I'm pretty much ready to invest in another major piece of equipment within the next month or two. I have an OM-D E-M5. I'm not dissatisfied with it for still pictures, but the USB lack is broken which bothers me more than it should for some reason. I would like to be able to use some kind of remote shutter controller (using USB) for long exposure photography and timelapse videos but it's not my main priority. I am interested in the GH4 because my wife and I are living overseas, and we have a baby on the way. Among other things, I would like to start making videos for friends and family back home. Im interested in the Olympus 40-150 also because I am living overseas and I want to use it to take natural street portraits from a distance. Also, I like to go camping and I feel that it would be a good all around lens for wildlife photography. My current lens lineup is as follows: 1. Panasonic 25mm 1.4 2. Olympus 75mm 1.8 3. Olympus 45mm 1.8 4. Olympus 12-50mm 3.5-6.3 EZ thoughts?
