Priced at $24.99 and $59.99, respectively, the OM Magnetic Mount is significantly more affordable, costing about 58% less than the SmallRig cage. While both products aim to enhance smartphone videography, they serve different purposes and offer unique features.
Design and Build Quality
The OM Magnetic Mount features a double-sided magnetic design that allows for stable adsorption, essential for capturing smooth video footage. Weighing only 41 grams, this mount is designed specifically for the DJI OM 8/7P/7 gimbals, making it easy to attach and detach. The SmallRig Universal Phone Cage, on the other hand, is made from rugged aluminum alloy, providing a solid build quality. It weighs 120 grams and offers multiple expansion interfaces for accessories. While both products are designed for stability, the SmallRig cage offers a more robust construction suited for professional videography.
Compatibility
The OM Magnetic Mount is compatible with MagSafe iPhones (12 and later) and includes a universal magnetic ring adapter for Android phones, ensuring versatility for various devices. It is designed to hold both the phone and the OM tracking module simultaneously for seamless operation. In contrast, the SmallRig Universal Phone Cage supports a wide range of smartphones, including iPhone 17/16/15 and various Samsung models, making it universally compatible. This broad compatibility could be crucial for users with different devices, giving the SmallRig an edge in this category.
Features and Functionality
The OM Magnetic Mount offers a retractable back cover extension design that accommodates larger phone sizes and enhances contact area for stability. Its effortless setup allows users to quickly attach or detach the mount, ensuring they never miss a shot. Conversely, the SmallRig cage includes dual handles for increased stability and comfort during shooting, which is essential for dynamic video creators. It also features multiple extension ports for attaching additional accessories like microphones and lights, making it more versatile for professional use.
Portability
When it comes to portability, the OM Magnetic Mount is lighter and more compact, making it easy to carry around. Weighing just 41 grams, it can easily fit into a pocket or small bag. The SmallRig cage, while still relatively lightweight at 120 grams, is bulkier due to its construction and additional handles. For those prioritizing ease of transport, the OM Magnetic Mount is the clear winner, particularly for on-the-go videographers.
Target Audience
The OM Magnetic Mount is ideal for casual videographers and smartphone users who want a quick and efficient way to enhance their filming capabilities without breaking the bank. Its lower price and straightforward functionality cater to hobbyists and those new to videography.
