FS7: Sony 18-110 Lens Grip Idea

Hey friends, I used to own the Canon 18-80 Cine Servo Zoom and I loved using it on the FS7. The lens grip was perfectly placed and felt much more comfortable to me than using the FS7's handgrip. It simply felt natural. Also, the servo zoom was ultra fast and very responsive allowing for crash zooms for in-the-moment filming on doc shoots and events. I also really appreciated the manual focus. I felt the focus throw was perfect for filming run and gun shoulder shots and was easy to pull focus with.

Last year, however, I ended up selling my 18-80 and picking up Sony's 18-110 because the range simply made more sense for my line of work. I really like the lens, the image quality, the focal range, the lens hood, etc. I'm using it on a FS7 MK II now and it's a pretty slick setup. That being said, there are a few quirks with the lens that make it harder to work with than the 18-80, for me at least.

First, the focus throw is almost too long. I don't want a DSLR lens-like focus throw that's so short you can't pull focus with, but the focus throw on the 18-110 is so long that I can't by hand do rack focus shots very well. It's just requires too much of a turn to get from point A to point B. I know this is not something that can really be fixed unless I use a follow focus and whip, so I just have to live with it, but I do wish it was a little shorter.

Second, the servo zoom is very slow. You can only get a crash zoom if you zoom by hand using the zoom ring which sometimes isn't ideal for shoulder shooting, plus, sometimes I just need to pull in or out quickly during a shot and with this lens that's hard to do. It's also not very responsive. There's definitely a lag between pushing the servo and the lens actually zooming.

The last problem I have is that there is no option to add a lens grip to the lens itself like you can on the 18-80. This means I have to use the FS7's handgrip which feels awkward to me.

So, with those issues in mind, I had some thoughts on a solution. I understand that the focus throw is what it is, so I won't address that any further, but what if someone could design a handgrip that could somehow be strapped or mounted to the lens barrel that had it's own servo? It would almost be like the lens grip on the 18-80. If so, we could give the 18-110 a great handgrip for working from the shoulder without needing the FS7's grip and with it's own servo and motor, we could fix the problem with how slow and unresponsive the zoom is.

I love this lens and would be ecstatic to buy a grip like this for it if there was something out there that would work or if there was a way to build one. It would make my work so much easier. I'd love to hear your thoughts and ideas on the matter and see what kind of solutions we could come up with. Thanks!
 
Seeing as one can buy the Canon Servo Handgrip separately, how about modifying one of those to fit the Sony?

Well, the handgrip is just the zoom rocker and buttons. The actual servos are in the "box" on the lens.

Chrosziel makes an "add-on" servo box for the Fuji MK's, but it's doubtful it would line-up/fit. You could buy a standard "FIZ" motor and controls, but it may not be financially worth it.
 
I'm sure this is one of those things Joshua - where it is very specific to the type or style of work that you do - but for me personally, I haven't had a problem with the 18-110 servo. For crash zooms - the manual works just fine for me handheld. There is certainly a lag when using the handgrip... but if I want to creep in on something I usually either do it manually or have also had good results with using the small physical zoom switch on the lens itself rather than the on the ext arm/handgrip. Takes a bit of practice - but has less lag.
 
I use a microforce and J4 motor and my buddy uses a microforce with a Haden motor one the 18-110. It works great and you can get a perfect press fit for gear for the zoom ring from Followfocusgears.com who made it up custom for me but now he's got the pattern so it should be only $45. I don't know how you would attach the microforce for handheld work but i'll bet someone could rig it up. Probably will cost between $1 and $2K with used parts and its not easy to go from a creep mode to a crash zoom with the micro force. Also Really fast crash zooms won't hold focus on that lens anyway as it uses some weird software to mimic being "parfocal" and that won't handle a very fast zoom.
 
My old Microforce controller had a "Zap" button on the underside that made for a really snappy zoom when pressed. It gave you the option of doing fast focal length resets even when the controller dial was set to a slow creep...
There also used to be a nice holder for the controller - I think it was the Oppenheimer handle from Seattle - that might provide some easier rigging options.
 
I think the Oppenheimer stuff was just for tripod handle adaptation. And not cheap. I use a Zacuto kit with my Microforce, but I don’t think they make it anymore. The big problem is, the rosette on the mounting cradle is different than the standard Arri rosette(although it could possibly be replaced with minimal effort). Just for sh!ts & giggles, I tried rigging mine to one of my ENG cameras in pistol grip fashion years ago, and I didn’t really like it.

It’s too bad David Ford is no longer with us, because the Bell Rocker would be perfect for what you need/want and I’m sure he could have made it work with a standard FIZ motor and/or possibly even directly with the lens itself. Zacuto has been working on something similar for YEARS, but still have not brought it to market, to my knowledge.
