Lens calibration is a series of small adjustments made to fine-tune your lensвЂ™ focus. If it isnвЂ™t, then itвЂ™s time to calibrate your lens. (If the lens is 200mm or over, reduce this factor to 25x.)ДЇor example, if youвЂ™re checking a 35mm lens, youвЂ™d calculate this distance 35mmx50=1750mm.ДЇollowing the same instructions given in the previous test (turn off image stabilization, put your camera into single-shot autofocus mode, use the center focus point, etc.), focus on the center object.Д¬heck your photo to make sure the focus is on the center object. Position your camera on a tripod approximately 50x away from this focal length. Note the focal length of the lens you want to check. Line up five identical objects on a flat surface at 45 degrees from you (batteries work well for this test.) If the focus is on their nose, itвЂ™s front focusing. If the focus has shifted over to their ear, the lens is back focusing. (Shoot tethered to your computer for convenience if you like.)Д¬heck to see if the focus on the subjectвЂ™s eye. Now, import your photo into Lightroom and zoom in close. Focus on your subjectвЂ™s closest eye and use a cable-release or self-timer to activate the shutter.

Put your camera into single-shot autofocus mode on a tripod, with your center focus point activated (because itвЂ™s the most accurate focus point.)
