After a year away from photography I purchased an Olympus e-m5 and a few lenses (14mm 2.5, 20mm 1.7 and Sigma 60mm 2.8), I noticed that every single lens is soft at the same spot (upper left hand side). The 14mm is the worst of them. I decided to re purchase a lens I knew from my past kit was sharp, the Samyang 7.5mm and even this lens is soft on the upper left. At first I thought I had simply got 3 poor examples of lenses, but after the Samyang arrived today I'm starting to question the camera itself. I've tried everything, tripod shooting with a delay, switching anti shock on/off, switching the stabilisation on/off and it's making no difference. The issue reminds me of a tilt shift on all lenses, one area is completely out of focus and covered in chromatic aberration. When manually focusing and moving the magnification around you can clearly see one half is in focus while the other half is out, eliminating any auto focus issues. I'm guessing this will be a sensor alignment issue? Is there any sort of hard resets on Olympus cameras? Or something that could use the stabilisation to help sit the sensor correctly? Or any ideas at all? I can upload some examples tonight if it helps. Thanks, Chris.
