Sigma 35mm f/1.2 DG DN Art Aperture Series: Rocky Creekbed at Dusk (Sony A7R IV)

Sigma 35mm f/1.2 DG DN Art

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.

Images up to full resolution plus a 100-megapixel version of the 4-frame focus stack at f/7.1.

The focus stacked image benefits from a world-class lens, something that eluded me with the Fujifilm GFX100, that is, even just one lens that made me satisfied that I was getting all that could be gotten from the sensor—never happened.

When I scale the 4-frame f/7.1 focus stacked image to 100 megapixels using Gigapixel AI, my impression is that the Sony A7R IV + Sigma 35/1.2 DG DN Art outperforms the Fujifilm GFX100. View the 100MP image and decide for yourself.
