Radius Mini-ALTO Add-On Reviews

Super Convenient

I've used this blimp on a couple of jobs, and I'm happy with it! The magnetic clasps are STRONG, so there are no concerns about leaks. It's really so convenient to be able to pop it on/off at a moment's notice. As a location mixer, it makes all the difference that it's smaller than other blimps on the market, too. The only thing to keep in mind is how you suspend the microphone within the blimp, because I've had the capsule bump against the sides during super-intense moves. It's give-and-takes with the smaller diameter. Overall, super convenient and does pretty well in windy conditions, especially with the fur.
