The MkII Focus Calibration System from LensAlign uses your camera's menu-based auto focus fine-tune function to match each of your lenses auto focus systems to your camera body for precise focusing. The MkII assembles into a system that offers a dual-sided focus target and a focus display ruler.
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 (or lack thereof) on the display ruler. 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.
The MkII is the second generation calibration tool from LensAlign and is built of sturdy card stock and 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 LensAlign MkII target features a front sighting plate with precision focus target and TPA sighting ports. The rear sighting plate on the target provides additional parts of the TPA sighting system.
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.
True Parallel Alignment is the basis that provides visual verification of perfect camera positioning during AF calibration. The orientation of your camera is essential for accurate analysis and adjustment of the camera's auto-focus systems.
The MkII system disassembles easily for storage and travel.
