ALPA Focus Stacking Kit FPS/105 float

The ALPA Focus Stacking Kit is a complete solution for the highest level of performance and enables product and macro photography in previously unprecedented quality. The FPS/105 float kit contains the complete stacking unit, a high-end lens ALPA Macro Switar 5.6/105 mm float, the exceptionally universal ALPA 12 FPS and accessories. 

The included extension tubes allow a pull-out extension for recordings up to double life-size (2:1). The high-resolution lens itself can be used up to 4:1 thanks to the floating element.

The low-vibration focal plane shutter of the ALPA 12 FPS allows focus stacking with studio flash insert. The FPS can be operated without a mechanical shutter if the back is equipped with an electronic shutter and parking light. An unbeatable combination. 

The kit offers a discount of 11% compared to the single items. 


ALPA Castel-Micro
The new electronically controlled slider ALPA CASTEL-MICRO was specially developed for focus stacking in close-up and extreme macro photography, for example of insects, minerals, scientific documentation and much more.

The solution has a level of precision that is second to none. The slide itself runs on high-precision ball bearing guide rails to avoid any play. The ALPA CASTEL MICRO has a maximum adjustment range of 100mm and a smallest, repeatable step size of 0.2µ (0.0002mm)! The range of step sizes ranges from between 0.2µ and 100mm depending on the motif.

The maximum load for vertical mounting is 4 kg. The self-weight is about 1.4 kg. The control unit runs on rechargeable batteries (type Canon LP-E6 - not included) and is therefore also ideal for mobile use in museums and collections as well as in the field. For studio applications, the included power supply unit can power the control unit.

Four application modes are available via the touchscreen control unit:

The Bellows Mode
This mode is designed for use with the CASTBAL-PRO bellows attachment. This attachment is part of ALPA kits. Here the front or rear standard can be moved as desired. The Bellows mode is not only ideal for macro shots, but also for shots that were previously only possible with a lot of effort, special cameras or tilt/shift lenses. The BALPRO adapter system makes it possible to use not only ALPA cameras but also various third-party cameras and lenses. In this way, different components can be individually integrated for an optimal, efficient stacking workflow. The Bellows mode allows creating software controlled series of differently focused images of the same object, which is then processed by a stacking software to an image with an incredible depth of field.

The Step and Picture Modes
These two modes allow a quick and uncomplicated start. In both modes, the step size or the number of desired individual shots can be specified. This setup is based on the magnification and the aperture of the lens. The software then automatically calculates the required number of individual exposures or the required step size. Besides, waiting times between captures for swinging in and out can be set.

The Continuous Mode
This mode is available for individual applications in which the slide moves continuously, eliminating the otherwise necessary acceleration and braking distances and the associated waiting times. The exposures are then made with very short shutter speeds or in combination with flash.

The electronically controlled stacking solution is completely integrated into the ALPA system. It can also be combined almost endlessly using the universal dovetail profiles (UniQ/C standard).

For mobile use the control unit allows the use of Canon LP-E6 for power supply.
