Diffraction is now smoothing out differences in resolution, though the Zeiss rendering style and marginally greater accutance delivers a more attractive capture once again.

Having praised the Zeiss so highly, it should be noted that the Canon 24mm L does extremely well even to hold its own in direct competition – but unquestionably it does. At f11 and f16, many wide angles (zooms and primes) deliver acceptable results, but none quite as fine as this pair.
