50x is the common vendor recommendation (if you have to fight your case) but I found that 25x roughly gives the same results for the given problem. 25x (3 sheets) or 50x (12 sheets) the focal length. This gives you a target roughly appropriate to test at a distance of approx. Inkjet is better but laser does ok if illuminated from the sides. Note: Print out 3 or 12 copies if using 8x11' or DinВ A4 paper, then cut away the blank borders, then glue a row of 3 sheets (in portrait orientation), or two rows of 6 sheets (all in portrait orientation) resp., onto a wall or board. Print out the target image (FoCal_MultiFocus_Target_1r1ns.pdf (or. So, you only should need to pay once even if shuffling bodies ) Purchase (or update) FoCal Pro 1.6+ ( Note: you can register for up to five camera bodies and change registration up to 10 times. I didn't notice any significant issues though. Some people have reported issues to get version 1.6.0 to work properly. The following is a best practice method which I also had in mind when working together with Rich to make version 1.6 happen.

In the following, I am going to describe how to use this software for the given task and what results to expect. This version and its features are described here:

If you're already a customer, you need to update to version 1.6.0 (or later). If your camera is affected by the defect, ask Nikon for a refund to make them feel guilty at least ) After all, they claim that only a small number of D800s are affected which definitely is a false statement (only explained by the fact that most customers don't return their camera in lack of a procedure to reliably fix the defect or exchange for an unaffected one). It currently sells for 70В GBP (cheaper versions are available but they lack support for the array test).

In order to check the full sensor array you'll need the Pro version as it includes the Multi Point Focus Test tool ( ).

Note that I have no benefit in making this statement but the purchase of FoCal Pro was the best purchase I did in a long time.ДЇoCal is an automated software which via USB determines the optimum AF manual adjustment (AFMA) aka AF fine tune parameter for a given lens. I fully endorse the FoCal software and Rich deserves any support from us so he can continue to make his software even more powerful. In order to make the testing procedure published in the article cited above ( /lumolabs/articles/D800Focus/OuterSensors.html) as automated, meaningful and quick as possible, Rich (the author of Reikan's FoCal software) and myself decided to work together and enable buyers of SLRs to check their cameras if in doubt. Last but not least, the protocol from this method may be a good measure to preserve the value of early D800 on the used market place. Maybe, Nikon could use our method with multiple lenses to document the performance of a camera after servicing for affected customers. Therefore, such a check may now be advisable with multiple lenses. There are more recent rumors that Nikon may meanwhile have dispatched a service procedure to more reliably fix the issue in service. Furthermore, without a statement from Nikon there remains substantial doubt that a camera 'fixed' in service (e.g., calibrated for every AF focus point sensor) performs as well as a camera which was manufactured according to standards in the first place. Especially as Nikon remained silent about the issue and returned many cameras sent to service 'as fixed' while further inspection revealed they're not. Unfortunately, such a check seems to have become suitable after it is now possible that many such cameras manufactured so far (Aug 2012) suffer from bad functioning left AF sensors. More about this has previousy been published here: In fact, this paper contains examples for two Nikon and one Canon camera.ДЄ main purpose of this paper is to check if a Nikon D800, D800E or D4 are working as advertized. It can be used for almost any camera with a phase AF system, i.e., SLRs and SLTs. This technical study describes a method for checking if a camera's entire AF sensor array works as advertized.
