The new Canon EOS R5 Mark II is getting plenty of positive reviews. Here is…
Canon EF-S 24mm f/2.8 STM, a Pancake with an Edge (DxOMark)

DxOMark tested Canon’s diminutive EF-S 24mm f/2.8 STM pancake lens. This small, inexpensive, and light weight lens for Canon’s APS-C DSLRs performs pretty good for a $150 lens.
Concluding, they write:
The EF-S 24mm prime also offers a notable step up in image quality compared to the standard 18-55mm Canon kit lenses, if you’re looking for a lightweight second lens option. Despite marginally worse overall results for Distortion, Vignetting, and Chromatic Aberration, the EF-S 24mm prime takes full honors for Sharpness with a Lens Metric Score of 11 P-Mpix compared to 8 P-Mpix for both versions of Canon’s 18-55mm standard zoom. Transmission is significantly improved, too, around 2 T-stops better than the kit lenses, making it a better option for low-light shooting. At 24mm, using the maximum apertures of f/2.8 on the EF-S 24mm or f/4 on the zooms, the EF-S 24mm prime is sharper at the center; stop down the EF-S 24mm to f/5.6, and resolution is homogenous across the frame, which is something the kit lenses can’t deliver.
