First Test:
Zeiss ZF 25mm f2.8 v Nikon 24mm f2 AIS


The raw material from which this test was taken also includes comparisons of the ZF 25mm with the later (inferior) autofocus Nikon 24mm f2.8 prime and a number of other lenses, including the Sigma 20mm and Nikon 50mm. Download whole captures here. And thanks again to Frank for boldly going . . . .

As ever when viewing published tests, please check carefully the exact position of the focal plane: tiny inconsistencies so easily ruin tests like these, especially when assessing wide aperture performance.

If you're a Nikon shooter, the conclusion is irrefutable: as soon as it hits the shelves, run and get a ZF 25mm: it will be the sharpest and best corrected 24/25mm you've ever seen. End of story.

If you shoot Canon, however, you may already have been spoilt by the uniquely fast f1.4 L, or the astoundingly fine (and tiny) Olympus 24mm on an EOS adaptor. You might wonder how the ZF renders those all-important corners under the scrutiny of a more demanding sensor. You might have even read the 24mm World Cup in which the Nikon 24mm f2 was assessed on a full frame camera and convincingly bettered by the fast Canon, so you're thinking: the ZF is better than the Nikon f2 – so what? For you (and me) a conclusion would be premature.

But watch this space for a rematch of the 24mm World Cup Final . . . .




Draw a straight line and follow it.
