I have been using the nifty fifty RF 50mm f1.8 STM lens on my EOS R5 for over six months. I am finding it to be a very versatile, high quality lens useful for a wide range of usage cases.
Not only does it deliver excellent results but it is compact, light and remarkably inexpensive.
I find it ideal for documentary and people work as it puts me at a non-intrusive working distance from my subjects while at the same time having a wide enough field of view to give context to the photos.
Some reviewers and forum contributors have made disparaging remarks about this lens, although it is not always clear what was thought to be a problem. I wonder if some reviewers have difficulty believing such an inexpensive little lens could deliver such excellent results.
There are some obvious cost cutting features such as the lack of a stabiliser (largely irrelevant if you use a body with IBIS), a single control/focus ring, plastic construction (the mount is metal) and focus by moving the whole 6 element optical unit.
Reviewers have pointed out correctly that the far corners are soft at f1.8.
But the same reviewers show that by f4 the nifty-fifty f1.8 lens delivers results virtually identical to the 10x more expensive RF 50mm f1.2.
Some have opined that the out of focus rendition (bokeh) of the RF 50mm f1.8 is not to their liking. But I have made many hundreds of photos with the lens and never found the bokeh unpleasant in any way.
Anyway here are some photos made with the RF 50mm f1.8.
