The Manfrotto 337 is a compact, double-axis (2D) hot-shoe spirit level that slides into any standard camera hot shoe and simultaneously shows pitch and roll, making it the classic tool for perfectly leveling your camera when shooting panoramas, architecture, landscapes, or any situation where a straight horizon is critical—especially useful on older DSLRs and mirrorless bodies without built-in electronic levels.
The Manfrotto 337 is the original and still indispensable two-way bubble level trusted by panoramic and architectural photographers for decades. Two high-visibility bubble tubes are mounted at 90° to each other inside a tough black plastic housing that simply slides into the camera’s hot shoe. It lets you level the camera both left-right and front-back in one glance—no need for a tripod level or electronic viewfinder overlay. At only 20 g it adds nothing noticeable to your kit and is small enough to leave permanently in your bag.
