I do a lot of moving around at events and functions and like to switch between lenses a lot. It's really frustrating returning to my bag and nerve wracking thinking about who might be stumbling on it. So, I've been thinking of getting a vest so I can keep more than just my mounted lens with me. Is that going to be stupid? I mean, I'm a fairly young guy. Is it going to look like a traveled to the future from 1959 and decided to shoot a birthday party? Anyone have any experience using one? Let's say hypothetically I were to get one, what are the draw backs and benefits, things I might not have thought of? Got any good recommendations? Maybe that was too much to ask at once.
