I have received RAWs taken with an Olympus E-M5 and "Leica DG Summilux 25/f1.4" (according to EXIF data).  And, it is heavily distorted.

 

However, http://www.opticallimits.com/olympus--fo...14?start=1 tells otherwise.

 

May it be not the same lens (I must have been adapted at least as far as I can see)?  Was it measured with distortion correction being switched on?

 

(I don't like to share the RAWs in public because they have been sent to me from a third person that I would have to ask first.  However, I would send a link via email if asked for.)

Yes, it is not the same lens.

You simply looked into a wrong review ... this is your lens:

2.73% barrel distortion in the uncorrected image.

 

Just my 2cts ... Rainer
