I have a range of different cameras, from film to aps-c to full frame to Micro Four Thirds, but which is the camera I grab when I'm travelling, or going for a camera walk in town, or going on a motorcycle trip? Well it's my trusty and very compact Olympus OM-D E-M5mk2 and the wonderful 17mm f1.8 lens. They are truly tiny and easy to slip in anywhere or ride with while dangling from a strap. I also have the very excellent Olympus 12-40mm f2.8 PRO lens that has image quality in spades and is very versatile, but it is bigger and heavier than the 17mm by a long shot and the E-M5 always feels somewhat unbalanced with it attached. Add the very tiny Olympus 45mm f1.8 in a spare pocket to pair with the 17mm and you are covered for a good range of shots anyway. I truly hope that the MFT system stays around for a very long time, what a pleasure to carry it about!
Here is a quick comparison pic of a full frame and an MFT body side by side, add similar focal point lenses to them and the size difference grows exponentially. I know which one I would rather lug about on a trip.
Here are a couple of pics taken while travelling by motorcycle through some Swedish forest a while back:
