Sigma FE 105mm f/1.4 DG HSM Art Examples: Alabama Hills (Sony A7R IV)

Sigma FE 105mm f/1.4 DG HSM Art Examples: Alabama Hills

I just love how the Sigma FE 105mm f/1.4 DG HSM Art delivers outstanding real (actual) depth of field. It makes a terrific lens for panoramas and stitched images.

I really should buy this sample, because it shows perfect symmetry and amazing sharpness, better than the sample I tested on the Nikon D850 some time ago, even though the sensor on the Sony A7R IV raises the ante to 60MP.

This 2 X 2 stitched 129-megapixel image surely contains more detail than I could have obtained with the PhaseOne IQ4 150 megapixel, that is, because of lens quality and depth of field. At about 1/10 the cost.
