I did a solo mountain-bike ride in Estonian back-country. Only camera I had was a5100 with kit lens. I carried it in my bike jersey back pocket all time. So, it's quite pocketable. It was two day trip, 100 km each and I made some stops to shoot beautiful landscape. 50 shades of green... Here are some photos from this trip.
