It's debatable. For hi-key, sitcom style full coverage lighting you've got to take the roof off the place and drop in a lighting grid, but with a high-end DSLR and good glass you can light a scene with candles, if that's the look you're going for. A lot of hi-end documentary interviews are shot with only natural light from a window.
When watching YouTube videos and Kickstarter videos where amateurs are trying to pass themselves off as pros, the most common and grievous error has nothing to do with the image, it's the sound that's all fucked up. Unplug the refrigerator and get a proper microphone! Digital cameras have come a long ways in 20 years, but onboard mics are still garbage.
>And tens of thousands of dollars of professional lighting.
There have been great (and even award winning videos) shot on iPhones (or even cheapo dslrs/compacts) with no "professional lighting" or just natural light.
Ask a pro photographer what he would prefer:
1. a cheap entry level DSLR and ultra-expensive light setup
2. the most expensive DSLR and cheap household light setup
Most would pick 1.
