Sony 14mm f/1.8 GM Review vs Sigma 14mm f/1.8 Art: The best astrophotography lens!

Tony Northrup compares the Sony 14mm f/1.8GM to the Sigma 14mm f/1.8 Art DC HSM. They&the same price at $1,600, but the Sony is less than half the weight, significantly smaller, sharper (especially at the corners), has far better autofocus, and slightly better bokeh. This is the most landslide lens comparison I&ever done. The bad news is that the Sony is only available for Sony E-mount. The Sigma is available for Canon, Nikon, and Sony. So, if you&a Canon or Nikon DSLR or mirrorless shooter, the Sigma is still your only option.
