What reviewers say

Both reviews find useful portability and quiet autofocus, while stressing dependence on digital corrections. Cameralabs praises corrected sharpness and value on EOS RP. OpticalLimits finds much weaker corrected 24 mm corners on EOS R5, with better results at lower sensor resolutions, and prefers the L zoom if affordable. Both note the limited background blur from its modest maximum aperture.
