OM-D E-M5 Test 2012 (filtered by lens) — photo 1 of 2: The standard flash for the Olympus OM-D E-M5 camera is not built-in, but attaches to the hot shoe — which is fine with me, because I don't use flash very often. In order to give you an appreciation of its small size — as well as the cute little storage pouch that comes with it — I have taken a picture of them next to a golf ball. For this shot I used a Panasonic Lumix Leica 45mm f/2.8 macro lens (90mm equivalent), at 0.4 second, f/7.1, ISO 200, with a 1.7 exposure compensation. I had to place the flash unit upside down, because it won't stand up by itself when right-side up. July 2012. Camera used: Olympus OM-D E-M5 with Panasonic Leica 45mm f/2.8 macro prime lens.
