Autofocus Accuracy: Sigma 35mm f/1.4 and Nikon AF-S 35/1.4G using Lens Align and Fine Focus Adjust

In DAP

How much Fine Focus Adjust do the Sigma 35/1.4 DG HSM and Nikon 35/1.4G need for accurate autofocus?

This test used the Michael Tapes Lens Align target, handy for evaluating autofocus accuracy and making adjustments with a camera’s Fine Focus Adjust feature.

This test also shows just how much better the Sigma 35/1.4 is wide open compared to the far more expensive but optically inferior Nikon 35/1.4G.

Even if you’re a Canon shooter or a Nikon shooter not particularly interested in these two lenses, put this piece on your reading list, because the ideas apply to any autofocus lens.
