Eyepatchentertainmen teaches you how to choose the best prime lens for Canon cameras, for video shooting. The faster the lens, the lower the light we need. The dark sequence was shot using a Nikon 15 mm 1.8 lens. Canon 50 mm 1.8 or the Nikon 50 mm 1.8 are good starting prime lenses. These run about 100 dollars. Sigma 30 mm 1.4 is a way up from that. After that there is the Canon L series primes, those are very good as well. Adaptation is also needed when you start using lenses. The most expensive is not the best for your usage. EBay lens buying experimentation is also needed, for low-cost projects.
