This will be much better than your cameras onboard preamp. I've used it on a Pansonic G9, Canon 80D, and Fuji X-T30. However, you just have to know what to expect from these types of mics. Having your subjects 10-15 feet away will be optimal, anything beyond that and the volume during playback won't be as loud, obviously as a result of their distance. The most significant difference between this and your built-in camera audio is the control over the ambient hissing sound. This is a cardioid condenser mic that is good at filtering out background noise and isolating the voice of the speaker for recording. It's a great directional mic which means it's does best at pickup up audio when your subject is in front of you. Overall I have not complaints. Check out audio tests between this and the Movo and the Boya. All reviews talk about how similar they are with the latter 2 being 10-20 dollars cheaper. There is very minimal difference but people usually prefer the cheaper ones because of how close they are in sound at a lower price point. Because this does have a slight, very slight advantage I will keep this one and pick up a Boya as a backup or spare.
