The Canon EF 50mm f/1.8 STM, for years, was Canon's essential lens. The must-have prime, the camera bag completer, the one that everyone should own. Is that still the case in 2022, though?
Let me explain. First of all I firmly believe that every camera owner should, in fact, own a 50mm f/1.8 prime lens. Even if every other lens you own or intend to buy is a zoom, you should have a nifty fifty.
The reasons are obvious and well worn at this point, but in short it's the 'standard' focal length, it's incredibly versatile and can be used for a multitude of all-purpose everyday shooting situations, blah blah blah portraiture, blah blah blah same perspective as the human eye and so on.
Why the Canon EF 50mm f/1.8 STM in particular, though? Especially as a Canon EOS R5 user, shouldn't I be pushing the newer, better RF version?
Here's the thing: faster autofocus and increased sharpness aside, there's nothing the RF version does that my EF version didn't. I look at pictures shot on both lenses and I can't actually tell the difference. We get swept up in GAS and the chase for the newest thing, but the truth is that the EF 50mm didn't suddenly become rubbish just because a newer lens came out. It's still great.
And there's one thing the EF lens does that the RF lens doesn't: adapt.
I can use the Canon EF 50mm f/1.8 STM on my full-frame Canon EOS DSLR. I can use it on my APS-C Canon EOS DSLR. I can use it on my APS-C Canon EOS M mirrorless camera. I can use it on my full-frame Canon EOS R mirrorless camera.
So, is the Canon EF 50mm f/1.8 STM still worth buying in 2022? Unquestionably. It performs as well as it ever did, and you can shoot with it on more cameras than ever before. It is quite simply the most versatile lens I own.
