GoPros and other small cameras have become commonplace for allowing the capture of different perspectives. They’re rugged enough to brave the elements but have a fixed lens that make many shots look similar.
The E1 trades the GoPro’s ruggedness for some of the flexibility and quality of DSLR cameras. Instead of the fixed lens used by GoPro, it can take advantage of the lenses used by “micro four thirds” (MFT) cameras such as those from Olympus and Panasonic. Instead of using the the same fisheye effect to capture everything, MFT lenses can handle long telephoto zooms and wide-angle shots. The MFT system comes close to the quality of full-fledged DSLRs, but the lenses are quite a bit smaller. Even so, the combination can get a bit unwieldy for long zoom lenses.
