60MP Sony A7R IV
Sigma 35mm f/1.2 DG DN Art

Aperture Series: Rocky Creekbed at Dusk (Sony A7R IV)

Shot with 2nd sample of the Sigma 35mm f/1.2 DG DN Art, one clearly superior to the first sample, maybe not the best possible sample, but quite good.

This series evaluates the Sigma 35mm f/1.2 DG DN Art from f/1.2 through f/11 a near-far outdoor landscape at dusk. A beautifully-sharp 4-frame focus stacked image at f/7.1 is included for comparison.

It sure is a chore lugging the Sigma 35mm f/1.2 DG DN Art around for landscape photography, particularly when f/1.2 and f/1.4 have little value. It balances poorly on the Sony A7R IV, so much so that I feel I have to constantly support the lens lest it swing around and bang something. And it takes an unfairly large share of the volume of my pack. But the results make the effort worthwhile.
