Works Well
By Jon
Rated 4 out of 5

I feel like it should be gold-plated for the price, but after you get past the sticker shock it is a very nice piece of equipment. Very secure and sturdy with excellent fit and finish.
Big improvement

Just got the Kirk collar for my Nikkor Z 180-600mm. Big improvement! Installs easy with a large, glove friendly knob and fits perfectly. Allows smooth rotation in the collar but also cinches down tight. Integrated sling swivel is handy for when using a rifle style sling. The Arca plate is longer than stock allowing the user to slide it back and forth to balance on a gimbal if necessary . Highly recommended.

Can you attach Peak Design anchors with camera strap to it?
I have attached my PD anchors to a Magpul QD sling swivel. The sling swivel then snaps into the QD socket on the underside of the lens foot. The setup works well for me.
