There is nothing in what I have said above that you could possibly disagree with.
With the greatest respect bud, you need to go right back to the basic concept of DoF, its relevance, and how it is applied.
The DoF might be as you describe, but in moving back you have changed perspective so the two images are not the same. To get a like for like comparison, you need to adjust focal length from the same viewpoint.
No, seriously, don't. You are completely mistaken.
Funny how you keep moving the goal posts and simply will not accept that you are, what's the word...
wrong
I understand what's going on and I've been clear in what I've been saying, the problem is that you wont accept it and keep moving the goal posts to suit your own wrong view.
Remember how we got into this? You keep insisting that DoF changes with sensor size. It does not.
Change ONLY the format size and DoF is the same.
Take two cameras with different sized sensors, mount the same lens or a very similar lenses on each and take a shot from point A at an object at point B and the DoF is.... THE SAME. That's always been my point but you wont see it and keep insisting upon changing position and / or lens too.
Moving position or changing lenses does not prove that DoF changes with format size because you've changed other things. Good God, changing lens or position between two shots while using just one format will make the DoF look different between shots so what hope have you got of proving anything when you do this?
The way to prove that format size affects DoF is to change only the format size and see if the DoF alters.
It does not.
Therefore the statements.... Sensor size changes DoF, the smaller the sensor size the less control you have over DoF, you can't get shallow DoF from MFT are not strictly true, any of them. Sensor size in itself and by itself does not affect DoF. All you are doing is effectively cutting pieces out of an image so affecting DoF should be impossible, and it is. You have to change other things than the format size to get the DoF to change.
Anyone with two cameras with different sized sensors that'll take the same lens or similar lenses can prove this to themselves within minutes so how we can spend weeks arguing about it I simply don't know.
Do the test and convince yourself.
Anyway, you're repeated goal post changes and refusal to do the test yourself are confusing me as it's easy to do. Do the test and find out for yourself. It's simple to do.
Proved!
And as minds are closed on this easy to prove to yourself matter and those who will not see don't because they refuse to see that's my last word on this topic except ... "Try it and prove it for yourself!"
