Pretty much everyone starts out with the Nifty 50, and Canon really needs to bring one to the EOS RF system.
If you’ve been shooting photos seriously for a lengthy period of time, you’ll remember some of the first lenses you used. If you’re like me, one of your first serious lenses was a Nifty 50. If you’re a former or current Canon user, then you probably started with their Nifty 50–the fantastic 50mm f1.8. (It is fantastic relative to the price and performance for its price point.) Currently, the mirrorless camera world has nothing that high-quality that is affordable to the point of near disposability. But think about all the images you created with that lens, and how it made you fall in love with photography. Yongnuo has tried to create lenses like this, but it’s rational to ask for something a bit higher grade at a cheaper price point. In all seriousness, this is what is missing right now in the mirrorless camera world.
