The iPhone's slick design makes it difficult to attach many accessories. The OWELO Bubo fixes that minor nuisance. A solid aluminum stabilizer and mount, the Bubo gives users two grips to hold onto for steady video shooting. It also comes with a 37mm wide-angle lens and a small microphone that connects to the phone's headphone jack. If you need more than that, you can throw on more powerful lenses or attach a light source into the hot shoe. The four tripod mounts—two on the top and two on the bottom—round out the connection set. All-in-all this is a must-have for those serious about shooting video on their phones.
