DSLRKIT Lens Focus Calibration Tool Alignment Ruler Folding Card(Pack of 2)

Description

Instruction 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. Size:1912.3cm Package
Included: Lens Focus Calibration Card X2 Usage 1. Set up the ruler. 2. 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. 3. 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
QR-Code at the center of the ruler, then take a photo. 4. 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. 5. 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.
