Product Description

LensAlign MkII is a precision reference tool that enables photographers to accurately measure and then adjust the Auto Focusing accuracy of their DSLRs. It also reveals the performance of the camera's manual focus system. A few years ago, photographers started to notice front/back focusing problems with their DSLRs. For example, when their camera's AF system was locked on a person's eye, the person's nose or ear was actually the sharpest part of the captured image. In order to allow hundreds of lenses and bodies to be interchangeable, the tolerances within the manufacturing process can cause any specific body/lens combination to potentionaly exhibit these front/back focus anomalies. To compensate for this condition, most new professional and enthusiast DSLRs have an Auto Focus Adjustment within their menu system. LensAlign was created as a focus system measurement standard by which photographers can accurately measure and improve the performance of their cameras' focus systems. Like its industry standard LensAlign PRO predecessor, the LensAlign MkII features our exclusive and patent pending True Parallel AlignmentTM (TPATM). TPA verifies perfect parallel alignment between the camera sensor plane and the target surface of LensAlign, 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. A 24" Long Ruler add-on option will be available in early February. LensAlign MkII is shipped flat in a Priority Mail postal envelope to reduce shipping costs. The MkII can also also be disassembled for travel or storage. Note: Ships flat. Simple assembly required. (Under 5 minutes with no tools).

The LensAlign Focus Calibration System (FCS) works effectively for digital cameras with microfocus adjustments. What you're not told is that you'll also use 1 or 2 tripods, a computer with web access, a tape measure, and a copy of Photoshop.

Use is not complex once you get the hang of it. Unfortunately, you will have to go to Tapes' website and search for usage instructions. There is nothing provided with the product, an inexplicable omission. Even when you get to Tapes' website, you'll have to search around a bit to find the procedural instructions. His "knowledge base" under the support tab has 28 articles, which is a bit confusing. The one you want is [...]

In a nutshell, here's how the thing works:

(1) Assemble the FCS.
The FCS arrives in knockdown form, with stiff plastic pieces. You'll be able to set it up in a couple of minutes, using the precise instructions provided. They're of the insert-tab-A-in-slot-B type and well illustrated. You'll be wondering why, given that it consists of a few stiff plastic pieces, it cost as much as it did. The key features are a focus target with a hole in it that shows a red dot behind when things are lined up, and a tilted ruler on the side of the focus target that has calibration numbers extending forward and backward from the plane of the main focus target. The red dot and rigid structure after assembly ensure the ruler is perfectly square to what your camera will be focusing on.

(2) Figure out how far your lens needs to be from the FCS to run the test.
This varies by lens focal length, aperture, and camera sensor size. You'll have to consult the website to get the formula, but once you're there Tapes provides a handy calculator. For example, with a full-frame camera like a Canon 5DM2 using a 200mm f/2.

I decided to order the MkII Focus Calibration System to hopefully help me solve some focus issues I have been having with my Canon system. A few thoughts on the MkII:

1. It does not ship with any usage instructions. The only instructions it comes with are for assembling the device. Instructions for use can be found on the LensAlign website, but given the price, a simple printout of the basic instructions would be appreciated.

2. The device is small, much smaller than I had anticipated, which makes it small in the frame. I would think that making the focus target larger would yield more consistent results. I purchased the MkII primarily to help calibrate my 400mm f/2.8 lens on both of my camera bodies. Given that the instructions from the website recommend the device be places at least 25x the focal length of the lens to calibrate, that puts the device quite a distance (minimum 35 or so feet) away, which makes it quite small in the frame. I had trouble getting repeatable results as the autofocus would sometimes focus on the front edge of the ruler rather than the focus target, even though the selected focus point in the camera was centered on the focus target. A larger focus target would probably help solve that type of issue.

3. The device is a very good design. I hadn't considered the need to align the planes of the target and the camera sensor during earlier focus adjustment attempts, and this devices does that rather cleverly. It may take a bit of time to get things aligned, but it works quite well.

4. In the end, the device did, I believe, help me isolate and address some subtle focus issues in my system, but not without some trouble with the longer lens. A more substantial focus target seems like it would help the MkII give more consistent results. Documentation on either Amazon or the LensAlign website doesn't mention inability to use the MkII with long lenses.

Note: See updates at the bottom of my review.

This is good tool to calibrate your lens but as far as instruction and support goes it's lacking.

The only supplied documentation is a sheet on how to assemble the device but absolutely nothing on how to use it. (I purchased LensAlign MkII version).

On the package there is a reference to the website. If you spend enough time here, you will eventually find 3 videos and some PDF documents to assist with the calibration process. The layout and structure of the website is a lacking in many ways:

1. There is no logical structure to the content. Be prepared to spend a little time and become a little frustrated.
2. Once you finally find some content you can't bookmark it because the URL is the same as the home page (very odd)
3. If you find the page of PDF documents, there is a chance the illustrations and information in those docs don't match your specific version. Plus some of the instructions are weak and is lacking information.
4. Beware: On some web pages, you may experience that you can't scroll all the way down on a page preventing you from accessing all the content. The vertical scroll bar is maxed out. This was a problem on Firefox v11 but wasn't as bad on IE v9.

Now if adequate instruction was included in the package, the above wouldn't even be issues.

Once you educate yourself from Michael's videos and PDFs and watch some 3rd party You-Tube videos you should be able to come up with a process to successfully calibrate your lens to a body. Keep in mind this will take some figuring out on your own and a little web research. For the price of this tool, its not asking too much for adequate instruction.
