It's all about being small and portable
The portability of the micro four thirds system is amazing. Pictured is a M43 Camera (GM5) with a 12-32mm lens (24-64mm equivalent) a 35-100mm lens (70-200mm equivalent) and the new SLR Magic 8mm lens (16mm equivalent).
This kit is not for everyone, but for folks who climb, hike long distances, trail run, bike ride, are obsessed with weight and pack light there is nothing that beats this system for creating professional images in a camera with a three lens set up that can easily be held all at once in your hands.
Now let’s look at how the tiny SLR 8mm lens compares to my favorite wide angle zoom, the Panasonic 7-14mm f4 lens
