The 2 new bars on the chart shows the results of our small focus changes. Wait for a new bar to appear on the chart, and then repeat a few times to see how things change: Pick a direction (it doesnвЂ™t matter which), and hit the single arrow вЂ“ so either the orange вЂњвЂќ button (focus moves away from the camera). The next step is to see how close to perfect focus we are. If this is a little confusing, keep reading as it should become clearerвЂ¦ Step 2 вЂ“ Focus in one direction The red horizontal line shows the level of the best shot so far. There is no scale, it just shows whether a shot is sharper (the bar taller), or not as sharp (the bar shorter) than other shots. This chart shows relative quality levels between the shots you take. The camera performed a focus operation, then FoCal measures the quality and shows the result as a blue bar (same as the Live View AF button) on the chart on the right of the screen. When Live View is started, a measurement of the quality is taken and the first bar is shown in the chart, as shown in the example above. When the test is started, it focuses and take a shot. Read the second below on Lens Focus Hysteresis for an explanation of performance on older/lower quality lenses) Step 1 вЂ“ Start the Test (Note that this example is with a well-behaved lens. HereвЂ™s an example of how the utility can be used. The utility takes measurements of the sharpness of the image, and allows you to control the focus position and watch the changes so you can find the best focus.

HereвЂ™s an example of the screen a few seconds after hitting the Start button: Hit the Start button and in a few seconds FoCal will get information from the camera and show you a zoomed live view image.

When you open the utility, youвЂ™ll see a window similar to this:

If you have not run the Target Setup utility before starting the Aperture Sharpness test, FoCal will warn you and give you the opportunity to use Target Setup:ДЄlternatively, you can manually open the Target Setup utility in Aperture Sharpness test mode by clicking the Target Setup link on the Status tab Control panel from within the Aperture Sharpness test, or clicking the Target Setup button on the bottom bar of the test. Take a look here: MultiTest Opening the Aperture Sharpness Target Setup utility Note: MultiTest вЂ“ new for FoCal 2020 вЂ“ removes the need for this вЂњpefect focusвЂќ step and gives more information about the aperture profile of your lens, including focus shift information.

Further information on this functionality is available at Target Setup Overview. ItвЂ™s important to ensure the standard Target Setup checks pass appropriately as well вЂ“ you can see this if you select the Check panel on the right side. To assist with this, the Target Setup utility вЂ“ when started from within the Aperture Sharpness test вЂ“ offers extra functionality. The Aperture Sharpness test only produces representative results if the camera lens is focused as well as possible on the target. Whatever you do check the results at the range you are shooting at and if not correct be prepared to reset to zero (or your previous setting determined by whichever method) if you will be happier with that situation.Target Setup Utility вЂ“ Aperture Sharpness Good luck, it is well worth doing but the day before might be a bit ambitious!

I think if you are sure the target is correct you can just tell the software to continue but loose the function that tells you if you nudge the camera off line during adjustments, not a problem if your body will run full auto, you can just go sit down out of the way until it is done. I think with my 500 I could just get far enough away that the whole of the target was covered by the sensor, if it is not I think that causes problems too, I think I just about managed to get on the infinity setting with my 200. Check you have enough light according to the instructions then add some!

I found that the target verification was doing the same to me, I had drawn lines on my workshop floor and put a plumb line from the bottom of my tripod to get in line, so I was pretty certain it was spot on, had all sorts of arrows, up down slew right move left, no idea where to go, added some light after reading what the ideal exposure was, then added more light, and hey presto big green tick.
