Here's the thread for the Olympus M.ZUIKO DIGITAL ED 12-40mm 1:2.8 PRO. The following image was taken with the lens in front of an OM-D E-M1 using 1/1600 sec; f/3.5; ISO 200; 17mm (34mm FF equivalent FoV); handheld. Minimal processing in Adobe Camera Raw: no noise reduction or sharpening was used. The full resolution image can be found here
OK, five (or less!) out of ten for artistic merit but I hope this thread encourages others with more talent to post images made with this outstanding lens.
