Samsung's latest travel zoom packs an absolutely massive 21x optical zoom into a pocket-ready frame. It's the longest zoom ratio we've seen on any compact camera; that distinction changes a few times a year, but we'll let the WB850F enjoy its moment in the spotlight. But that's not the only trick up this camera's (extended) sleeve. It's equipped with Samsung's new SMART WiFi system, opening it up for on-the-go photo sharing, cloud saves, automatic PC backups, and a bunch of other "connected" features. We spent a few minutes with the WB850F at CES 2012. Read on for our first impressions of the world's longest-zooming compact.
