Reikan Focal 2.0: Autofocus calibration for DSLRs via software
[09:27 Mon,9.November 2015 by Thomas Richter]
Not always the autofocus a camera lens combination is perfect - the resulting images will appear slightly blurred. Basic is then often a minimum discrepancy of the distance between the focal point and image / autofocus sensor. Sometimes slight variations in the production are to blame, sometimes deviations by the Daily use. Some DSLRs offer therefore the possibility to calibrate the autofocus subsequently but this is not very easy to accomplish. The tool "FOCAL" (Mac / Win) by Reikan helps owners of Canon / Nikon DSLRs in this process and calibrated automatically. PIC 2: Focal Setup To calibrate is a special graphics printed and DSLR camera connected to your PC or Mac via USB. Next, (directed by OnScreen Help) Camera correctly onthe test chart aligned. Then each of the tests (Schaerfemessungen at different aperture values, focal consistency) can be automatically executed, Focal shoots images, analyzes them and provides the basis of the determined data autofocus new one or are (depending on camera model) the AF correction value, which is then manually must be set. The new version 2.0 (free for all buyers of Focal 1.0) provides functions for comparing the test results with those of other users, more information about the test results (including lens profile graph) and voice instructions in aligning the camera. Is a prerequisite for the subsequent AF calibration, the camera micro-adjust the AF / Fine Tune function dominates - (here a list ofsupported cameras). FOCAL is offered in three versions, which differ greatly in their functions: the approximately 28 euro expensive standard version provides only the semi-automatic calibration, the 56-euro Plus version Additionally, the (fully) automatic calibration (for certain DSLRs ), the around 100 euros expensive Pro version provides all functions such as AF-consistency, aperture / focus and Dust analysis - and supports the only lenses with a focal length of more than 400 mm.
