I don’t normally post about firmware updates, but this is a) quite a major one, and b) there are a lot of E-M1 users amongst the reader pool. Amongst other fixes to audio recording, the shutter mechanism is affected. Some cameras – mine included – are affected by a resonant shutter vibration specifically at 1/180s that causes a slight double image; higher and lower speeds are fine. The new firmware adds an option that switches “the first shutter curtain from mechanical to electronic to reduce blur caused by shutter impact”. In our initial testing, it appears to make a significant difference on two of the three cameras we have here (all of the workshop videos are filmed with them, we have a spare, and I shoot one myself).
I first raised this issue to Olympus back in December; it’s highly commendable that they’ve listened, been in regular contact, and given us not only a solution, but a highly innovative one that doesn’t require sending the camera in. Kudos.
The firmware update can be downloaded here. You will need the original (proprietary) USB cable that came with the camera to upload it, though. MT
