Canon's new 600mm f4 L IS USM III weighs about the same (3050 grams). The length is also about the same, and so is the price! They also now use fluorite. Talking about copying a page out of Canon's playbook!
The big difference is that the Sony apparently has 24 elements, where the Canon makes do with 17.
