Camera Lens Focus
Calibration Card AF Micro Alignment Ruler Folding Chart
|
Description:
- 100% brand new and high quality
- Features:
This compact ruler allows you to determine if your lens is auto-focusing
accurately as it should. It is an essential tool that is particularly useful
when shooting with a shallow depth of field, where focusing should ideally be
"spot on".
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.
- How to use:
Set up the ruler.
Ensure both the camera and ruler are level, exactly perpendicular and at the
same height. It is best to mount the camera on a tripod to do this.
Set the lens to the widest aperture to obtain the shallowest depth of field.
This will make it easier to determine if your lens is focusing accurately.
Auto-focus on the crosshair at the center of the ruler, then take a photo.
Inspect the photo to see if focusing is accurate. It is recommended that you do
this on a computer since you will be able to see better on a bigger screen. If
focusing is accurate, the '0' on the ruler should be the sharpest point on the
image and the other numbers get blurrier as you move away from the 0.
If any number above the 0 is clearer, then your lens is backfocusing. Otherwise,
if any number below the 0 is clearer, then your lens is front focusing. In
either case, you would have to set the auto-focus micro-adjustment parameters on
your camera body until you are able to obtain a picture that is sharpest at the
'0' on the ruler.
