I love it

It works well on Sony a7rv with Canon TS-E 17mm f/4L Tilt-Shift Lens.

Works a treat with my Canon 100-400 on an a7CR

Reviews are quite mixed, but I could find few indicating using this adapter with Canon's EF 100-400 f/4.5-5.6 L II. I took a chance, made the purchase, and couldn't be happier with the result. AF is not instant, but acceptably quick. One can use both the lense's IS and Sony's OSS, but I can't say if the combination is better than OSS alone. I nearly always use a tripod, so that's not a big deal for me. Overall I'm quite happy with this adapter/lens combination.
