i shoot in icebox condition hockey arenas (okay theyre only into the 50s) but marching bands and parades down below freezing in the winter too.
Canon 5D3, 5D4 for my bodies. i started a long long time ago with a Canon EX-Auto (an affiliation with Bell and Howell) before the ubiquitous AE-1 and New F-1n. lots of images with a yashicamat 124G but obviously those werent auto focus
