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

JPEG files somewhat over-processed

The second of the bigger mirror-less cameras from Olympus, the E-M1 reinvents the an SLR from the 70s with bits of today, making it a standout camera for tomorrow.

Great design and weight; Two megapixel viewfinder is very clear; Supports WiFi and wireless shooting with smartphone app; Smartphone camera application can show images building in real time; Lock button for keeping shooting mode selected; Lots of buttons; Comes with small external flash

While we like the amount of buttons; this number may confuse people; Screen only pops out at various angles; as per normal with other Olympus cameras; No built-in flash; Colour filtration modes only officially apply to JPEG; and while can be used with movies; can't be shut off in these modes

The OM-D E-M1 represents the best that Olympus has to offer in the compact system camera (CSC) market. It's a Micro Four Thirds-based, interchangeable lens camera that balances the needs of pros and enthusiast photographers in one neat, and solid package.

Strong build quality; Excellent controls; Excellent image quality; Fast performance

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

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 OM-D E-M1 takes over as the flagship camera for Olympus. It's a Micro Four Thirds-based camera with a stack of features that's aimed at those of...

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.

Lack of time and sleep during the past 6 months due to my hectic schedule have resulted in severe delays of publishing reviews on this website. On one hand, I wish I wrote this review much earlier when I first got the Olympus OM-D E-M1.

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.

Image quality no better than EM5 or GX7; Continuous AF isn't as confident as a DSLR using v/f; Phase Detect AF not used for movies or MFT lenses; Movies only available at 30fps; Focus peaking only for stills; not movies; Timelapse & miniature movies encoded at low frame rate; Only one memory card...

At the Photokina trade show in September 2016, Olympus was one of several brands to announce it was developing a new flagship camera. Now the finished product has arrived, in the shape of the Olympus OM-D E-M1 Mark II.

+ Extraordinary in-body image stabilisation system allows handholding at unprecedented shutter speeds; + Class-leading continuous shooting performance; + Impressive continuous autofocus and tracking; + Superb build quality and handling

Menus and configuration hugely over-complicated; Image quality lags behind APS-C peers; High price compared to its closest rivals

The Olympus OM-D E-M1 Mark II is befitting of the term 'flagship,' and performs every bit as quickly as such a title implies - and it should, given the $2000 MSRP (body-only). At first glance, it looks remarkably similar to an E-M1, but there's been some meaningful tweaking of body elements, from a...
