Again almost too close to call. The Zeiss has a slightly more pleasing quality about its low end tones here, which are more solidly drawn, so we’ll let it sneak an extra point rather than call it a draw.

Perhaps the ZF 25mm has a little more ‘bite’ in these Zone B crops, but we gave the Zeiss the benefit of the doubt in Zone A, so I think we have to call this one a draw: both are superb.

The Canon just holds on to its extreme corner superiority, but even there this pair are now very close at f11. In the 17-19mm section of Zone C, the Zeiss is perhaps a fraction sharper, but bear in mind that its longer focal length is giving it a few more sensor pixels to render the meshwork on this netting. The Zone C point just about goes to the Canon, but it’s very close.
