Camera Labs reviewed the Canon EF 11-24mm f/4L lens, one of Canon’s optical masterpieces.

From the conclusion:

What makes the EF 11-24mm f4L USM really special is not just the range but the optical quality. It manages to deliver these massive views with impressively low distortion – so much so that if you’re careful to keep the camera level, you’ll enjoy perfectly straight lines and square geometry across the frame. Even better, details are crisp and well-defined across the frame and into the corners at all focal lengths and even at maximum apertures.[…] The results are spectacularly sharp and well-corrected sharp even when mounted on Canon’s highest resolution bodies – or indeed adapted to Sony’s best mirrorless cameras.

The EF 11-24mm f/4L is no budget lens, though. All this optical awesomeness comes at a price, $2,699.
