First sensor cleaning

Seven years with the E-Series, first time I had to suck it up and engage the cleaning mode on my latest, the E5. There has been sensor debris before, but it always went away with the first or second SSWF activation, this time for the first time built in cleaning needed an assist. I no longer have a blower brush like the E-5 manual recommends, so I opened the cleaning mode up for the first time ever with Olympus and used my chemical air from about six feet/two metres away. Problem solved. I guess maybe it's something you should expect every 150,000 photos or so. Kudos to Oly, and maybe the E-7 will have a Sony sensor, and maybe Sony will now feature the excellent SSWD.
