I hired a Canon 300mm f4 lens with a 1.4 converter, which tuns it into 420mm, for the weekend and went to Auckland Zoo to try it out. The next morning I got up at 3am and caught a ferry to Tiritiri Matangi island. This is a bird sanctuary where a once bare lump of rock has been reforested and native birds reintroduced. I went to hear the dawn chorus so I could experience what most people in New Zealand have never heard — what their country sounded like before man arrived. Incredible, an avian orchestra the like of which I have never heard. As for the long lens: bloody hell, I wish I owned some kit like this!
