IS FULL FRAME BETTER THAN CROP SENSOR?

Correctamundo! The best plan is to have at least one of each.

I have three cameras (yes, including my phone), each with their own sensor size,
Somewhere between really small and larger. I'd have to look up their sizes, if it mattered.
They take pictures that look great.

Crop is best because it is what I want.
FF doesn't cut it for me.

I'm surprised that very few "experts" mention the fact that DOF is the same, regardless of the focal length of the lens.

No he has it correct

At 10 minutes in he said; "I'll just show you one example, the same lens set at the same setting shot at the same distance. I'll put the same 50mm lens shot at the same f/2 on both cameras. The framing looks tighter on the crop sensor image due to the crop factor but shot from the same standpoint and the same f/stop both have the same depth of field." [my bold]

He is wrong -- fundamental misunderstanding of DOF (see illustration below). Also really dumb because to show how wrong he is he takes the FF image and crops it to match the crop sensor image to show the DOF is the same. Wow! In other words take the photo with a crop sensor and the DOF will be the same as in a photo taken with a crop sensor! Duuuuuuhhh! He also doesn't understand what bokeh is.

Really? You think he needs to take a Photo 101 class? Please provide a link to your professional web site so we can compare your images to his.

Also you claim he got DOF wrong. What exactly did he get wrong? Rather than just say he got it wrong, please be specific and explain what he got wrong.

Yeah, I know what you mean. My eyesight is getting worse, too.

The camera doesn't take pictures. It just records when the button is pressed. The nut behind the lens takes the pictures. if the pictures look great the credit goes to the nut. ;)

Probably because it's not. There's a common DOF fallacy based on an oversimplification of DOF as magnification and f/stop. Magnification is a function of lens focal length and subject distance. Therefore if you hold magnification constant (lot of camera movement) then the focal length factors out and so at the same magnification DOF is the same regardless of lens focal length. As I said, that's a fallacy.

Didn't you just contradict your premise?

The DOF is the same regardless of focal length.

No. I was explaining the common error people make. Read what I wrote.

Still, DOF is the same, regardless of focal length. The "common error" is thinking that the DOF changes with focal length. Saying it's a "common fallacy" doesn't prove your point. I could post references - maybe later.

No it is not. I said that's a common fallacy. DOF does change with focal length (even when magnification is held constant).

Make/take.... create/record.
