This list is going to be mostly photography related, and from the perspective of fitting everything into a carry-on bag which I would be using on walking photo tours around DC for my first time.

Bag:

The bag I went with was the Think Tank Urban Disguise 60 v2 found here. It fits my MacBook Pro Retina, my entire micro 4/3 kit, and extra batteries to power everything, served as my personal carry-on item at the airlines and also doesn't look like a camera bag and converts to a backpack. Plus all ThinkTank bags come with a rain cover - it rains a lot in DC.

My review on this bag (video review) found here.

Cameras:

Olympus OM-D E-M5 with Olympus HLD-6 Battery Holder
Sony DSC-RX100M II
Autographer
Ricoh Theta

I chose the Olympus E-M5 for its fantastic image quality, super image stabilization, weather proofing, and the fact that I didn't have to buy another body to go. I'll add that I took a long close look at the OMD-EM1, but decided that it was a toss-up in image quality and that I wouldn't benefit much from upgrading.

I also chose the E-M5 over my Canon 6D mostly a weight, and size issue. I knew I'd be walking 10 miles a day, and possibly in some rain. I have to say this was a tough choice not knowing exaclty how I'd feel after walking so much in the heat, but I'm glad I went with the micro 4/3s vs full frame.

The Sony RX-100M II was an easy choice. Its the best overall well rounded compact you can get, that also has a hot-shoe. If you don't need the hot-shoe, go Sony DSC-RX100M III. It has a super viewfinder, and a faster lens - but less zoom range.

Autographer to capture moments automatically.

Ricoh Theta captures everything in a single click, and is the size of half a pack of bubble yums. This is another no brainer for travel and is a fun camera to use for obvious reasons. Being able to capture everything around you in a single click is so refreshing and surprisingly useful. More on that later when I write about my trip.
