The Sonnar

* 4/210 lens is an autofocus telephoto

lens similar to a 135 mm lens on a 35 mm Contax

SLR.

The optical system was designed using the latest

technology, incorporating internal focusing (IF) and the

most recent optical glass types. It shows outstanding

performance.
The Sonnar

* 4/210 lens can deliver telephoto shots of

high quality and perfect corner-to-corner uniformity

even at wide open aperture.

This is what fashion photographers need to blur out

unwanted background with a shallow depth of field,

making their subjects stand out impressively.

Combined with the autofocus of the Contax

645 the

Sonnar

* 4/210 lens brings new possibilities to such

fields as fashion and beauty photography, sports

celebrities in action, performing artists on stage,

musicians in concert, playing kids, pets and the like. The

resulting images can be blown up to poster size with

significantly better results than a 35 mm photo could

deliver.

Preferred use: portraits, kids, pets, animals, fashion,

beauty, sports and action
