Overview of the Products
The OM Magnetic Mount for DJI Osmo Mobile 8/7P/7 Gimbal Stabilizer and the ULANZI U Rig Pro Smartphone Video Rig serve different purposes but are both designed to enhance smartphone videography. The OM Magnetic Mount is priced at $24.99, while the ULANZI U Rig Pro is a more budget-friendly option at $19.95, making it about 17% cheaper. Both products cater to mobile filmmakers but offer unique features that appeal to different user needs.
Design and Build Quality
The OM Magnetic Mount features a double-sided magnetic design that allows for secure attachment to your gimbal and is specifically tailored for the DJI Osmo Mobile series. Its retractable extension design accommodates a variety of phone sizes, enhancing versatility. In contrast, the ULANZI U Rig Pro boasts a robust construction with three cold shoe mounts and a universal 1/4"-20 tripod thread, allowing for extensive accessory attachment. Both designs prioritize ease of use, but the OM Magnetic Mount excels in its quick-release capability, making setup a breeze.
Features and Functionality
The OM Magnetic Mount stands out with its capability to hold both the phone and the OM tracking module simultaneously, optimizing the ActiveTrack feature. It also includes a universal magnetic ring adapter for Android devices, enhancing compatibility. On the other hand, the ULANZI U Rig Pro offers versatile mounting options, including attachments for LED lights and microphones, making it ideal for comprehensive filming setups. While the OM is more focused on magnetic attachment and stabilization, the U Rig Pro provides a broader array of functionalities for serious filmmakers.
Portability and Weight
Weighing only 41 grams, the OM Magnetic Mount is incredibly lightweight, making it easy to carry around for spontaneous filming sessions. Its compact nature allows for effortless transport without adding bulk to your gear. The ULANZI U Rig Pro, while slightly bulkier due to its additional mounting features, is still designed to be portable. The trade-off here is that the U Rig Pro may require more space in your bag, but it compensates with greater versatility in attachment options.
Target Audience
The OM Magnetic Mount is primarily aimed at users of the DJI Osmo Mobile gimbals, particularly those who prioritize quick setups for smooth tracking shots. Its features are tailored for casual users and enthusiasts who want simplicity in design. Meanwhile, the ULANZI U Rig Pro targets a broader audience, including professional videographers and content creators who require multiple mounting options and a more stable filming platform. This makes the U Rig Pro suitable for a wider range of filming scenarios.
Price Comparison
At $24.99, the OM Magnetic Mount is positioned as a premium accessory for DJI gimbal users, while the ULANZI U Rig Pro's price of $19.95 offers a more economical choice for those needing a versatile rig. The approximately $5 price difference may make the U Rig Pro an attractive option for budget-conscious buyers. However, those specifically seeking integration with DJI's tracking features may find the additional cost for the OM Magnetic Mount worth the investment.
Performance in Use
In practical use, the OM Magnetic Mount's design ensures stable adhesion during filming, which is crucial for maintaining shot quality. Users can quickly switch between handheld and mounted modes, enhancing shooting flexibility. Conversely, the ULANZI U Rig Pro's design allows for a variety of filming accessories, which can elevate production quality. Its compatibility with most smartphones further enhances its usability, making it a reliable choice for various shooting conditions.
Which should you buy?
Choosing between the OM Magnetic Mount and the ULANZI U Rig Pro ultimately depends on your specific needs. If you own a DJI Osmo Mobile gimbal and prioritize quick, stable shooting with a magnetic attachment, the OM Magnetic Mount is the clear choice. However, if you are looking for a more versatile rig that can accommodate various accessories and work with a wide range of smartphones, the ULANZI U Rig Pro is the better option. Each product shines in its own right, catering to different aspects of mobile filmmaking.
