Tamron has used PMA in Las Vegas as the launchpad for a 28-300mm lens that boasts a Vibration Compensation (VC) mechanism designed to help reduce the effects of camera shake.

Designed for digital SLRs with an APS-C size imaging sensor and a full-frame sensor the 28-300mm f/3.5-6.3 XR DI VC LD Aspherical [IF] Macro will deliver the 35mm viewing angle equivalent of a 43-465mm zoom on a camera with an APS-C size sensor, according to the company.

This is how Tamron described its ‘anti-vibration’ technology at the PMA show in Las Vegas: ‘The proprietery VC mechanism developed by Tamron features a triaxial configuration using three pairs of driving coils and slide balls around the compensator group of the lens’ optical system. Since the compensator lenses are supported with rolling friction of the balls, the response performance is enhanced and the construction is simple, which results in the compactness of the lens.’ Camera shake is detected using a ‘gyro sensor’, adds the company.

The lens weighs 550g and is 99mm long, according to the specification released at the PMA show. It is expected to be available in Canon and Nikon mounts.

The macro magnification is 1:3, says Tamron.

Also announced is an SP 70-200mm f/2.8 DI LD [IF] Macro, billed as a fast, lightweight tele zoom. It delivers the 35mm equivalent of a 109-310mm lens (on an SLR with an APS-C size sensor), using a 1.55x conversion factor, and will be out in Canon, Nikon, Pentax and Sony mounts

AP is meeting with Tamron UK representatives in Las Vegas at the time of writing and we will keep you posted with availability and pricing as soon as we can.

? We are still trying to confirm whether music legend Dolly Parton attended the PMA show in Las Vegas yesterday.

The singer was understood to have appeared soon after opening time on Thursday 8 March.

She was accompanied by a mass of security personnel… and, inevitably, a bunch of eager photographers attending the show.

Caught up in the excitement was a member of the UK photographic press who happened to be standing near the Samsung stand at the time when the fuss broke out.

However, following our enquiries, we understand that she may have been a lookalike hired by a local company as a PR stunt.
