According to the Olympus press release that the bundled Olympus FL-LM2 Electronic Flash is also weather sealed (dust and splash proof construction). I take this to mean that the accessory port (AP2) itself is weather sealed? Why else would the FL-LM2 be weather sealed right? Is there a more powerful flash either from Olympus or a 3rd party that supports TTL and is weather sealed? Is there one but not compatible with Micro Four Thirds TTL?
