Nikon D5 + AF-S 85/1.4G Autofocus at Moderate Outdoor Distance

Get Nikon D5 at B&H Photo.

When working with a DSLR, the one thing I MUST have is the Zacuto Z-Finder Pro 3.0x, $125 OFF through 21 April. See Reader Comment: Zacuto Loupe: “amazed by the result” and my review of the Zacuto Z-Finder.

Shooting lens alignment targets can lead to a false sense of assurance—what about real-world outdoor shooting at greater distance?

I wondered how the Nikon D5 + Nikon AF-S 85mm f/1.4G might fare at moderate distance, which in all my past experience with Nikon DSLRs and f/1.4 lenses has proven to be problematic.

Nikon D5 + 85mm f/1.4G Autofocus Accuracy, Outdoor Targets

As it turns out, I need not make any adjustments to my theories about DSLR autofocus. Includes two examples as shown below with a reference frame plus 10 frames for each.

Disturbing: how does AF Fine Tune help if in one case the results are frontfocused and in another case at about the same distance, the results are backfocused? Yikes.

See the Sony A7R II + Sony 85mm f/1.4 GM version of this test.
