This video made me rethink my views....
I agree with him and a lot of what TDP wrote. It's a new lens that came out at 200 USD. In a few years, that price will drop significantly. This lens was not designed to compete with Nikon's 50mm f/1.8 S, which started at 600 USD, or triple the RF 50mm's price. The RF line used to be synonymous with great optics and high prices, but the RF lineup is filling up and becoming what the EF range still today, with something for a wide range of photography and prices. Not many people in this forum are going to go for the RF 24-105 f/4-7.1 either, but Canon is going sell lots of those 24-105s and a lot of the these 50 f/1.8s.
When the RP came out, people ridiculed Canon for not having cheaper lenses although it was a less expensive option for those with EF lenses already to see some of the benefits of MILCs. To maintain its market position, Canon needs a wide range of lenses catering to pros, enthusiasts, beginners and those on a tight budget. The RP with this RF 50 f/1.8 can do a lot of types of photography for a low price. Canon will also have better bodies and lenses for those that want to continue developing their craft with better tools. Maybe Canon will come out with a third RF 50mm lens, which is another discussion but does not diminish the role that this lens serves in the RF lineup. Most of the people buying and using this lens will not sport R5 camera bodies like the photographer in this video.
Will I buy this lens? Definitely not now, but maybe a refurbished one on sale. I have other options, so I'd really only use this to serve as a "pancake" normal when only carrying a telephoto like the 100-500 (the same role that my EF 40mm did).
