One would need to save lots of money. I see these photographers, the urban wildlife photographers, carrying their gear around the parks and I'm amazed. They are walking around with around $30,000. (American) worth of camera bodies and lenses, if not $50,000 or more.
It always makes me feel so humble taking my little bird and butterfly pictures with my little digitall camera LOL
Super pics! wow, makes you think of saving for one of those super cams to make such pics. Good to see the birds
