For years, LensAlign MkII has been the proven Focus Calibration System preferred by hundreds of professional photographers for its simplicity of design and structural integrity. LensAlign uses your camera's menu-based AF fine-tune function to match each of your lenses precisely to the camera body. You don’t have to settle for out-of-the-box performance from your lenses. You can now make them as sharp as they can be. Now we are proud to announce a new generation of LensAlign, the result of our extensive research and testing with the latest AF systems on the market, using the latest calibration software.
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 premier solution for determining the best setting in your camera's auto-focus adjustment menu.
How it works...
Two precision components in a unified design gets you sharper pictures.
When you look at LensAlign you see two parts; 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 than 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 to 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 a 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.
