I always enjoy your reviews Richard, even when I already have the lens
.
I've been using it in L mount since December and agree with your summary at the end of the video.
Like you I would have liked Sigma to have worked a bit harder on size and weight, the hood is not a good design, (mine has stayed in the box and I use an old Hoya Rubber Screw in which gives enough protection for me), silly way to remove tripod mount, but I tend to leave it on for ease of carrying - all of those issues disappear in use, it's by far the best focussing telephoto I have used for L mount, and I love the IQ. I use it regularly with the 1.4 TC and note no loss of image quality or autofocus speed performance.
