Novoflex Auto Step Motor Rail System | CASTEL-MICRO

Novoflex CASTEL-MICRO is a stepping motor controlled focusing rack for use in a wide variety of applications in the fields of photography, measurement and science.
CASTEL-MICRO is the solution when conventional photographic equipment or internal camera functions reach their limits. It's ideal for focus stacking in macro photography, for example to capture images of insects, minerals and scientific documentation, etc.
Automated rail movements make focus stacking precise and effortless
Mount your camera and lens to the CASTEL-MICRO and initiate the stacking sequence with one click
Add CASTBAL-PRO bellows and PRO-APO-DIGI lens for shooting small and large objects with virtually unlimited depth of field focus
Achieve up to 50X magnification by using microscope lenses and MICRO-TUBE extension

The problem is well known: as the magnification factor increases – usually above 2:1 to 50:1 – manual focusing with a focusing rack becomes impossible. In addition, automatic functions, such as the internal camera function of focus bracketing, are no longer of much use.
The consequence is that photographs with such magnification can only be captured with an enormous amount of effort.
The solution is the CASTEL-MICRO with its specially designed control unit and four different control modes.
Step and Picture modes are quick and simple to use. In these modes either the step distance or the number of shots can be specified depending on the magnification factor and the aperture of the lens. The software then automatically calculates the number of shots or the step distance required. In addition, pauses between the shots can be taken into consideration, for example for mirror lockup in SLR cameras.
Continuous mode is available for special applications in which the sliding block is in constant motion so that there is no need for acceleration and stopping distances and any associated pauses. Exposures are then best done with very fast shutter speeds and/or a flash.
Bellows mode is designed for use with the optional bellows attachment CASTBAL-PRO. Adjustment at the front or back can be selected. The Bellows mode is not only ideal for macro photography but also for those fields of photography requiring much effort, special cameras and tilt and shift lenses. The BALPRO adapter system enables the use of various cameras and lenses. For example, it is possible to integrate high-quality, mechanical lenses used in specialist cameras into a modern stacking workflow.
The Bellows mode imitates the software control of the autofocus of a lens in order to produce a stack of images with different focus points of one and the same object. The stack of images is then processed by stacking software to produce an image with an astonishing depth of focus.

The control unit is powered by rechargeable batteries (Canon LP-E6 - not included in the scope of delivery! We recommend the use of original Canon batteries only!) and is thus ideal for outdoor applications and fieldwork. For studio work the control unit can be connected to the mains with the supplied AC-adapter.
The CASTEL-MICRO has a maximum travel distance of 100 mm and its smallest repeatable step distance is 0.2?! The maximum carrying capacity for vertical assembly is 4 kg.
CASTEL-MICRO can be fully integrated into the Novoflex-Q System with tripods, racks, brackets, etc. for complex set-ups. A camera is attached by means of the Q=MOUNT quick release unit, which is ARCA-compatible and can be offset by 90 ? if required. On the underside of the rail, the focusing rack has the ARCA-compatible dovetail profile over the entire length and can thus be used in compatible coupling units. In addition there are 2 standard 3/8"-16 and 1/4"-20 threads.
Camera coupling plates (ARCA-compatible) are available separately.
Camera release cables are available separately for the following systems: Canon EOS, Fuji, Nikon, Olympus, Panasonic, Pentax, Samsung, Sigma and Sony.
Other cameras on request.

As photographers strive for the best possible picture, Novoflex develops and manufactures tools to support them. Tools that allow the photographic limits of the equipment to be blown and the impossible image to become possible. In the think tank of Novoflex ideas are thought out to make the perfect tool for the perfect picture even more perfect. Virtually all products are developed by our photo-practitioners and designers and produced in our production facility in the Bavarian town of Memmingen.
