Note that these are not uploaded with your results - they stay on your machine and are shown when you bring up a test from the history. There can sometimes be issues with handling failure cases e. This significantly speeds up the operation of the tests, even more so on older computers. Note that at the time of release, this information is basic and will be expanded shortly.

Click this to jump to a page on the website which has detailed information about the chart and how to interpret the information. You can connect to the camera either with the Connect to camera link, or click the No camera. But there are some significant external changes detailed below. For more details, the release notes post is available here. The majority of the time has been spent on internals, which means that operationally things are pretty similar to FoCal 2. Second, you will need to have been in your Included Updates Period on 1st October Pretty much everything.īut it grew into a complete restructuring of the inner workings of FoCal, including.

This is not available for Plus users - this is partly a perk for Pro users, and partly to reduce testing effort for pre-release software. I am not that enthusiastic about this lens, but now it is at least performing to spec.Another thing to get out the way early is who this is available for. I sent the lens to Nikon repair in New York and after spending more than $600 in additional repair, the lens performed much better on re-calibration. In re-testing fine tuning some time later, it was much worse than average with astigmatism off the chart. It had some impact damage which was repaired by the local Nikon approved repair service for more than $600. I also have the 80-400 AFS (second version of this lens). The lens quality was average, which indicates that I have a decent sample. Calibrating my lens showed that it needed a slight focus fine adjustment and that the optimal aperture was f/8, but results wide open at f/5.6 were only minimally different. I have the Nikon 500 f/5.6 PF, which is reputed to be quite sharp. It can tell you at what apertures the lens is sharpest and also how the tested lens compares to others of the same version in its data base. In addition to focus fine tuning, Focal also offers some lens testing and evaluation. They need to all be very close to the same value.Ĭlick to expand.I too use Focal and am quite satisfied with it, but have not yet updated to the 2.0 version. I might use FoCal to measure a value, then use use Dot Tune to see what values it provides, and then I will do some test shots even if it is just the "throw the tennis ball out in the grass" type testing to check the results. I like to use several methods to verify my AF fine tune accuracy. A 500mm lens with 1.4 TC takes at least 50 feet to calculate and I have difficulty finding a direct path in my house to make that work well. The process will measure a number of images along the -20 to +20 range so it will take at least 5 minutes to complete the test. Indoors I have found that I need to be certain that the target does not receive much outdoor window light that might vary during the testing. I have tried it outdoors but even on a bright day with no wind there can be enough change in the lighting to impact the results. If the lighting changes even a little the results become less confident.
What I have found with FoCal is that you need to be able to maintain consistent lightning to the target throughout the testing sequence. I find the results of my nikkor 70-200 f2.8 FL E lens to be spot on while my 70-300AF P to be much less so and I would suspect that is just due to the quality of the lens. The closer the results match the projected curve the better the "result confidence" is. The math teacher in me likes to watch FoCal work, it measures focus accuracy on the target at each setting and uses curve fitting to project the best focus value, it continues to check points and calculates the curve.

I use Focal Pro to do it's calculation then I shoot a series of images with the target to check focus accuracy. I built a FoCal target that incorporates the diagonal ruler. It does require some user intervention with Nikon cameras, changing the fine tune value between each shot. I use FoCal Pro and it works well for me.
