A wily photographer called Alexander Heinrichs shares four full size JPEG images (one of them is actually resized to 32 MP) taken with the Sigma 50mm f/1.4 DG HSM on the Sony A7R via adapter. These are the first sample images from this lens paired with a 36-megapixel camera.

The zip file can be downloaded here (155 Mo), and a “behind the scenes” video can be found on Youtube. I find the pictures of the woman more instructive.

A few images from the Sony FE 55mm f/1.8 are also included. Interestingly, a “cat’s eye” effect (optical vignetting at work) can be noticed with this lens, while the Sigma 50mm f/1.4 Art mostly avoids it. Both lenses are stopped down to f/2 − a full stop for the Sigma. A picture of the same scene taken wide open would have been nice.
