Olympus' OM-D E-M1 has been one of our favorite mirrorless cameras since its introduction in 2013. It impressed us with its build quality, image quality, ridiculous amount of manual control (that's a compliment) and boatload of features. Three years later, it's still very competitive.

To say that Olympus has outdone itself with the E-M1 Mark II is an understatement. The company told us that this camera was overdeveloped, and it shows. Its blazing dual quad-core processors allow for 60 fps burst shooting (18 fps w/continuous autofocus) and ridiculously fast image playback. Combine that with one of the most advanced autofocus systems we've seen and 5-axis in-body image stabilization – along with what made the original so impressive – and the Mark II is a force to be reckoned with.

One thing about the Mark II that makes us pause is its price. While its MSRP of $2000 is equal to that of Nikon's D500 and full-frame D750 (though, at time of publication, they are selling for $1800), the Mark II's Four Thirds sensor is small in comparison to the D500 and other APS-C cameras and tiny versus full-framers.

At the time of its launch Olympus also debuted a number of accessories to go along with the E-M1 Mark II. The one most people will likely purchase is the HLD-9 battery grip ($249), which doubles battery life and offers two control dials and two custom buttons. It also features a DC-in jack, so you can power the camera via an outrageously priced AC adapter.

Also available is the powerful FL-900R external flash ($299), which has a guide number of 58m, built-in video lamp, wireless control and the ability to fire at 10 fps. The STF-8 Macro Flash Set ($479) has fully adjustable (and removable) left and right flashes, manual control down to 1/128 power and support for focus stacking. Both of these flashes are weather-sealed.

For those who want to take the camera underwater there's the PT-EP14 housing ($1299). It works down to 65m/196ft and numerous brackets, weights and arms are available. Naturally, you'll need a housing for whatever lens you attach.
