Schneider-Kreuznach Apo-Digitar super wide-angle lenses

Adaptation of the fully symmetric (i.e. minimum distortion) Schneider-Kreuznach Apo-Digitar 5.6/24 mm and 5.6/35 mm lenses with Copal or Schneider-Kreuznach shutters. The extremely short back focal distance and other technical reasons demanded the development of an unique focusing device by ALPA. Schneider-Kreuznach is preparing a version of the 5.6/35 mm lens with an image circle of 90 mm diameter which makes this lens even more interesting and versatile for digital as well as for analog photography.

Please note, that the pictures of the lens mounts are pre-series and may change without notice.
Linhof/Rodenstock ALPA 95 mm Technikar

Another unique lens that gives palpitations to every connoisseur of photographic lenses: the legendary Linhof/Rodenstock Technikar 3.5/95 mm in Copal Press (max. 1/125 s) and with a Schneider helical mount. The same optic was used for the famous Linhof 220 camera but it was not interchangeable there - with the ALPA 12 it is fully so.

Technical Data
Image circle: min. 91 mm
Optical design: 4 elements in 3 groups
Front thread: M58 x 0.75, with the standard step-up ring M67 x 0.75
Minimum focusing distance: 1.5 m (5 ft)
Weight: 382 g
Length at infinity: 104 mm

Schneider-Kreuznach 120 mm Macro-Symmar lens

Adaptation of the Schneider Macro-Symmar 5.6/120 mm HM lens with a new helical mount offering 19 mm travel. Using this helical mount, a minimum focusing distance of 110 cm is possible. Together with our three new macro adapters a continuous range from 1:1 up to infinity without any gap becomes reality.


Schneider-Kreuznach 180 mm Apo-Symmar and Schneider-Kreuznach 250 mm Apo-Tele-Xenar

Adaptation of the Schneider Apo-Symmar 5.6/180 mm L and the Schneider Apo-Tele-Xenar 5.6/250 mm lenses round off the already impressively wide range of high-end optics for the ALPA 12.


A set of macro adapters

Three new macro adapters of 16 mm, 34 mm and 52 mm size open the world of macro photography with all ALPA lenses. Each can be used alone or in any combination. They can be mounted in the front as well as in the back of the ALPA 12 camera bodies - another proof of the immense versatility of the concept behind the ALPA 12 system.


Lateral shift lensboards

A decentered lensboard for the exclusive and new Schneider-Kreuznach ALPA Apo-Helvetar 5.6/48 mm as well as for the Schneider-Kreuznach Super-Angulon 5.6/38 mm XL. With this lensboard, in addition to the integrated vertical shift of the ALPA 12 SWA, a lateral shift left/right of a fixed 8 mm is possible.


Adjustable adapters for digital backs

New back adapters for Hasselblad V, H1, Contax 645 and Mamiya 645 back-mounts. They are adjustable with shim kits so that a perfect and precise interchangeability of ONE digital back with SEVERAL camera bodies becomes possible - this is not as obvious as one might think. Of course, our proven standard back adapters for use with Hasselblad V, Mamiya RB67 and Horseman 6x9 mounts continue to be available.


ALPA roll-film backs

Re-designed roll-film backs based on the beautifully made and extremely robust Linhof Super-Rollex backs, modified for ALPA (e.g. tolerances of only +/- 2/100mm flange focal distance measured at the film guiding rails) for 6x7/120 and 6x9/120. Other formats on request.


Fresnel screen

A new Reflexite Fresnel screen to be used in addition to our actual groundglass made of floatglass. Following our general policy, this new Fresnel screen can be retrofitted to the earlier ALPA groundglass holders/groundglasses.


Pro focusing aid

A new leather bellows with an integrated loupe for perfect framing (overview over the full frame) and focusing (4x loupe) with the ALPA screen/groundglass. Small, light, versatile and robust - the optimum choice for the demanding traveling professional.


Schneider-Kreuznach ALPA Apo-Helvetar 48 mm

Successfully introduced already at the begin of 2004: our exclusive Schneider-Kreuznach ALPA Apo-Helvetar 5.6/48 mm with Copal or Schneider shutters, image circle diameter 123 mm at f 22, 98 mm at f 5.6 - it has shown outstanding performance with classic film as well as with the latest generation of digital backs.
