For shooting at zoos, I use a 70-300 mm telephoto on my DSLR with an APS-C sensor. For the smaller birds and reptiles, I pack a 105 mm macro lens. Keep it simple. It’s hard to change lenses when all your gear is hanging around your neck. My choice of a camera bag for this kind of photography is a sling-type bag with one strap that lets you swing a backpack around in front of you. I’ve used a LowePro Sling for several years. This sling bag hangs on your back, out of the way when you’re on the trail, but offers quick access to your camera when you’re ready to shoot. Unlike a shoulder bag, a sling bag is more secure when you’re working in a crowd.
Take a short drive to your local zoo and get some fresh air. It’s time to travel.
