Tamron has announced that it’s developing a new 28-300mm F/3.5-6.3 Di VC PZD superzoom lens for full frame SLRs. A near-twin of the co-announced 16-300mm F3.5-6.3 for APS-C, it’s distinguished from the current model by featuring an ultrasonic-type ‘Piezo Drive’ autofocus motor, splashproof construction and more-compact design with a 67mm filter thread. It’ll be made in Canon, Nikon and Sony mounts; pricing and availability are to be confirmed. Learn more
