so i finally pulled the trigger on a lumix s5ii for my travel vlogs but the onboard audio is just... yeah not great lol. i'm heading to vietnam in like three weeks and need a solid mic. i've been looking at the rode videomic pro+ since it's everywhere but i also keep seeing the sennheiser mke 400 pop up as a better compact choice. i'm kinda confused though because some forum posts say panasonic cameras have noisy preamps and you need a mic with a +20db boost to keep the noise floor down but others say the internal processing handles it fine now? my budget is around 200-250 bucks. honestly just want something that wont clip or hiss like crazy when im in busy markets. which external mic is actually the best fit for these panasonic bodies?
Unfortunately, after years of shooting with Lumix bodies, i have found that the audio preamps remain a weak point that requires a very specific setup to overcome. Even with the newer S5II, you really have to push the mic gain and keep the camera gain at a minimum to avoid that persistent floor hiss. It is a bit of a letdown that we still have to deal with this in 2024.
^ This. Also, my experience in Hanoi:
TL;DR: Use a high-gain mic like the Shure VP83 LensHopper Condenser Microphone and keep your camera gain at the lowest setting to kill the hiss. Building on the earlier suggestion about the +20dB boost, I have been incredibly satisfied with the Shure VP83 LensHopper Condenser Microphone for my Lumix setups. While many people default to Rode, I find the Shure has a much more natural sound profile that doesnt clip as easily in loud environments like a busy market. The technical reason you want this specific setup is all about gain staging. If you let the S5II handle the amplification, its internal preamps introduce that floor hiss we all hate. By using the +20dB toggle on the Shure, you are providing a hot signal that allows the camera to stay at its cleanest, lowest gain level. I have compared it directly to the Rode VideoMic series and the Shure feels much more robust for travel. The integrated Rycote Lyre shock mount is basically indestructible compared to some of the flimsy plastic mounts out there. It also runs on a single AA battery which is super convenient when you are in the middle of Vietnam and cant find a specialized charging cable. It has worked well for me for years without any complaints.
Regarding what #5 said about "TL;DR: Use a high-gain mic like the Shure..." - its amazing how much we still have to worry about gain staging even with modern mirrorless tech! Basically everyone here is saying the same thing: keep the camera gain low and let the external hardware do the heavy lifting to avoid that floor hiss. Coming back to this, it reminds me of a wild DIY project my buddy tried with his Panasonic Lumix S5II last summer! He was obsessed with getting clean audio for a documentary and decided to build his own parabolic dish out of an old umbrella and some acoustic foam he found in a dumpster. He spent hours calculating the focal point and soldering a custom preamp circuit from a kit he bought online because he wanted to hit a specific signal-to-noise ratio. I love it when people go full nerd on specs! We took it out to a nature preserve and every time a breeze caught the umbrella, it made this high-pitched whistling sound that completely drowned out everything else! We spent the whole day troubleshooting the impedance levels on his home-made board while the actual birds we were supposed to record just flew away. It was a total disaster but honestly so much fun to see the technical side of it fail so spectacularly!
My buddy told me the exact same thing last week. Guess he was right lol.
Came here to say the same thing lol. Great minds think alike I guess.
