Mouting a Zacuto EVF in the front of the F3 handle

For those wanting a rock solid mount for a Zacuto EVF attached to the front the F3 handle, here are step by step instructions and the list of goodies to buy. I like using Ultralight Control System arms because once tightened, the clamping system still provides a certain level of friction allowing some degree of adjustment. I also listed Sony’s 3’ HDMI cable with swivel connectors. This cable is absolutely first rate and the swivel ends allow for a complete relief of stress on the cable, EVF and camera HDMI ports. This is a great doco style filming setup with the F3 sitting on the cameraman shoulder and the EVF in front of it (like most good camera designs…). Using a top mount on the EVF provides good clearance around the lens with easy access to iris and focus controls. The Cinelock provide for quick removal or installation of the EVF using one hand.

To better understand the system, I uploaded a series of pictures on Picassa here:

WHAT YOU NEED:
- Zacuto EVF
- Zacuto Cheese Stick (important as this provide top mounting holes on the EVF)
- Sony 3' HDMI cable with vertical swivel connector (very cool, Mfg Ref is DLCHE10V)
- 2 x 1/4" external lock washer
- 1 x 8-32 1-1/4" machine screw
- 1 x 1/8" 3/4" fender washer
- 1 x 8/32" lock nut
- 1 x 1" Hex chrome screw w/washer
- 1 x UCS (Ultalight Control System) 1/4-20 ball adaptor w/o stud
- 1 x UCS 1/4-20 ball adaptor w/stud
- 1 x UCS 5" double arm ball
- 2 x UCS new style clamps (15 degree side movement)
- 1 x Cinelock
- 1 x Manfrotto Nano clamp

ZACUTO CHEESE STICK MOD: The purpose of this mod is to allow for better tightening of a UCS ball adaptor w/o stud. Alternatively, you could use a UCS ball adaptor with thread mounted directly in the Cheese Stick threaded hole but this is prone to some degree of slippage.
1) Using a 5/16 metal drilling bit, enlarge one the existing Cheese Stick ¼”-20 threaded mounting hole
2) Use 1” Hex screw and washer to secure UCS ball adaptor w/o stud

MANFROTTO NANO CLAMP MOD: The purpose of this mod is to allow the Nano clamp to fit under the F3 handle and to prevent the Cinelock base to slip around by installing a fender washer that will come in contact with the Cinelock.
1) Cut a 3mm x 15mm notch on the clamp claw that will be on the left side of the camera (pic 9). That is the one with Manfrotto’s markings (see pic 8)
2) Smooth out cut edges with a file
3) Drill a ¼” hole across the clamp ¼” from the edge (pic 8)
4) Secure fender washer to clamp using 8-32 1-¼” machine screw and locking nut (pic 10). Fender washer should overlap Cinelock base a bit to prevent slippage. (pic 7 & 8)
5) Install Cinelock base using the provided ¼” machine screw into the Nano Clamp ¼”-20 hole. Adding a ¼” external lock washer between the Cinelock base (female) and the Nano Clamp will prevent slippage.

INSTALLATION ON F3:
1) Engage wide opened Nano Clamp at a 90 degree angle from the right side of the F3 handle front support post
2) Rotate Nano Clamp 90 degree counter clockwise so Cinelock wedge is in front of F3 handle support post
3) Tighten clamp
4) Screw UCS ball mount with ¼” threaded post in Cinelock wedge side (male) ¼” hole. Prevent slippage by tightening tiny secondary sunk hex screw on the Cinelock wedge
5) Attach UCS clamps and 5” arm to Zacuto EVF and Cinelock wedge.

Et voilà. Enjoy!

Andrew,

I actually picked one of those cables up at a local sony store, and I am in AB. I don't use it anymore.. If you want it, its yours, Just pay me shipping which would be a couple bucks, and as I say its yours. If you want it, just pm me,

I was considering it, it's a very nice product but I wanted to keep the F3 lean and mean. Also, I can remove the all EVF assembly and easily install it on one of our other F3s just by releasing the Nano clamp.

I don't know if your solution is "leaner" than Berkey type set up??
"Meaner" for sure... By the look of it, your set up is substantial in bulk and size (just to mount single EVF) and reminds me of all those DSLR monster rigs...
But, if it works for you- that is the end of the story...

Not sure what you mean... The only thing I added to the F3 is a 100g Nano Clamp. The EVF articulated arm would have to be used with a top plate too.

What I was wondering about was the ball arm being a friction set up, what happens when your face bumps the eye cup? Does the EVF need to be adjusted again?
 
No the clamps on the Ultralight Control System exerce an optimal amount of pressure on the arm joints to keep it steady still allowing some level of adjustment. So, depending how hard you bump into it, you may or may not have to readjust. Harder to explain than use...

Hi Ryan,

The cable has arrived. Thank you for your thoughtfulness.
