It is not “our” standard.

Imagine if I started a thread about 2 lenses to see which is sharper. Using your exact setup I took 1 picture with each lens. Instead of focusing on the car (which is what you would want the focus on because that is the closest object to your setup) by either using manual focus, or having the focus box on the car I simply let the camera pick focus and the camera picked something else to focus on behind the car with both lenses. Now imagine if you said to me that this experiment is useless because to see the sharpness, I should have focused on the car up front. Instead of realizing that I made a mistake, I kept coming back and said “but” “but” “but”.....

My test would have proven nothing.

You don’t test bokeh at f18. You test it at the widest aperture. Whether that is f1.4, or F5 as it is in this case.

This is very basic stuff and since you know the word “BOKEH” you should have at least known “how” to test for it. You will never find another test by another person like yours who understands at least the minimum.

That is why this test was useless.

The “only” time you use F18 is when you DO NOT want bokeh.

Based on your user name, I’m going to guess that you cook for a living. Imagine a supplier brought you 2 cuts of meat but he trimmed all the fat away already. How can you tell which cut was leaner?

said earlier: I don't think anyone is against experimenting. But, when you've said you've demonstrated bokeh via these posted examples, everyone with half a clue of the topic has replied essentially: no, you haven't. I spent some quality time giving some actionable feedback on what to change if bokeh was what you truly desired to achieve given your equipment. This is a different experiment from comparing the sharpness of two lenses. Ron gave some actionable and demonstrated tips in that area. If you're unsure of what specifically you were trying to do ... those are the experiences maybe best kept to yourself...

also said earlier: Your use of a narrow aperture does show the background out of focus behind the subject. But, "Bokeh" is a subjective and qualitative assessment of the completely out of focus aspects of the background rather than only slightly out of focus. You have a good color selected for the background, but neither of the background elements should be there (no vase, no panda, preferably no shadows). Rather, the background should be empty and the wide aperture used to completely blur all the details.

If you want to make your own definition, go ahead, have fun, it's a free country. But, don't be resentful of all the laughing ...

Well, if you want a scientific process, the simplicity of it astounding and not as ridiculous as you make it sound.

Experiment (anything) take notes. Repeat the experiment to verify the data (no limit on repeat as some areas will need refining). Present whatever to your peer for review.

So, if you want a full thesis on your ridiculous claim, go back to school.

This experiment was released too fast w/o verification. If this had been done several errors would have been avoided and the detractors would have been left with nothing to do but find another target for their trolling.
