The aperture F/4.0 seems to go all the way through, unlike Canon’s own and frequently used Canon 24-105mm that gets darker at the far end. The images appear very sharp and clear and we couldn’t see any obvious chromatic aberration or softening at F/4.0. We were told it is made for 4K applications. Overall the lens feels very well manufactured and strong.
