Oly 12-40 2.8, reallyl as sharp as primes?

Read a few comments here and there that the Oly 12-40 is as good as primes in sharpness etc.  I am wondering if anyone actually A/B side by side on this?

For example, the 17mm prime is not considered the sharpest.  At equivalent setting, would the 12-40 wide open be as sharp as the 12-49 wide open?  I know that the 17mm is over one stop faster.

How about 12mm wide open vs the 12-40 wide open at 12mm?

Thanks,
