I love using this camera and the Olympus micro four thirds lenses so much that I have sold both my entire Nikon D7100 kit and Sony RX100 pocket camera. It is the perfect blend of size/weight and all the features an enthusiast would want.

Build Quality And Layout; Evf A Plus Vs Pentaprism; Focus peaking; Light weight and compact; Wysiwyg In Evf

Battery life

The best, most complete all-round compact system camera money can buy

Pro-like manual controls; Rock-steady stabilisation; The fastest autofocus around

Continuous AF can be beaten

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

On the other side of the bodyshell – which comprises magnesium alloy covers and is both fully sealed and insulated – is a dedicated compartment for the memory card which is just so much more convenient than having it share the battery's compartment in the base.

The Olympus OMD E-M1 is the best mirrorless camera on the market, period. Everything about this camera just works and works flawlessly. Image quality is outstanding. With no AA filter, the images are sharp and colors punchy. Viewfinder is the best EVF on the market (as of this writing).

Awesome IQ (image quality) Blazing fast focus/operation Excellent build quality Best EVF/LCD screen Best 5 axis image stabilization Small size (compared to DSLRs) Tilting LCD screen Weather sealed Great handling Customizable dials/buttons Just works

No 24p video

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...

Retro is in. Or at least, most camera-makers seem to be saying so. Though I\'ve never found anything wrong in that approach, it does seem like the legendary OM series from Olympus has taken a step in the wrong direction and seems to have lost itself in the design wilderness.

Fantastic replacement for the E5 and solves all of the issues I didn't like with the E-M5. Better build, weather sealing, built-in grip, better AF with FT lenses and slightly better video.

Hang on, you might be saying; whilst the 16.3 effective megapixel OM-D E-M1 may outwardly resemble a DSLR it's not actually one in the strictest sense, on account of being a mirror-less model.

Solid feel build quality with dust and splash proofed body; in-body image stabilisation; image quality right up there with an actual DSLR to most eyes

Smaller imaging sensor than an APS-C DSLR; button and control layout is busy and can feel a little cramped at times

The E-M1 sits at the top of the Olympus CSC range, and the specs and the price reflect this. It's a solidly-built camera and the retro-inspired design is blended well with the contemporary technology.
