I own the XT3 and several other Fuji lens. (kit lens, 16mm 1.4, 10 to 24mm, 23 f2, 55-200mm) I just recently purchased the 56mm 1.2, so when I'm focusing on my intended subject and depress the shutter half way, sometimes the subject appears zoomed-in in the view finder. I'm talking magnified 3 or 4 times what it should be. Then I release the shutter, re-focus and it's normal again. It doesn't happen all the time, but at least once or twice whenever I shoot. Any Ideas?
