SpyderLensCal provides a fast and reliable method for measuring the focusing performance of your camera with every lens combination. It allows photographers to have precise focus instantly or to check if their lenses are working at maximum performance. The device is compact, lightweight, and durable, and features a built-in level and tripod mount.

SpyderLensCal is designed to assist in correcting the autofocus system of our camera with multiple lens combinations and storing the settings within the camera itself. We support it vertically opposite our camera, photograph it with the widest possible aperture, and make minor adjustments to the focus while monitoring the photos. Without trying multiple times to achieve the correct focus, we use the meter provided by SpyderLensCal to add exactly the millimeters it shows us. And we are ready for the best shots.
