Some people say it’s not such a big deal not having a headphone jack in cameras like the Panasonic GX80, G85 or even the upcoming Canon 6D Mark II. They say they just adjust the levels and they’ve never encountered a problem. But this is a bit like recording video by just checking the histogram. Just because you’ve been lucky and have never experienced an SD card malfunction doesn’t mean it won’t happen. I don’t wear headphones while vlogging, but if I’d been able to monitor the audio after the take, I could have at least recorded it again.
