The LensAlign MkII with FocusTune V4 Software from Lensalign includes the LensAlign MkII Generation 4 Focus Calibration System and FocusTune Version 4 Calibration Software for use with DSLRs featuring autofocus micro-adjustment. The MkII assembles into a system that offers a dual-sided focus target and a focus display ruler and works with the FocusTune software to provide accurate measurements and readings of the information.
The MkII is built of sturdy card stock and the display ruler of polystyrene, it assembles and disassembles easily for versatile long term use with any lens and with DSLR's equipped with auto focus adjustment capability. The 10.5" plastic Focus Display Ruler offers a choice of graphic display patterns on both sides (black with white numerals and white with black numerals) and is situated along the focus target at a 20º angle for optimized depth of field display.
To use, simply place the MkII on a table or use the integrated 1/4"-20 tripod mount to set the system on a tripod and with your DSLR on a second tripod, use the True Parallel Alignment feature to accurately align camera and target. With the aperture open as much as possible, focus your lens onto the target and see your lens's focus error on the display ruler. These images can then be used in the suite of tests included in FocusTune to provide you with accurate results.
Afterward, simply enter the data garnered into your camera's menu and it will adjust the auto focus to be precise and retain that information to be utilized each time you use that specific lens. This bundle includes license keys for both Mac and Windows and can be installed on 2 computers simultaneously.
