The exhibit hall opened on Tuesday night at NANPA, where Canon, Nikon, Lowepro, and many others displayed their wares. I was working in the Lowepro booth, talking with photographers, taking pictures, and answering questions. As you might suspect in a room of nature photographers, the most popular bag was the Lowepro Pro Trekker 600 AW. As one shooter said, "I need a bag that can hold my camera gear and my personal items when I'm working in the field.
Here's a short video of the Lowepro booth and a photographer giving the Pro Trekker the once over.
