Shootout: Sigma 14-24mm f/2.8 DG DN Art vs Zeiss Loxia 21mm f/2 Distagon: Twenty Lakes Basin, View Towards Mt Conness Drainage (Sony A7R IV)
This series pits the Sigma 14-24mm f/2.8 DG DN Art against the Zeiss Loxia 21mm f/2.8 Biogon on a far-distance landscape scene on the 60-megapixel Sony A7R IV. Includes images from wide open to f/8 at up to full camera resolution.
The Sigma 14-24mm f/2.8 DG DN Art is a state of the art design for Sony mirrorless and by all measures might be the best 14-24mm zoom ever produced. The sample tested here is significantly better than the first one tested, but still not very impressive at f/2.8 or f/4, but then hold on tight because it gets really really good. The Zeiss Loxia 21mm f/2.8 Biogon optical design was produced for Sony mirrorless in 2015, and it is a fine performer. And yet... we shall see.
Includes images from wide open to f/8 at up to full camera resolution, with crops and extensive analysis/discussion.
