The OM-D E-M1 is Olympus’s previous-generation flagship Micro 4/3 camera, the big brother to the Olympus OM-D E-M5, and the predecessor to the OM-D E-M1 Mark II. Key features include:

16.3MP Live MOS Sensor. Designed without a low-pass filter, the high-res sensor produces extremely sharp images. The new TruePic VII Image Processor allows an upgraded ISO range of 100-25,600, has a maximum shutter speed of 1/8,000 sec, and offers up to 10 fps of continuous shooting using tracking autofocus and 6 fps using continuous autofocus. It shoots full HD 1080p at up to 30 fps with stereo sound in either the MOV or AVI format.

Dual Autofocus System. With both on-sensor contrast and phase-detection autofocus, the EM1 provides greatly improved autofocus performance. You have four autofocus options, ranging from 3×3 grouped points for shooting a moving subject down to a single Super Spot point for extreme accuracy.

Five-Axis Image Stabilization. Provides up to five stops of correction on five axes (conventional IS covers two axes) and features a new IS-Auto mode that detects panning.

Two Modes of Image Composition. The large 2,360k-dot electronic viewfinder offers 0.74x magnification for traditional to-the-eye shooting, while the 3.0-inch, 1,037k-dot tilting touchscreen LCD is great for tripod and arm’s-length shooting.

Professional Design Approach. The durable magnesium alloy body features a dust-, splash-, and freezeproof design. The grip is more substantial than the E-M5’s, meaning there’s more space for physical buttons and, consequently, less need for menu diving. The 2×2 control dial—adopted from the E-P5—allows for deeper button customization, while the in-camera intervalometer means you don’t need an additional accessory remote.

Built-In Wi-Fi. The improved Wi-Fi system offers simple connection to smartphones and tablets using the Olympus O.I. Share app. When connected, you can view and download images to the device, and make camera exposure and focus adjustments on the device while shooting. Additionally, your smart device can embed GPS information in the EXIF data.

Other Notable Features. While there are too many other great features to discuss in detail, some standouts include live HDR previews, focus peaking, in-camera lens correction, sensor dust reduction, face and eye detection, a built-in level, a large variety of Auto and Art modes, and a greatly appreciated PC-sync port with 1/320-sec sync speed. The camera records images to SDHC/XC memory cards (not included) and uses the BLN-1 battery, which is rated for around 350 shots per charge.
