How do you find this lens?Is it botched optically between 50 and 100 (soft corners no matter f stop),as it was the case with T70-300?
My copy is good corners with the aperture wide open, between 50 and 70 is the optimal optical range for this lens, and the optical performance of this lens exceeds expectations.
Cross posted in Sigma 500mm DG DN f5.6 thread. A few of a deer behind my house last night. It was getting dark, so ISO 12800, 1/400 at f/5.6 with the A7RV in APS-C mode and a bit of additional cropping-
