I've been a birder since at least my teens and a bird ringer throughout my adult life until I was bitten by the photography bug. I started photographing birds in 2012 and have not stopped! I started with a Canon EOS 7D and a 400mm f5.6 lens and later a 500mm f4 lens. Since 2020 I have preferred Olympus, initially an EM1X and now an OM1, with 300mm Zuiko lens.
