 there is very little difference between a 4 stop underexposure at say ISO100 ...

 

Once upon a time people used to preach ETTR (Expose To The Right).

 

I always argued with them that the best exposure for a shot was the correct exposure. But no, there was this school of thought that you had to push the histrogram as far to the right as possible. Maybe they were a bunch of rednecks. Who know?

 

Finally, people have got it that with just about any camera these days as long as the highlights are more or less protected your image will be fine.

 

Getting 4 stops underexposure? That can only happen with people who insist on shooting 100% in M mode.

 

But that's getting into shooting A vs M, and let's not go there. 

 

As a side note, I just dropped 130€ to get the internal flash fixed on my D800.

 

Another good reason to get the D850. My total cost could have been under $3000 (3300-130 - 160km trip x2).
