Zooms can suffer from pincushioning (at the telephoto end) and barrelling (at the wide end) but both issues can be easily corrected in editing software. Affinity Photo 2 (1), Lightroom/Photoshop (2) and DxO PhotoLab (3), among others, have lens profiles or manual tools to correct for distortion as well as other lens flaws, including vignetting and chromatic aberration.
