In Diablo 2, magic find had a fairly well known formula, with no diminishing returns for magic items, and then different curves for rare, set, and unique items (with unique-find diminishing the fastest).

After deciding on the base item type to drop, D2 would roll a chance for it to drop as unique based on the monster, your magic find, and the diminishing return formula, if that failed, it would roll again to see if it dropped as a set item, then again for rare, and finally for magic, dropping a non-magical item only if all of those checks failed.

Does Diablo 3 drop items and use diminishing returns in the same way? If so, is the formula the same, or was it tweaked?

I have personally seen the stats showing diminishing returns.. at about 40% each point you put on shows up less points when you look at your stats. at 50% I put on a 7% item and only got 2% I hope this helps..

Tested in solo(Private game): Current set I was wearing had 21% magic find.

Added a 10% belt.

31%MF

Switched pants from 0% to 12%

43%MF

Switched a 21% hat to a 25% hat.

47%MF

The percentage shown in details does not reflect this theory.

I have a barb in Act 2 inferno and I have been following the game since 2008...

BASHIOK Q/A:

"QUESTION ASKER: Is Magic Find using diminishing returns in the same way as in Diablo II, where Magic Find stat affected in a different way the chance for blue, yellow and gold drops (actual bonus of MF was diminished for rarest items)? BASHIOK: No, it’s a literal (and lateral) improvement across the board. We may tweak it but that’s the way it is right now."

It doesn't include diminishing returns at the moment according to Bash. This was pretty much confirmed in a tweet Bashiok posted a couple of days ago.
