LensAlign MkII Plus Focus Calibration System Instruction Manual
The LensAlign MkII Plus Focus Calibration System includes the LensAlign MkII and the LensAlign MkII Long Ruler Kit.
 
The Long Ruler Kit allows LensAlign to used at greater distances, and better accommodate specialized lenses, such as super-telephotos. It is comprised of a 32-inch, collapsible Focus Display Ruler, as well as a larger Focus  Target.
 
The LensAlign MkII from Michael Tapes Design is a precision reference tool that enables photographers to accurately measure and then adjust the auto focusing accuracy of their DSLRs.  It also measures the performance of the camera's manual focus system.
 
DSLR autofocus systems may not be as precise as you think! Manufacturing tolerances often result in subtle mismatches between camera bodies and lenses, and can impart poor auto-focus performance.
 
Most new professional and enthusiast DSLRs have an Auto Focus Adjustment feature. Using the exclusive and patent pending True Parallel Alignment, the LensAlignII verifies perfect parallel alignment between the camera sensor plane and the target surface, a requirement for consistent and precise Auto Focus adjustment.
 
LensAlign MkII comes standard with a 10.5" Focus Display Ruler containing 2 alternate display patterns (one on each side) and a 24" Long Ruler.
SKU: LA-LA2P
What is LensAlign™?
You're a journalist capturing the speaker at the podium...

You're a sports shooter targeting the chest of a speed skater...

You're shooting glamor up close, really tight DOF, and that lead eye better be tack sharp...


For any money shot, capturing that perfect moment is critical. They're all important photographs; sometimes there's only one chance to get them. So you don't want your focus system to let you down. You need that shot to be sharp—if it isn't sharp, you lose the game, the job and the next job.

Almost all cameras and lenses are mass produced. Any mass produced product, even very expensive DSLRs and high-end lenses, is designed and manufactured within certain allowed tolerances. The sensor and the focal plane, the autofocus mirror assembly and the focus sensor, and the myriad of other critical tolerances are not all perfect. In combination, these manufacturing tolerances can degrade accurate focus performance.

If a focus problem exists, before you can fix the problem, you need to accurately measure any focus deviation. Now you can.

LensAlign™ is a patent pending hardware-based tool for precision focus analysis of camera and lens combinations. Photographers and camera repair facilities can use LensAlign to determine if the focus system of the camera (auto and/or manual) is working properly with each and every lens. In other words, using LensAlign, one can assess whether a specific camera body and lens combination is capable of attaining the maximum sharpness for that pairing. Having a LensAlign system in your studio or home is like owning a factory-quality calibration system providing quick, accurate and repeatable results.

And now, when used with LensAlign, many of the latest DSLRs allow you to adjust the auto-focus for each lens using their menu accessible Micro Adjustment or AF Tune feature.

Precision and Certified
Some homemade solutions advise you to focus on a tape measure running away from you, the camera held at a 45 degree angle. But doing so will degrade the consistency of the camera's focusing measurement. Trying to autofocus on a single line on the tape measure, only a few pixels of the autofocusing system (which is just multiple pairs of linear pixel arrays) will be able to see the target. Ideally, the contrast in the reference target should cover the entire area of the camera's center focusing point, and the reference target should be perfectly parallel to the camera's focal plane. Additionally, precision focus testing requires the following:

  • The focusing target needs to be significantly larger then the focus point itself to account for focus sensors that are slightly off-center from the point indicated in the viewfinder display.
  • The plane of focus needs to be 100% parallel to the sensor otherwise the focus sensors can produce varied results.
  • The measurement of focus should occur as close to the center point of the image as possible to eliminate field curvature errors.
  • The measuring scale must be a straight and accurate device that can allow you detect your focus plane at a glance.
  • Measuring should occur at your normal working distance, or at a minimum of around 20x the focal length of the lens.

LensAlign is designed to achieve all of these criteria in a simple, compact and easy to use measurement tool. LensAlign PRO and LensAlign PRO PLUS are individually laser tested and certified for accuracy.

Fast, Accurate, Repeatable
LensAlign reduces setup time to a few minutes (just mount it on a tripod) and produces the exact same focus repeatability for each test.

Now, You Are In Control
In the past, the solution was to send your camera body and lens to the manufacturer to have them calibrated together. Often after doing so, when you purchase another lens, you find to your disappointment that the new lens also needs to be calibrated.

Shipping your body and all of your lenses to the manufacturer is expensive and time consuming. Having your own Focus Test System gives you the ability to make the adjustments you need to achieve precise focus, or to provide the evidence that the service facility requires to effect a repair or honor a warranty.
