Tamron has officially announced the 28-300mm f/4-7.1 Di III VC VXD lens for Sony E-mount, release date on August 29th, available for pre-order at B&H Photo Video.
The TAMRON 28-300mm F4-7.1 VC is an all-in-one zoom lens for Sony E-mount full-frame mirrorless interchangeable lens cameras. This lens covers a broad focal length range from 28mm wide-angle to 300mm telephoto with superior imaging performance. It achieves a zoom ratio of 10.7x with a length of just 126mm (5in) and weighs only 610g (21.5oz). The lens is equipped with the VXD (Voice-coil eXtreme-torque Drive) linear motor focus mechanism, enabling it to focus quickly and accurately throughout the entire zoom range. The lens also features TAMRON’s VC (Vibration Compensation) mechanism to ensure sharp hand-held images when shooting at the 300mm telephoto end and in low-light conditions. With an MOD (Minimum Object Distance) of 0.19m (7.5in) and a maximum magnification ratio of 1:2.8 at the wide end, the lens allows users to enjoy the world of wide macro photography. And it includes the Focus Set Button and a connector port for the dedicated TAMRON Lens UtilityTM software independently developed by TAMRON to expand the scope of expression for still images and video. The lens features Moisture-Resistant Construction, and the front element has a protective Fluorine Coating. The new 28-300mm F4-7.1 VC lets users take photos in an extremely wide range situations with just one lens.
Unfortunately, I think this lens is a bit of a letdown for the price point. That f/7.1 aperture at 300mm is just too slow for $899, and in my experience, these superzooms really struggle with corner softness. I've had issues with similar designs where the focus hunts a lot in anything but perfect daylight. If you want a more cost-effective setup, these are better options imo:
