The problem:

Photographers have enjoyed the benefit of autofocus for 25 years now, but many still struggle with its accuracy and repeatability.

The solution:

Many newer DSLR cameras such as the Canon 5D MkII/7D /1D MkIV and the Nikon D7000/D300s/D700/D3s/D3x now offer a method to correct this issue: they allow you to store auto-focus correction data for several of your most important lenses

Requirements

• DSLR or other camera with capability to store lens auto-focus corrections
• Auto-focus lenses capable of being driven by this camera
• No OS requirements, as the tool works entirely within the camera’s menu
