The Olympus OM-D E-M1 is a fantastic mirrorless camera that is designed for the advanced or professional shooter. Those without sophisticated photography knowledge will get easily lost in the numerous features and functionality.

Great image quality; Weather proofed; Awesome grip; Great autofocus; Great viewfinder and LCD screen; DSLR-like feature set

Noise can be an issue at high ISOs; Cost; No second memory card slot

I've said it before and I'll say it again: the Olympus OMD EM1 is a triumph, a highly satisfying camera that I can highly recommend to anyone who wants semi-pro performance and handling without the heft of a traditional DSLR.

Excellent image quality with very usable OOC JPEGs; Weather-proof body; Built-in stabilisation works with any lens you attach; Superb ergonomics; controls & customization; Large & detailed electronic viewfinder.

Shutter button too squishy for our liking; Some noticeable LCD and EVF flickering under fluro lights

Back in 2012, when we reviewed the Olympus OM-D E-M5 we called it the "best Olympus compact system camera to date, and also a strong contender for best compact system camera full stop.

The Olympus OM-D E-M5 was one of the most popular cameras of last year, owing to the combination of an impressive specification, attractive retro looks and excellent image quality. The E-M1 looks to pick up where the E-M5 left off.

Superb electronic viewfinder; Responsive AF system; Good image quality; Sturdy build

This review supplements the detailed 'First Look' at the OM-D E-M1 , which we published in September and focuses upon the new camera's performance in our standard suite of tests with the new M.Zuiko Digital ED 12-40mm f/2.8 Pro lens , which is reviewed separately.

The 16 megapixel E-M1 is the company's top micro four thirds camera. It has a 2.36 megapixel electronic viewfinder, dual contrast and phase detection auto focus, five axis sensor-shift stabilisation and built-in Wi-Fi with remote control from a smartphone. The LCD swivels on the vertical plane.

, this means this camera should be, and thankfully is capable of the highest quality photos of any Micro Four Thirds camera, and when used with high quality prime lenses, the difference can be seen, although is quite subtle at times, with the previous model, the Olympus OM-D E-M5 already providing...
