- You can use this ruler to determine how "off" the focusing is for a particular camera / lens combination and, on supported cameras, adjust the camera's auto-focus settings to resolve this
- On Nikon cameras, this feature is known as "AF Fine Tune". On Canon and Sony cameras, it's known as "AF Micro Adjustment". Please refer to your camera's instructions manual to see if this feature is present.

## Questions & Answers

**Q: How far away should the lens be away from the card?**
A: It really depends on the focal length of the lens.  You want to try to fill the frame as much as possible with a photo of the card.

**Q: What do you focus on to calibrate your lens?**
A: Focus on the center target.  The plane at which the side graphics are sharp will indicate front or back focus, relative to the center target.
