Datacolor Spyder LensCal

Datacolor SpyderLensCal 

SpyderLensCal offers a fast, reliable method for measuring the focussing performance of camera-lens combinations. Photographers get razor-sharp images and can check whether their lenses are working optimally. This device is compact, lightweight and durable, with an integrated spirit level and tripod thread.

The problem:
For more than 25 years, autofocus has served photographers as a practical helper. Especially in situations that require a quick reaction, this great invention is a joy to use. But where there is light, there are also shadows, and photographers have been complaining for 25 years that autofocus is sometimes inaccurate and unreliable. The most common cause of this is an error in autofocussing. This is often explained by the camera selecting the wrong focus point on the subject. However, there is another possibility - one that is reluctantly considered, especially when you consider the initial cost of a high-quality lens: the autofocus function of the lens could be set incorrectly. When photographing a flat object vertically, if it is found that the image is not as sharp as it should be, it is necessary to consider this cause.

The solution:
Current DSLR cameras are equipped with autofocus correction functions. This option now makes it possible to save the correction values for lenses directly on the camera. This function is increasingly being integrated into cameras and will certainly soon be available on other camera types as well. SpyderLensCal precisely supports this autofocus correction process to perform the calibration for specific camera-lens combinations and store the corresponding data in the camera's user-defined settings.

Features: 

• This quick, easy solution for interchangeable lenses and DSLR bodies provides razor-sharp images by fine-tuning the autofocus function of modern DSLRs. 
• Compact, lightweight and durable with an integrated spirit level and tripod thread - the most convenient way to customise your camera equipment. 
• Save time and hassle by not having to send your equipment to a service centre. Now you can check and calibrate your lenses yourself. 
• Accurate and repeatable calibration of lenses and modern DSLR bodies. 
• Valuable investment to ensure that the camera controls the focus of the lens as accurately as possible. 

Requirements: 

• DSLR or other camera with function for saving lens autofocus corrections.
• Autofocus lenses suitable for the camera.
• No operating system requirements, as the tool communicates directly with the camera menu.
