I've had this lens a few days and have shot about 2,000-shots, with it mounted on my Sony a9 body. I'm comparing it to my Canon EF 100-400mm f/4.5-5.6L IS II. The image quality of the Sony and Canon is very close. Shooting wildlife, neither is leaping ahead of the other in IQ. I'll trust DxOMark when they say that the Sony is slightly better.
What is stunning, is the quick and accurate autofocus, even when using all 693-autofocus points of the a9. When I at the Sony 1.4x teleconverter, there's no slowing. It's amazing. The performance is an order of magnitude better than the Canon on a Canon body.
Someone was comparing to a Sigma lens. There's NO COMPARISON of the Sigma 150-600mm. The Sigma's image quality is several steps behind the Sony and the Canon. If you crop the shorter lenses to match 600mm, the Sony image will be sharper than the Sigma image.
Oh, did I mention, the Sony is noticeably lighter than the competing Canon.
Okay Sony, send us a 600/f4 G Master lens and I'll be totally crossed over from Canon.... Read More
