What is LensAlign?
How does LensAlign work?
How to use it.
Bring your lenses back to life.
DSLR autofocus systems may not be as precise as you think. Manufacturing tolerances often result in subtle mismatches between camera bodies and lenses, resulting in poor autofocus performance. This can cause your images to be softer than they should be. Every maker of hi-end DSLRs acknowledges this by providing auto-focus adjustment capabilities right in their camera’s menu systems.
LensAlign MkII is the proven solution that offers accurate and repeatable calibration for each of your lenses. Photographers can use LensAlign to determine if the auto-focus system of their camera 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. And if not, LensAlign is the premiere solution for determing the best setting in your camera's auto-focus adjustment menu.

Introducing the 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, collapsable Focus Display Ruler, as well as a larger Focus Target. The Long Ruler Kit can be purchased as part of our new LensAlign MkII Plus system, which includes a LensAlign MkII along with the Long Ruler Kit. It can also be purchased seperately and added to any existing LensAlign MkII.
Now, you are in control.
Now, You Are In Control
In the past, the solution for mis-matched lenses was to send your camera body and lens to the manufacturer or repair facility to have them calibrated together. This can be expensive and time consuming. Having your own LensAlign MkII gives you the ability to make the adjustments you need to achieve the full sharpness your lenses are capable of.
LensAlign MkII Plus
LensAlign MkII is a Focus Calibration System that uses your camera's menu-based AF fine-tune function to match each of your lenses precisely to the camera body. You no longer have to settle for out-of-the-box performance from your lenses. You can now make them as sharp as they can be.
Two precision componants in a unified design gets you sharper pictures.
When you look at LensAlign you see two parts; the Target on the left and the Display Ruler on the right. Your camera focuses on the left, and you view the error on the right. It's that simple. Finally, you are actually able to know for sure. No more second guessing your auto-focus, because LensAlign shows you the extent and direction of the error. Simple, fast, ingenious.
Your camera becomes part of the solution, not part of the problem.
With the information from LensAlign, you are now able to input this data into your camera's menu system and actually optimize your auto-focus system for each individual lens. Each time a lens is mounted, your camera will automatically use the AF adjustment value for that lens, giving the system the ability to focus to its full capability. You're assured that your camera and lenses are working in harmony, delivering the sharpest possible images. Almost all hi-end DSLRs have this capability.
True Parallel Alignment™
Our exclusive and patented* True Parallel Alignment™is the cornerstone that provides visual verification of perfect camera positioning during AF calibration. The orientation of your camera is essential for accurate analysis and adjustment of the camera’s auto-focus systems.
Only LensAlign meets all of the following requirements for precision testing and adjustment of auto-focus systems.
• 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.
• Testing should be done at your normal shooting distance for a given lens, or at a minimum of around 25x the focal length of the lens.
LensAlign is simple, compact, and easy to use.
Setup requires only few minutes. Just mount LensAlign and your camera on tripods. aligning them using LensAlign's exclusive True Parallel Alignment will produce the exact same focus analysis and adjustment value for each test.

1 - Setup LensAlign and the camera to be tested
Mount the camera/lens combination to be tested on a tripod. LensAlign can be table-top or tripod mounted via its 1/4-20 tripod socket. Set the test camera’s aperture to ƒ8. Looking through the test camera’s viewfinder, adjust the camera’s position so that the center "sighting port" of LensAlign is approximately aligned with the center autofocus point of the camera.
2 - Sight the camera to LensAlign
The goal of alignment is to adjust the camera’s position until the hole in the Rear Sighting Plate “Bullseye” is centered in the center sighting port , and both are centered in the frame. When this is achieved, the Focus Target of LensAlign and the camera imaging plane will be perfectly parallel, which is required for accurate focus evaluation. (Note that only the center Sighting Dot will appear centered when perfect alignment is achieved).
Pro version shown. MkII works same way.
3 - Capture test images
Set the camera to Manual or Aperture Priority exposure mode and open the aperture of the lens to its lowest ƒ stop (aperture wide open). Focus (using center-point auto-focus) and capture test images.
4 - Evaluate test images
Review the test captures on screen and evaluate the results as displayed on the Focus Display Ruler. If the test camera has Auto Focus Adjustment capability, set it appropriately to correct any auto-focus errors that you may observe. If necessary, repeat steps 3 and 4 until proper focus adjustment is achieved.
