Regarding what #2 said about which version you bought... you really gotta double check that model number on the bottom or the ring. If it doesnt say Mark III on the front, there is 100% no mic jack, period. I remember being so frustrated when I first got mine for a vlog series; I actually tried to buy a USB-to-3.5mm adapter thinking I was clever, but the camera software just wont recognize it. Total waste of money, so be careful not to fall for those universal adapter scams you see online. They do not work with this specific Canon firmware. Since you are on a tight budget for your Kyoto trip, I might want to consider using your smartphone as the dedicated audio house. I have done this for years when my main rig failed. I suggest picking up a Purple Panda Lavalier Lapel Microphone Kit. It is super budget-friendly and comes with all the bits you need. Just plug it into your phone, hit record on a voice memo app, and tuck the phone in your pocket. One big warning tho: make sure to do a loud, clear clap on camera at the start of every take. If you dont have that visual and audio peak to line up later in your editing software, trying to sync your voice to your lips is gonna be a total nightmare. TL;DR: Older G7X models have no mic jack. Use a lavalier mic with your phone and sync the audio files later using a clap for timing.

Ugh, I totally feel your pain. My first G7X caused me the same headache years ago. Hate to be the bearer of bad news, but if you have the original PowerShot G7X or even the Mark II, there is physically no 3.5mm jack on the camera body. Canon didnt add that port until the Mark III came out, which was basically a huge mistake on their part tbh. Since you are going to Kyoto (so jealous!), dont give up on the camera yet. The image quality is still top-tier for a point-and-shoot. Personally, I have been super happy with a simple workaround that fits your $70 budget perfectly. Since you cant plug a mic directly into the body, you just have to record your audio separately. Heres what has worked well for me:

• Get some stick-on wind muffs like the Movo WS-G7X Micro-Fiber Windscreen. You just peel and stick them over the tiny internal mic holes on top. It helps a ton with that Kyoto wind noise.
• Pick up a portable recorder like the Sony ICD-PX470 Digital Voice Recorder with USB. You hit record on that, keep it in your pocket or clip it to your shirt, and then sync the audio files later in your editing software. This setup has served me for years and I am honestly satisfied with the results. Its a bit more work to sync files later on, but the audio quality from a dedicated recorder is miles better than any internal camera mic anyway. No complaints once you see how clear it sounds!

@Reply #3 - good point! I was in the same boat and honestly felt so defeated lol. If you have one of the older models without the jack, you just gotta pivot. I have been really satisfied with using a separate recorder and some simple stickers to fix the wind issue without breaking the bank. Since you are on a budget, these worked for me:

• GGS Larmor Windscreen for Canon PowerShot G7X - these are fur stickers that go right over the built-in mics. It sounds simple but they are total lifesavers for wind.
• Sony ICD-PX470 Digital Voice Recorder - this usually runs under $60. Just record to this separately and sync it in your editing software. It is an extra step but the sound is way more reliable than the internal mic anyway. No complaints once I got the hang of it! Kyoto is gonna be amazing... that city is so beautiful.

^ This. Also, which version did you buy? I felt so relieved when I found the Movo VXR10 Cardioid Condenser Microphone for my setup, it works well and saved me serious cash.
