28-105mm F2.8-4 Aspherical

New fast 28-105mm lens from Sigma

Sigma’s 28-105mm F4-5.6 was voted European Lens of the Year ’94-95. Hardly surprising that it then proved to be one of Sigma’s best selling and most popular lenses – so why discontinue it?

Sigma, with the benefit of the very latest technology, have designed an even better 28-105mm lens!

The Sigma 28-105mm F2.8-4 Aspherical benefits from a combination of aspherical lens and 4 group zoom system. The design means the lens delivers pin-sharp images with superior contrast and resolution plus improved edge definition.

Amazingly the F2.8 maximum aperture is still housed in a lightweight and compact lens barrel which sets a new standard of excellence for photographers who wish to travel light.

The lens has an internal focussing syste with non-rotating front elemtn which filter users find essential. Sigma’s durable Zen finish, a matched lens hood and 3 year warranty make the 28-105 F2.8-4 Aspherical lens outstanding value for money at just £269.95
