I purchased this new and used it once with my DJI OSMO Pocket 3. For vlogging, I was able to capture wide shots indoors and for self-portraits. While there's a slight softness in the corners, it's not a problem unless you're overly concerned with 4K high-definition video quality. The magnets are strong, so you can use it without worrying about it falling off. It also fits perfectly in the official case. Includes the filter case, a protective film for the Pocket 3 monitor, the original box, and the instruction manual. [Quoted from Amazon] K&F Concept Magnetic Filter for DJI OSMO Pocket 3, Wide Angle Lens, 120° Wide Angle Shooting Range, 0.72X Magnification, Wide Angle Filter, Magnetic Attachment, Easy to Install, AGC Optical Glass, 28-Layer Nano Coating, Waterproof and Stain-Resistant [Wide Angle Lens] Attaching the wide-angle lens expands the FOV to 112°, allowing you to shoot with a wider angle of view. The magnetic design allows for quick and easy attachment and removal. [Lightweight Material] The filter frame is made of lightweight aluminum alloy, which is durable and does not affect the gimbal of the DJI OSMO Pocket 3. The surface of the filter is treated with black ink to prevent reflections and does not affect image quality. Instant purchase is OK. Thank you.
