Overview

The Novoflex CASTEL-M is an innovative solution for focus stacking at magnifications between 1:1 (lifesize) and 5:1. To create the best possible composite photo, precise overlapping of the individual images is of paramount importance. At the heart of the CASTEL-M rack is a spindle which moves the camera platform forward with extreme accuracy for each image, and which also includes pre-set indexing ranges for magnification factors of 2:1, 3:1, 4:1 and 5:1, movement being controlled by the large wheel at the end of the rack. Simply select the ratio using the lever on the focus wheel cylinder, set the start point (the drive can be disengaged to do this), and then rotate the wheel by click stops until the end of the sequence. Calculation of the increments is done automatically. The click stops have been calculated in such a way as to avoid the negative effects of lens diffraction, and are calibrated for full-frame (35mm) sensor cameras with attached lenses at an aperture of f4. Cameras with APS-C sensors can be used reliably up to 4:1, and Four Thirds to 3:1. Free control of the rack is also possible, by referencing the laser engraved scaling on the edge of the rack without engaging the click stops. Each rotation of the focus wheel moves the camera block 0.8mm. For use in product photography, the CASTEL-M can be fitted with the CASTBAL-PRO bellows attachment. In this configuration, the stacking steps are performed by moving the rear bellows standard, which means that the position of the lens does not change in relation to the subject. Compared to the classic Schleimpflug method, this creates front to back sharpness across the entire image field, rather than only in a single plane. Like all other CASTEL racks, the CASTEL-M is fully integrated into the Novoflex Q= system of Arca-compatible accessories.
