Spyderlenscal offers a fast and reliable method for measuring the focusing performance of camera-lens combinations. Photographers achieve razor-sharp images and can check whether their lenses are functioning optimally. This device is compact, lightweight, and durable, featuring a built-in level and a tripod thread.

Autofocus has been a practical aid for photographers for over 25 years. Especially when time is of the essence, this great invention is invaluable. However, there are also downsides; photographers have complained for years that the autofocus system can sometimes be inaccurate and unreliable. As a result, the first step after a photo shoot often involves deleting all images where the focus was not set correctly. This can be due to motion blur, but the most common cause is an autofocus error. This problem is often attributed to the camera selecting the wrong object or focus point, but another possibility is that the autofocus function of the lens may be incorrectly set.

If you are photographing a flat object vertically and find that it is not as sharp as it should be, this cause must be considered. Newer DSLR cameras feature autofocus correction functions that allow you to store the correction values of your lenses in the camera. This feature is being integrated into more and more cameras and will soon be available in other types of cameras as well.

Spyderlenscal precisely supports you in this autofocus correction process, allowing you to calibrate the respective camera-lens combinations and save the corresponding data in the custom camera settings.
