Introduction ALPA Lens Module Contax 645

10.2017 - Lens Module for Contax 645

Thanks to the appropriate module, the exclusive optics from the Contax 645 series can now also be used with ALPA cameras and modern backs. For the launch we are offering the module as part of a kit with the ALPA 12 FPS at a special low price.

After lenses from the Hasselblad H and V ranges, ALPA is bringing new life to another classic: With the Contax 645 module, the lenses from this legendary medium-format series can be combined with the modern ALPA 12 FPS and a digital or analogue back. Because even once the Contax bodies slowly reach the end of their lives, the optics are still functional. ALPA previously offered a solution with the Shift Adapter Contax 645. We have now reworked this and replaced it with the new lens module Contax 645.

In total, nine different lenses and one teleconverter were manufactured by Carl Zeiss under the name Contax 645 until 2005. More than ten years after production ceased they still count as some of the most powerful in the market and are extremely popular. The optics have an interesting focal length and aperture, which can be used creatively thanks to the ALPA lens module.

Fits ALPA 12 cameras

Particularly when it comes to taking portraits, the fast lenses from the Contax 645 series show off their strengths, with their narrow depth of field. However, use of the lenses with new cameras is limited. With the adapter, ALPA is building a bridge and offering photographers the option to connect the CONTAX-645 with an ALPA-12 body.

The Contax 645 lens module can be attached directly to the ALPA 12 FPS or used with another ALPA camera via the ALPA Silex control device and the Electronic Lens Adapter (ELA). This factor also makes it possible to shift,
particularly with a sensor size of 34x44mm.

By using an additional adapter, a film roll back or a digital back can be attached, which has an integrated electronic shutter. The IQ3 100MP backs from Phase One as well as Sinar S30 and S45 meet these requirements.

Easy to install, electronic control

While older lenses have to be adjusted by hand with modern cameras, photographers can use the SILEX controller or the ALPA 12 FPS camera to electronically control the optics from the Contax 645 series. This enables the electromechanical diaphragm as well as the focusing motor to be adjusted. An exception in this respect is the Apo-Makro-Planar 4/120, as it does not have any autofocus function. Setting up the module is very simple: It’s possible to use it to take photographs as soon as it is attached, and does not require any additional setting up.

The module is compatible with the following lenses

Sonnar 2.8/140
Sonnar 4/210
Distagon 2.8/45
Distagon 3.5/35
Distagon 3.5/55
Vario-Sonnar 4.5/45-90
Tele-Apotessar 4/350
Planar 2/80
Apo-Makro-Planar 4/120

Important note: The Mutar 1.4x teleconverter is the only lens from the Contax 645 series not yet covered by the module.
