Interchangeable-Lens Cameras: Panasonic Lumix GM1

Best for Travel

The GM1 packs a large sensor array into a miniature retro-styled body. (It's less than four inches long and weighs less than half a pound.) Unlike other micro mirrorless cams, this model includes a 12mm–32mm pancake lens that doesn't sacrifice performance for pocketability. [$750; shop.panasonic.com]
