Hello everyone, This may be a dumb question but I have an X-T1 and I absolutely love it! I have noticed a big difference with the recent 4.0 firmware but my question is: Do I need to update lens firmware? I was confused when I was reviewing their firmware site. I didn't know if the lens firmware versions were included in the 4.0 update or if I needed to manually install firmware for my given lenses. Does anybody know the answer to that? Cheers! Shawn
