The Olympus E-M5 is the first camera that Olympus has released as part of their OM-D line. This mirrorless Micro Four Thirds camera also features an electronic viewfinder in addition to its mirrorless configuration.
Olympus’ powerful 5-axis picture stabilization technology is incorporated into this product as well. In continuous shooting mode, the E-M5 is capable of capturing up to 9 frames per second. We evaluate a variety of memory cards by measuring their write speeds and seeing how this affects the overall performance of the camera.
Test Your Writing Velocity
At the beginning of every test, the card is formatted in the E-M5. The camera is set up on a tripod and pointed in the direction of a very specific test scene. The camera is currently set to continuous shutter release mode, manual focus, and manual mode, with the RAW image mode, selected.
For the purpose of determining the right time, five bursts of 15 frames each are created and timed using the card access symbol. When calculating the write speed, the total number of bytes written is divided by the amount of time spent writing, measured in seconds (1 megabyte = 1,048,576 bytes).
