Tamron has announced the 14-150mm F/3.5-5.8 Di III (model C001), a superzoom lens for Micro Four Thirds cameras which offers a 28-300mm equivalent range. It uses a stepper motor for silent autofocus (including during video recording), but doesn’t include image stabilisation. This means that it’s rather less suited to Panasonic cameras than it is to Olympus models. It will be available on June 26th for $ 589.
