From Wildlife and sport: My picks: - Starting out: an APS-C mirrorless body with a 100-400mm-class zoom. The best value reach there is. - Hiking and travel wildlife: Micro Four Thirds with a 100-400mm. Light, long and stabilised. - Serious sport and birds: a full-frame body with fast readout and a 200-600mm or 150-600mm zoom. Buy used: long lenses hold their value and change hands a lot, and the savings are large. See buying used.
