I'm adding to my collection of Markins ball heads with the Qi20 and the BV-22 gimbal attachment. Deciding on which lever QR to get.
I have an RRS lever QR on another ballhead, and a Markins lever QR on my travel tripod. I'm a fan of the RRS QR but have had no problems with the Markins QR which is a newer device on the market than the RRS. Neither QR has been a problem for me.
All my L brackets are made by RRS. Just wondering whether anyone has experienced any problems over time with the Markins lever QR. which would tilt me to staying with the RRS.
Good news and bad news.
Good news: your choice is actually simple.
Bad news: you have no choice if you want to use the BV22.
I have the RRS lever clamp on my BH-40.
I also recently got the Markins Q-20i + BV 22.
The RRS lever will NOT close on the BV 22. Yes, it is the newer B2 AS II. Yes, I know RRS says it will work on a wider variety of plates, and specifically mentions Markins. And yes, it actually works on the other Markin's lens plates that I have. But it will not close on the BV 22. It does not even make it to the halfway point. I applied a lot of pressure (i.e., well beyond normal), and could not get it to close: the BV 22 is simply too wide.
I ended up going with the (Markins) screw knob. The RRS lever release is nice, but a screw knob release is not that much more clumsier or slower and not at all less secure, and, in my mind, the ability to use any plate without any issues, either now or two decades from now, beats the minor disadvantage in convenience.
(Of course, given that the Markins lever release requires a screw to be adjusted to accommodate different sized plates, I would not pick that over the RRS lever or any screw-knob release under any circumstances.)
Now here is some great news: the Q20i + BV-22 make for a really, really, really, really, really, nice system! I do not know if you have used any other Markins, but the Q-20i is my first Markins, and wow! It is simply in another class than the BH-40. I know RRS gets a lot of cult-like love. And maybe I would sing a different tune if I had the BH-55 instead of the BH-40. But, in my estimation, while the BH-40 is a (very) good ballhead, the Q-20i is a functional work of art, with almost magical buttery, smoothness and rock-solid strength packaged in a gorgeous body that could easily sit on a pedestal of the Guggenheim.
