Manufacturer's Description

Solution Many newer DSLR cameras now offer a method to correct this issue: they allow you to store auto-focus correction data for several of your most important lenses. This feature is likely to become more common, and appear in other camera types. SpyderLensCal was designed to aid in correcting the auto-focus on your camera and lens combinations and storing them in your camera's custom settings.

Feature
SpyderLensCal provides photographers with a fast, reliable method of measuring the focus performance on camera and lens combinations. It allows photographers to obtain razor-sharp focusing, using modern DSLR autofocus micro-adjustment. The SpyderLensCal device is affordably priced, compact, lightweight and durable, with integrated level and tri-pod mount.

Benefit
SpyderLensCal allows photographers to easily calibrate their interchangeable lenses and recent DSLR bodies. There is no need to ship lenses and bodies back to the manufacturer any longer if you have the tools to do it yourself. Performing a Lens Calibration on each of your key auto-focus lenses can improve the number of usable shots from a day's shooting. And with a rugged, portable device such as SpyderLensCal, photographers can carry it on site or even on safari, so that lens calibration can be checked and adjusted if hard use or extreme weather may have caused changes.
