Resolution (f5.6)

Performance at f5.6 (Centre Frame)

Because this is the 24mm final, I was confident of achieving superb captures from each lens from hereon in – and they didn’t disappoint. By f5.6, each lens is producing crisp, attractive images with bags of detail, credible plasticity and no significant gremlins.

But centre frame, the Olympus delivers Zeiss-like levels of microcontrast and detail. Performance here is on par with the all-conquering Distagon 21mm and in a different league from the Nikon zoom and the Canon prime, which still appears to be off the pace in the middle of the field. Down the wing, it’s a different story.

Exceptionally fine rendition by the Canon: beautiful colouring, and every stitch in the netting visible. Once again, the Nikon 17-35mm is slightly edged out by the Zuiko 24mm. If only the fast L was as good in the middle.

A second sample from the mid-frame, this time on the right side, shows that all these samples are at least properly centred. The Canon 24L maintains its advantage here, followed by the Olympus and Nikon in close competition. Moving on to the upper left corner sorts the men from the boys.

Stupid sun. If we concentrate of the mesh of the satellite dish rather than the brickwork, whose lighting variation makes comparison almost pointless, the Canon and Olympus primes are outperforming the Nikon zoom, though the 24L evidently extracts more high frquency detail from the corners than the Zuiko. To illustrate this better, let’s consider a different subject at f8 . . . .
