On my expedition to the Ecuadorian Andes, an interesting group of cameras gathered in the thickets of the montane cloud forest: a Canon EOS R5, a Nikon Z9, and a Sony A1. Since it was often the case that all three cameras pointed their lenses at the same Bird at the same time, I started to notice differences in how they dealt with each given task. I found that the cameras in question detected birds’ eyes in different – and, to me, surprising – ways.
