CP+ 2013: Tamron is showing off its newly-announced 14-150mm F3.5-5.8 Di III VC stabilized superzoom lens for Micro Four Thirds, while Olympus has a revised version of its 75-300mm F4.8-6.7. Though Tamron hasn't yet announced the price or availability of the 14-150mm, the prototype it has on display is working and the company gave us a hint about how much it will charge.

The Tamron 14-150mm prototype for Micro Four Thirds

In addition to having a prototype of the lens in a cabinet, Tamron also has a working prototype that they demonstrated for us. Even in pre-production form the stepper motor provides impressively fast and quiet focusing - supporting the company's suggestion that it'll work well for video shooting. Meanwhile, our first impression is that the Vibration Correction offers the same disconcertingly steady stabilization the company's other VC-equipped telephoto lenses offer.

The lens' metal housing gives a nice feel to the lens and helps result in a package that strikes a good balance between having some substance to it, without it then being too heavy. Although pricing hasn't yet been decided, Tamron told us that it would be 'competitive,' saying 'we can't charge too much when there are also lenses from Olympus and Panasonic.'

Meanwhile, Olympus was also showing the latest version of its tele-zoom lens for Micro Four Thirds. The Mark II retains the same optical design as the original but adds the company's 'ZERO' (Zuiko Extra-low Reflection Optical) coatings to reduce internal reflections and fight ghosting and flare. The lens body has been redesigned to match the recent Micro Four Thirds zooms, such as the 14-42mm II R. In addition the list price has been substantially reduced - with Olympus now asking for around €549, rather than the €899 MSRP of the original version.
