The OM-D E-M1 is the best mirrorless camera ever from Olympus, and it's attracting interest from serious photographers who had, up until now, ignored Olympus and Micro Four Thirds technology. But the E-M1 deserves all the attention—it's the new champ in the "lightweight heavyweight" class.
The E-M1's sturdy magnesium body is splash and dust resistant, and freeze resistant down to 14º F (-10º C). At 1.1 pounds with a battery and SD card, it's lightweight compared to, say, a full-frame Sony A99 (1.8 pounds). And while not tiny, it's not a lot bigger than my iPhone 5 in its Otterbox case.
The E-M1's electronic viewfinder (EVF) is the best I've ever used, with 2.3 million dots providing 100 percent coverage at a stunning 1.4x magnification. At 21mm, the eye-point is high enough to allow me to shoot while wearing glasses. And it doesn't suffer from the high-contrast problem I reported when I reviewed the Sony Alpha SLT-A77.
The E-M1's body is packed with buttons and levers and switches, yet everything makes sense and the design is not busy. Atop the power switch on the left you'll find two buttons that, by default, control focus options and HDR or bracketing. On the right side of the camera are front and rear dials for aperture and shutter that, to me, are placed exactly right, along with the mode dial (now with a locking button), and two function buttons. The default uses of the buttons make sense and you can certainly start shooting immediately, but practically everything can be reconfigured to suit your preferences. The Fn1 button, which I've set up for ISO, sits directly under my thumb. I can find every button on the outside of the E-M1 without hesitation and without having to take my eye from the EVF.
One do-hickey on the back of the E-M1 deserves special mention: the two-position lever. By default, it changes the functions of the front and rear control dials. But it's highly configurable, like almost everything else on the camera. I have repurposed it to toggle between autofocus and manual focus.
The E-M1 comes with a small detachable flash. I use it only for optical triggering of several Olympus FL-600R flashes. The E-M1 lets me control groups of remote flashes from the back of the camera.
And how fast is the E-M1? Max shutter speed 1/8000th of a second. Max sync speed for flash: 1/320th second. Max continuous shooting speed: 10 fps. It's fast.
Do your job right as photographer, and the E-M1 will deliver images that do not disappoint. Automatic exposure is on target, if a bit conservative. Color is accurate and well saturated. I recommend shooting raw for maximum flexibility, and the E-M1's ORF raw files give you lots to work with. But thanks to the TruePic VII image processor, in-camera JPEGs are quite good, with automatic correction of lens distortion and chromatic aberration. I continue to use DxO Optics Pro 9 to make these adjustments to raw files on my computer, but I'm starting to wonder if I'm not doing things the hard way.
