[QUOTE="Paliswe, post: 804933, member: 48977"] Hi, just to be sure that I use the correct words, I looked it up in the English Z6 reference manual. In the menu, under Photo shooting Menu ("camera"), there is Focus Shift shooting and in the submenu you have "No. of shots" selectable between 1 and 300, then you have "Focus step width" selectable between 1 and 10. Just for clarity I will call the focus distance between two shots for - focus distance (!). I may have been unclear on that. Sorry about that. I don't think that the camera makes any calculations. It just performs the settings done in the menu. Take one shot - shift focus distance two steps (or whatever between 1 and 10) - take next shot and so on until all shots has been taken or infinity is reached. What I wanted to say in my post #18 is that the focus distance vary depending not only what "Focus step width" you choose, but also what lens you are using. In the two pictures I have enclosed, my focal length is 200mm, picture taken from 4.15 m distance to "zero cube". While one of my lenses (70-200) shifts focus distance about 20-30 cm at 4.15 m, when the focus step motor makes 20 steps (10 frames x 2 step width), the other (24-200) under the exact same conditions shifts focus distance about 80 cm.
