Interesting reads. As someone mentioned, just get to know your camera. Know it's limitations and adjust accordingly. As you know, there's a large gamut of lighting and distance situations. I couldn't image trudging around Con with a bag full of lenses. As you mentioned, it's fun just to walk around the floor taking pics of people dressed up. There's also some great photo-ops up in the autograph area... less crowded too.
Anyway, I wanted to take Weds-Fri off at work but we've had a large loss of staff so I can only take Weds off... half-days on Thur/Fri (I'll get off at 10am). Not too bad but I won't be able to camp in the Hall H line on those days...but I'll be camped for Saturday's Hall H.
