Men’s Journal editors went hiking and kayaking to test some of the best new 4k cameras that you can use to capture video and photos on land, water and in the air. We hiked up Bear Mountain, just outside of Poughkeepsie NY and kayaked around the Sleepy Hollow Lighthouse with Hudson River Recreations to see how our cameras would hold up under real-world adventure conditions. We tested the DJI Osmo Action, Sony A6400, Canon EOS R, Blackmagic Pocket Cinema Camera 4k, Sigma Art & Cine lenses and the DJI Mavic 2 Zoom.
