Default Incident light

Why don't digital cameras give the option of measuring incident light?

Because they measure light through the lens. Put a diffuser over your lens, and the camera will measure incident light.

That's what i mean. It should be easy to get a dslr to get incident light mettering. As far as i know is foolproof. Where's that diffuser?

You could probably use an ExpoDisc:

Aha... But then I better use my Sekonic L-508 lightmeter. I was dreaming about an IN CAMERA incident mettering. Why not? 90% of my best film picks were incident mettered. It's almost totally reliable.

I've read of instances when people have made flash diffusers from empty milk containers. You could try that, and I bet it would be cheaper than an ExpoDisc.

I want this: i press a button and get infallible incident light mettering.
No grey cards, no white cards, no spot or ultra zoned sofisticated mettering.
You may say I'm a dreamer...

Cameras meter what they see. What they see is what the lens shows them. A fisheye lens will give the camera a view that will allow the metering system to select an exposure based on what is essentially incident light. But if you change the lens, then the metering system will only meter on that portion of scene, which may or may not coorespond to the exposure settings selected when using the fisheye lens.

In other words, get over it.
