ecka84: Looks nice and sharp, but somewhat dull in terms of contrast and color saturation. Could be normal for m4/3 though. Can't see why it costs $600. Leica branding? This is more than 3 times the price of my EF 40mm f/2.8 STM.

Makes no sense.
Equivalence works. No confusion. No problems. Only too much ignorant people defending their overpriced toys.
The 40mm F2.8 is better :)

I'm not talking about the abstract "DoF" here. I'm talking about the DoF in the final image. And the final image can be printed whatever size you want. In this test we don't care about what's in that image as long as the image itself represents the same scene. Because if we go to the absolutes, then it is impossible to reproduce a 100% identical image even with the same camera. The test is about the amount of light and after we agree that a 4 times larger sensor creates an image out of 4 times larger amount of light, we can now start to investigate if it was possible to do the same thing with a different DoF, while not affecting the lighting conditions of the scene in any way. And the answer is - NO. The amount of light and the DoF are connected.

The DoF wasn't "invented" intentionally. It's a side effect. Aperture is for light intensity control. DoF cannot be controlled independently, unless you affect the lighting conditions (like ND filters, or flashes, etc.).
Of course, the same lens on all cameras shot from the same distance at the same F-number will create the same DoF. It is only logical. No magic. But then the amount of light in the scene (the source) will be different. The conditions are changed. Everything stay in sync with the Equivalence theory. It just works.
You forgot one thing. The CoC rule. The difference between sharp and blurry. DoF doesn't matter when the picture is small enough. It's not the DoF that makes things sharp, it's the size. If a medium format camera would only have (let's say) 300 huge pixels on the sensor (20 by 15 resolution), then everything would be in focus no matter what aperture you use.

No, you won't get the same picture if you do that.

I feel sorry for you ... your head is full of nonsense and fairy tales :). How do you survive? How old are you? Your parent take care of you?

Go read about the Circle of Confusion if you want to understand DoF. And leave me alone :).

So you have to be confident of your ignorance, otherwise you won't be successful. In other words, you can't be successful until you know what you don't know :). You can't fix it if you don't know what's broken, or you don't agree that it is broken.

Did you break your brain with that thought experiment? :D

@dansclic
What are you talking about?
If the F1.7 lens remains F1.7 lens, then the DoF doesn't change either.

Just shut up you troll :)) I'm not reading your crazy, ignorant, boring BS insults. Give up and get lost. There is nothing you can say to change the laws of logic. Objectively, stupidity stays stupid, for ever. It's not a matter of opinion.

"This formula contradicts "DOF is ... an indication of the amount of light being used to create an image"." - It doesn't.
The indication is not a measurement. If you have 10 different format cameras and you try to shoot the same picture with all the same settings and conditions ... then the DoF becomes an obvious indication of which camera has a bigger sensor and therefore gathers more light. When you see a picture with a very shallow DoF, you don't think it was done with a 1/2.3" sensor, do you? That's what an indication is.

Do you even realize that if your stupid nonsense was true, then you could split the light from one lens into two same exact lenses and then split each of those and so on and the light will just multiply endlessly and here we have a free energy generator and the flying unicorns vomiting rainbows and farting butterflies and a Christmas every day and ... NO, physics don't work that way!

Do a thought experiment and try to experience the cognitive dissonance.
You have a digital camera A and an F2.8 lens on it. You also have cameras B (b for bigger) with an F2.8 lens as well. Camera A has a m4/3 sensor and camera B has four of the same m4/3 sensors glued together in rectangle formation (basically it's a four times larger sensor). Now you are shooting a picture with both cameras, of the same scene, same conditions, same settings, same distance, everything is the same except the focal length which is equivalent (lets say 25mm for camera A and 50mm for camera B) to get the same framing. We don't care about the DoF, forget it. NOW, you are telling me that the sensor in camera A is getting the same amount of light as all four sensors in camera B together. The only conclusion here is that you are an idiot. Congratulations.

You are hopeless. No wonder you are an easy prey for Fuji scams etc. You are wasting your time trying to defend your silly beliefs. They are incompatible with physics. And you don't even try to understand why.
You are done since 10 comments ago.

@Photomino
I don't need help. Thank you.

@cosinaphile
I'm sorry, but we have nothing to discuss. You are wrong, period. Try harder.
I've already answered every possible ignorant question about the equivalence (even your own). You can just browse throw my commenting history and find all the explanations. Of course, you won't do that, because you think you know better (which you don't). So ... good luck.

Those books don't teach you about the exposure in technical terms. They only tell you how to get the right image brightness out of your camera. Where "exposure" parameters are based on old and obsolete rules and tabels. You won't learn physics of photography from those books. Stupefying the ISO sensitivity range to be the same for all cameras was a huge mistake, but it meant to make things easy for any average Joe. The only problem is that now people can't tell the difference between the F-number and the amount of light. Which is amazingly horrible, if you ask me. It is 21st century, but the majority of people are becoming dumber than ever. The Internet is a great learning tool for everything you want, but most people only learn what's easy and not the truth.
Learning is hard. Have a nice life.
