Many times, when we see a large building, or a landscape that just screams ultra-wide view, because there is so much to take in. We want to take multiple photos to show the breath taking view, or the large size.
Well, the Olympus OMD E-M5 has a scene mode that has the needed panoramic guides so you stitch them together later. Any Panorama Software will work. I use Microsoft ICE, a free Panoramic Software. The Software that is supplied with the Olympus OMD E-M5 can also stitch them together. You will have Fish-Eye effect if your panning is pretty wide. Using a wide-angle lens like the 14mm or 12mm will allow you to take less photos for your final panorama.
Here is a finished 4 image panorama.
You can take up to 10 images, in vertical or horizontal panning
Here are the simple instructions from the E-M5 PDF Manual page 60
