Tamron Announces the 70-300mm f/4.5-6.3 Lens for Sony Full-Frame Cameras

Building on its reputation for creating high-quality, affordable lenses for Sony full-frame cameras, Tamron has just announced the development of a new telephoto zoom lens: the 70-300mm f/4.5-6.3 Di III RXD.

Tamron claims it to be “the world’s smallest and lightest” 70-300mm zoom lens: it’s 5.8 inches (148 mm) long, has a diameter of 3.03 inches (77 mm), and weighs just 19.2 oz (545 grams).

The lens is moisture-resistant and its front filter diameter of 67 mm keeps it in line with all of Tamron’s other Sony full-frame lenses, meaning that filters can easily be shared.

The autofocus is driven by an RXD stepping motor, the same as that found in the highly popular 28-75mm f/2.8 and the recently released 28-200mm f/2.8-5.6. Tamron says that, like its other lenses, the 70-300mm f/4.5-6.3 will have excellent autofocus performance and deliver exceptional image quality.

Like the 28-200mm lens, Tamron has opted not to include stabilization in this telephoto zoom, probably as a means of keeping costs down. Users will have to decide whether their hands are steady enough to shoot at 300mm with an aperture of f/6.3.

The lens is due to go on sale in Fall and as yet the price is unconfirmed.

No stabilization on a 300mm lenses?
Yeah, no.
I also miss panning mode on lenses like Sigma 100-400mm.
I'm not even going to bother thinking about this lens.

IBIS does not help?

I can understand the lack of stabilization to keep the price down, this will be a great budget option for a "walkaround lens" for full frame owners.
