1- How do I start aligning my camera to LensAlign ?
90% perfect alignment is already achieved by means of Back-Sighting. Position yourself behind the LensAlign and place your eye directly behind the central hole of the Rear Sighting Plate. While viewing through both the Rear and Front Sighting Holes, adjust the LensAlign so that the lens of the test camera appears in the very center of the sighting hole. This should bring the cameras alignment very close to the proper position. Now all that is left is to fine tune the alignment. See next.
2 - How do I fine tune the alignment of LensAlign?
While looking through the viewfinder, determine the approximate state of alignment by observing whether or not the rear sighting hole (showing up as a white or black dot depending on lighting) is centered within the front sighting hole. Since the position of your eye with respect to the viewfinder eyepiece can alter the results, it is essential that for final evaluation you use Live View in magnified mode, or take a color picture and zoom way in on the picture.
If the rear and front sighting holes are not concentric you must move the camera slightly to bring it into alignment, always positioning the camera such that the central focus point of the camera is always centered on the central focus target of LensAlign. If the rear sighting dot is to the left, then move the camera right, and if the rear sighting dot is low, you must bring the camera higher.
Tip: Position a light above the LensAlign or use a narrow beam flashlight (torch) to illuminate the Back Focus Target to facilitate Front-Sighting. This helps with both the Live View and test shot methods of alignment.
