Hi Brian,

I trust that you are well.

I have found the Zacuto quick release arms to be excellent for tightening without rotating, and I really like the quick release.

I did some research into the Chrosziel and found a series of video reviews on a bunch of different follow focus units. One of the reviews was on the Chrosziel. In the course of the review/demo they showed how you could put the gear on the other side of the gear box. It was unclear though if the gear would be in reverse motion when you moved the gear ring from one side of the gear box to the other. I was hoping it would. Below is a link to the video review series of follow focus units...

I had a chance to use the GENUS follow focus yesterday and found there was a noticeable amount of lash (play) in the unit. You may be able to adjust this but it didn't leave me feeling confident about the unit.

I have a Zacuto rig as well but for many the cost is too prohibitive. When you factor in the arm and BOTH of the receiving bits, depending on the size of the arm and what the receiving bits are, you are into it for over 300 bucks and often in the 400 to 500 range.

On a whim I bought the IKAN articulating arm. It is relatively short and has a 1/4" 20 threaded bit on both ends. When you tighten the unit down it is very solid and it is seventy bucks at this point in time and light weight...

I plan on buying a few more to have on hand.

I have used screw threaded arms for years, and I remember from my assisting days that they were slow, unreliable and always worked loose. The Zacuto quick release system solves all of this. It is excellent. Expensive, but will last a lifetime.

Previous to the Zacuto system a couple of the top AC's that I work with had machined their own quick release arms (they just did it for their own benefit and never went into manufacturing). The quick release saves time and hassle on set.

(Also, I am sure the cost will not be an issue for Brian).

The zacuto gear will still be useful in 15 years time, I am sure that the F3 will be old news by then.

You can get rid of all the backlash in the genus superior, but it does me stripping the unit down.
