Hi. Im just noticing that with my Olympus 45mm 1.8 lens, my screen will flicker for a good 5 - 10 seconds when turning on the camera or until I focus on a subject. I cant remember if this happened when I first bought it. Im using an e-pl3 and the screen doesn't flicker at startup with my other lenses (two zoom kit lenses). Should I be worried? Screen only flickers with the 45mm at startup. Once it stops, it doesn't happen again until the next time I turn on the camera.
