Hello Jochen
There may be a language issue here but it would be a whole lot worse if I was to try and help in anything other than English!
Just so that we are on the same wavelength, my understanding of the term Hyperfocal is that it is the closest focusing point for a particular lens/sensor combination, at a given aperture, that also enables objects at infinity to be acceptably sharp.
There are plenty better explanations on the internet but hopefully this covers what you are trying to achieve but, if your furthest required “in focus” distance is less than infinity, it will the same principles but with a modified technique.
I can see from your screenshots that you are using an IQ3 50mp sensor and SK 150mm lens at f10.
According to the Lumariver DOF app (at my C of C settings) the Hyperfocal distance for an SK 150mm Lens at f10 on the your sensor is 166 metres. Which will then give everything from 83.2m to
in sharp focus.
You are using the Calibration tool on the XF and have taken 5 frames at 5 MCU intervals and you should be looking at which of those frames has
in sharp focus or is the closest to having it sharp.
The sequence you show (and asked whether it is correct) looks right to me - with the middle one (29) being your selected focus point to test.
You then have two focused further away (24 & 19) and two nearer (34 & 39).
It is at ,this point that I’m not sure I understand your question so please forgive me if my explanation below is irrelevant to you but I’m hoping it might help.
In your second test shots I can’t really see whether you have anything at
in your shots (which may be a problem as
is almost as far away as eternity
).
If you do it’s then just a case studying the points of focus in each frame and, if none of them are achieving sharp
, it’s just a matter of deciding which direction you need to go with your trial focusing - by increasing or decreasing your MCU - and then repeating the process all over again and shooting the 5 test frames. Until you find the one that gives the result you want.
It is your judgement that counts here and the XF will not decide the HF point for you. Infinity is almost certainly not going to be at 0 on your lens (it isn’t on any of mine) so don’t let that confuse you.
Once you have found the MCU that gives the focus depth you want, it’s then just a matter of saving that value from the hyperfocal calibration tool. And then, if the HF focusing icon is selected, it will go back to this focus point every time for this lens. And it will be spot on if you have calibrated it correctly and are using the same aperture.
The XF is a great tool and has so many useful functions that it takes a while to get to know them. But it is worth the effort.
I hope that this helps.
Paul.
I wrote this before reading your last post so there is some unnecessary explanation above. Sorry.
