Hi guys, I have the Olympus PL5 with the Panasonic 20mm 1.7 Gen 1 lens. I was looking at the In-body stabilization setting and noticed the focal length is set to 15mm, but my lens is 20mm. Should I change it to 20mm? And also could this be why my pictures are always blurry when viewed at 100%? Any advice will be greatly appreciated. Thanks!
