Z-finder solution??

After substantial research, I bought an EVA1 with Tilta shoulder rig and Zacuto Z-Finder.

As pricey as the Z-finder was, I wanted to have a proper EVF for shoulder-mounted operating, and with a flip-up screen. Basically approximating the function of the nicely designed Sony FS7 EVF.

The problem quickly became apparent: the Z-finder locks in the LCD screen so it no longer tilts/articulates (which is understandable, since the Panny LCD swivel is not engineered to take the weight) but contains no alternative swivel point to allow tilting of the viewfinder, just a tilting of the entire bracket up and down. This is terrible ergonomic design. There is not even a rosette on the stock bracket to allow manual tilt and/or connection to a third party extension arm (there is a Zacuto replacement bracket with rosette, but it uses Zacuto's non-standard 1/4-20 screw rather than M6, so it won't work with third party monitor extension arms.

Meanwhile, the supplied Z-finder bracket, with it's 15mm rod receivers, is an absurd design that allows only two fixed forward extensions. To add insult to injury, Zacuto doesn't even supply a metal replacement for Panny's plastic 15mm stud...which flexes under the weight of the Z-finder.

ALL OF THIS was completely glossed over by the Zacuto marketing materials and by their marketing video, which implied that the Z-finder is a complete solution. It is not.

So, a nearly $600 loupe and bracket by the "Cadillac" of aftermarket doo-dads, and tacitly endorsed by Panasonic, is nearly useless without the following upgrades:

1. an Axis Mini for FS5 (compatible with EVA1) articulating monitor arm ( $450)
2. an EVA1 top plate ($195)
3. a "Z-rail Axis mount" ($130)

The minimum total cost for a properly-functioning EVF solution: almost $1400....for a loupe, a monitor arm, a cheesplate and bracket....unless I am missing something. That is pretty ridiculous. If I had known of the extra costs involved to make the Z-finder functional, I would probably have skipped an EVF and just gotten a SmallHD Focus.

Panasonic, are you going to plug this gap with a reasonably-priced EVF?
 
I use a Gratical X, which admittedly was pricy, but I have scopes and the ability to access the camera's peaking through SDI. I use it with an $69 SmallRig extension, mounted to a SmallRig rosette on a bracket I made. When I need the LCD (which is only occasionally) I mount it on the back starboard side of the handle.

Another solution is to spend less than half the cash you mentioned on a Z-Finder Pro, which I also have on another camera. I actually prefer the larger screen, and it does flip up. Downside is it's HDMI only, so you don't get the peaking squares...

This is a picture I posted a while ago. Unfortunately it doesn't show much of the the Gratical X, but does feature the simple aluminum plate I made to attach the SmallRig rosette and the extension (it's bolted to the three 1/4-20 holes in the top). On the EVF end I put two nylon washers between the teeth of the rosettes so the EVF will rotate up and down without needing to loosen and tighten the knob. I do need to tighten it occasionally when it gets too loose, but generally it works like a charm...

BTW, I removed the cover flap on the Gratical because it can be a PITA when you're working fast. I cover the eyepiece when I'm in the sun with a plug similar to the one on the Z-Finder Pro...
 
Hey Mark, I just got my EVA a few weeks ago, and thanks to the super heads on the EVA User group on FB, I had seen the guys there trying all sorts of solutions, but the best and cheapest one IMHO is the Zacuto BMPCC loupe. It fits right onto the EVA screen with the sunshade on too. I use 2 small pieces of velcro to secure it there, and is easily removable. Its really light and cost €160. No extra pieces of hardware required. I'd love a Gratical X but I really want to keep the weight and power draw to a min ( not to mention the cost ). I have a Focus HD on the cold shoe of the top handle as well. Couldn't be happier with this setup. I have a Shogun as well, but to be honest, I'm so happy with the internal codec that I'm slow to go whacking that on it along with all the cables and batteries.
 
Murph100, Would it be possible for you to post a picture of your Camera with the loupe attached? Can you judge focus with the loupe only?
 
Thanks for the heads-up on this solution. As I've already bought the EVA1 Z-finder, I'm inclined to try to make it work. But I really like the idea of lightweight and inexpensive! As I need reading glasses, the Z-finder requires a +3 diopter and two extenders. THe BMPCC solution would need to accomodate that, too.
 
I think it came with 3 different diopter lenses, I'll have to double check the box when I get back at the end of the week. You can see all of the screen, nothing obstructed. Evaluating focus with is if easy when punched in, but just ok when zoomed out, better off using the focusing squares imho or something like a Small HD Focus. Here are a couple of pics.
