Distortion is measured with corrections? - bronger - 10-12-2013
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--four-thirds-lens-tests/509-leica25f14?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.)

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

2.73% barrel distortion in the uncorrected image.
Just my 2cts ... Rainer
