Since I don't own any 4/3 lenses, I opted for the free FL300R flash when I got my E-M1. This morning I decided to play around with the E-M1 RC mode, and the WIFI feature, so I broke out the flash and iPad and started annoying my son, bed head and all. ISO 200 1/60 F2.8 40mm Flash mode set to "Normal" (Wide and Normal are your only 2 options, set by a switch on the side of the flash), and "Fill". It's bouncing off the ceiling. The focus point was set and the camera was fired remotely using the iPad. Color is set to "Natural" and White balance is set to "Auto". Bounced lighting: Direct flash: The TLL RC system was capable of balancing the lighting pretty nicely. The only light in this room is coming from 2 laptop displays, and it's very dark. If I had shot this without the flash and metered for my son's face, the windows behind him would have been completely blown out. If I had metered for the background, he would have been a silhouette. The camera / flash did a great job of automatically balancing the background and the subject in both situations (bouncing and direct flash). The Olympus Photo Sharing tool on the iPad to me is a mixed bag. I love that I can use Live Time / Live Bulb via WIFI, or even change the camera mode from WIFI. All of the basic settings are there. Even if the mode dial is set to say, Aperture Priority, you can switch to Manual via WIFI and activate Live Time from the iPad software. You can then view the image as it develops on the iPad and stop it when you're ready. This is pretty amazing for long exposures. On the other hand, it you set up WIFI on the E-M1, you appear to have to give up control of the camera until you turn it off again. On the Canon 6D, I can hand the iPad to my wife and she can see the shots as I continue shooting. I can't overstate how nice this is in a studio setting. Enabling WIFI doesn't prevent me from using the camera on the 6D. On the E-M1, this seems like a huge oversight, but not something that can't be remedied via a firmware update. I hope to see this changed in the near future.
