I got this so I can use EF lenses in my Canon R6 Mark ii and it works great. I have a heavy 70-200mm sealed lens, and the adapter holds it with no issues. I love the drop-in filter system, no more screwing on and off the filter. It's so much easier and faster and the filters stay much cleaner. It came with two filters, one is VND and the other is clear. Additional filters are available for about $80/ea. I ordered the CPL filter and it's nice. I'm very happy with this setup, would recommend.
