Completely Agree. can't go wrong with the nifty fifty.
Along with that I also use a Sigma 10-20mm f/4 it's a much wider lens and a deep depth of field. That I wanted for some on the go vlogging so focus wouldn't be too bad. I did an unboxing and review on my channel of it.
They're the two that I mostly switch between. I also have my stock Canon 18-55mm f/3.5 I don't like the quality of this lens but I use it when I need a wide in low light. The Sigma isn't too good in darker situations. I'm looking to replace it with the Sigma 20mm f/1.8. Super wide with large aperture.
I also have the Sigma 70-300mm f/4 amazing macro
But because you're zoomed in so far it shakes way to much for video. unless you have an amazing tripod.
As you could guess I'm a Sigma fanboi. Their a cheaper alternative for lens and are great quality. My favourite part is the rubber rings.
Also think about what you're going to be using them for. A shallow depth of field (50mm) is great for something that doesn't move, like someone sitting in one spot with camera on tripod. Trying to get that while moving will need Constant refocusing. Doable but done wrong will be very noticeable. Moving about and getting a wider image I would my Sigma 10-20mm. I can get up in my face and still get my shoulders. The infinity focus is helpful for moving as well.
It's a big world out there. These are my opinions and recommendations, but at the end of the day it's your style, your camera and your money.
