Ok, so I've read a few things about this, but still can't quite see the big gains of FF. Hence I've come here to ask 
So, basic stuff:
Bigger sensor = better ISO, less noise
Something about DoF being better, didn't know the reason, but fair enough.
That said, these reasons don't seem articulately spectacular. You're paying a premium for FF, and if you spent more on any camera you'd expect the above to improve, is this simply a tech advancement achieve these upgrades?
Ok, so next thing seems to be said is that you get more out of your lens, but I don't really get that either....
What about full frame makes an L lens (hypothetically) better on FF than on crop?
The other thing is obviously focal length. But this just seems a bit of maths. Especially with the sigma 35/50/85 range.
If I want a 50mm on a 1.6 crop, just get a 35mm, if I want an 85, get a 50.
The obvious limitation is at the wider end the scaling up might be an issue. But on the other hand, any tele lens nicely gets longer.
So I'm sure I'm missing something, but yeah, who feels like explaining?
