It's really basic physics...
Excellent analysis and explanation.
I had already decided on FF due to your previous posts in this thread but now I'm even more convinced FF is the upgrade I need to do. I think I will be getting Canon 6D
the 6d is a low-rez sensor with a really weak d.r. vs. iso curve... a good crop sensor camera like the a6300 will give you more resolution and roughly equivalent d.r. vs. iso:

Key word "roughly". He can feel free to run it through DXO , studio samples, etc. Is it the best sensor? No. Absolutely not. Is it VERY good for its price? Arguably yes
there are many options that are better than the 6d.
i posted the a6300 as only one example of that; it's a crop sensor that's better than the ff 6d sensor.
the a6300 is over $200 cheaper than a 6d here in the states; the lenses are smaller,
Just curious how many "equivelant" lenses are there? You were busting Jaque's chops in another thread. Same rule applies here.
everything that i said went right over your head.
the d750 is only what, $140 more than a 6d? they are both ff; your little lens rant about equivalence was irrelevant to the overall point that i made.
to give you an idea of how bad the canon 6d is... look at the old ff nikon d600, circa 2012; it has a couple of stops of better d.r. than the 6d:

not sure why you are defending canon like that, but it's very misleading for the o.p., and other people who are reading this thread.
canon has strengths in other areas, including a huge lens selection.
My problem is your choice of adjectives. It is fine to point out something is "better" or preferred. It is another thing to insult people and call equipment "junk" just because you prefer something else
Jeez........
don't claim that i "prefer" any dslr, you should know by now that i hate dslrs

this thread is about giving the o.p. the correct info about what *he* wants.
