I use two cameras on a regular basis: my iPhone 7 Plus and an Olympus OM-D E-M1 Mark I. The latter has been my workhorse since 2014, when many Engadget staffers started using it for field assignments. I've taken it to almost every press event I've attended these past two years, and the results are rarely disappointing. Still, the idea of a faster model with a better autofocus was tempting. That's where the recently launched OM-D E-M1 Mark II comes in.
