420mm f/8 lens respectively.

The new lens will be available in both Canon and Nikon DSLR mounts, and both use electromagnetic diaphragm control, so Nikon users will need to make sure their cameras are compatible – older models may not be. Both versions go on sale in April 2018 with a suggested retail price of £699.
