The main problem I am having is that I get no apparent change in focus when changing the AF-FineTune Saved Value?? Well, the AF fine tuning system is not that smart to be able to cope with all these variables and therefore calibration values might have to be different at various focal lengths, apertures and camera to subject distances.

The third method is to use an automated/semi automated software calibration tool that can save you time and possibly yield better results. I used an alignment fixture stand to fix my D750 to be parallel and the lens to be perpendicular to the target in the Z-axis.. Despite all challenges, I still highly recommend to play with the AF adjustment feature on your camera and learn how to properly calibrate your camera gear. If you find that from time to time your camera autofocus isn’t quite as accurate as it should be it may be time to have your camera and lenses calibrated. Because calibration can only be done for a certain focal length (on some lenses with a severe case of focus shift, I would recommend to even pick a single aperture to fine tune), which focal length would one pick to fine tune? I tested both lenses at various apertures and got dead on accuracy and repeatability. AF Fine Tune currently only writes one global value per lens. It showed good sharpness at between 5.6 – 7.1 and just average at 8 and 9, dropping precipitously into the “below average” category at 10 and smaller. All manufacturers have their own naming conventions, partly because it might be the technology they developed and patented themselves, and partly because they just want to be different.

The software became increasingly popular on Nikon cameras lately, thanks to the whole Nikon D800 Asymmetric Focus Fiasco, because it can clearly show which focus points are accurate and which ones are not, as shown in the below image: Here is the process of calibration using FoCal Pro (the software package we recommend): If you have a Nikon DSLR, you will have to use the Manual Setting Change (MSC) mode, where the software will tell you what to change on the camera and you will have to dial the values manually (until Nikon DSLR support becomes available in a future release), as shown in the following image: The cool thing about the FoCal Pro edition, is that it allows you to also find out what aperture is the sharpest on your lens and as I have already pointed out above, it can also analyze each focus point of your camera for precision. You can use this online Target Distance Tool (see below how to do this within FoCal) to suggest a suitable target distance for AFMA / Focus Fine Tune lens calibration with Reikan FoCal. While I was weighing the merits of the various methods of performing calibration — I have a 50mm 1.4D Nikkor that appeared to be less sharp than any of my other lenses, I just applied a bit of common sense to achieve a no cost solution. Using a third-party lens that may not be fully compatible with the camera. The test chart has been completely redesigned.
