First of all, I want to say hello to everyone on the forum. My first post and don't mind if the topic is in the wrong place. I looked where I could open a thread and it seems fine here. I have a problem with the Kenko Auto Extension Tube Set DG for Nikon F Mount. The camera they use is Nikon D780 with a lens Nikon AF-S 24-120mm f/4G ED VR. The problem is in the autofocus when using focus stacking. .When each of the tubes is used separately, the autofocus works. But if I use two or all three tubes, it doesn't work. I have read a lot about the possibilities of why this is so. But I don't understand one thing. If I set only the 36mm tubes, the AF works. However, if I put the 12mm and 20mm tubes together, it doesn't work. The distance from the sensor is similar. The amount of light according to the sensor is almost the same. Contrast, too. Then why doesn't it work? When they are separate, each tube works. However, it does not work in any combination with 2 or 3 tubes. I would really appreciate an answer. And don't mind the English. Because I write to the user a little of my knowledge and google translator. -

There is no reason why a DSLR in live view can't act exactly like a mirrorless camera, e.g. the D780 to my understanding gives a very similar experience. -

With the D850, if you're in LV with EFCS then you only hear the shutter closing and opening again once. However, the D7200 doesn't have EFCS (the D7500 does). How Nikon implemented LV shooting in many of their early DSLRs was quite ... peculiar. But I can see that if the shot is to be made with the full mechanical shutter in LV then the LV has to be stopped and mechanical shutter closed before opening again. And implementation of EFCS probably requires functionality implemented in the sensor hardware. -
