All taken with the E-M5 and the M.Zuiko 14-42mm II kit zoom. The E-M5's quick focus, touch screen, and very quiet operation allowed me to get close enough to the animals for the captures. That, and the high ISO performance of the sensor (Ruby at the top and Lucy at the bottom are ISO 3200). The E-M5 is, without a doubt, the best Olympus digital camera I've ever owned, 4:3rds or µ4:3rds. And the consumer zooms I've used, specifically the 14-42mm and 40-150mm, have done excellent yeoman work, especially on the E-M5 body.
This is the digital camera that Olympus has always been capable of producing (see the OM-1), and the digital camera they should have produced before they did. I sincerely hope Olympus produces more cameras like the E-M5, but more importantly, I hope Olympus survives to produce more like the E-M5.
