Sharpness at 50mm

For this review, the sharpness test is carried out by photographing a real-world sample, rather than a test chart. The Canon TS-E 50mm f/2.8L Macro Lens was mounted on a Canon EOS 6D Mark II, which was in-turn mounted on a sturdy tripod. Exposure delay was activated to prevent camera-shake. Any changes in tone you might see across the crops are due to natural light changes during the shooting session.

At the centre, the image is sharpest between f/4 and f/11, but is still very sharp at f/2.8, and f/16. Sharpness drops off a little at f/22, being more noticeably soft at f/32. At the edges, you’ll find the sharpest results between f/5.6 and f/16.
