Zacuto Gratical HD overview

  • 1Description

Rising far above the readily available generic EVF or LCD screen with a loupe magnifier attachment, the Zacuto Gratical HD Micro OLED EVF packs more display features and functions than is found in many much larger EVFs and on-camera monitors. At the heart of the EVF is a micro OLED panel about the size of your thumbnail with 5.5 million dots of resolution that produces an image with true blacks and a 10,000:1 contrast ratio, supporting RGB at 24-bits for vivid color rendition. You can choose to display a 720p image within the full resolution display of the OLED and then display the various scopes and signal displays outside of your picture area, which allows you to have an unobstructed view of your image while being able to see a waveform or histogram display of your image.

The EVF incorporates both SDI and HDMI loop-through inputs/outputs and can cross convert from HDMI to SDI. It also supports peaking, false color, and test pattern generation as well as LUT creation and import. You can also select to view/display audio meters. The unit features four user-programmable buttons for often-used menu selections, and supports multiple frame rates. Zacuto has designed the entire optical path, providing a diopter that is adjustable from -1 to +4. The optical path includes an automatic light trap that can prevent damage to the EVF from accidental exposure to direct sunlight. Incorporating an ARRI-compatible rosette and a 1/4"-20 mounting hole provides a variety of means to mount the EVF to your camera. The EVF powers from a single LP-E6 type battery, and this 1800mAH battery provides approximately four hours of constant run time.

General Features

The 1280 x 1024 resolution of the OLED allows it to display a 1280 x 720 image and various diagnostic displays without needing to overlay the signals over the image. You can adjust the position of your image and displays to what suits you best, or you can also choose to overlay the diagnostic signals on the image.
You can create and store LUTS within the EVF and apply individual LUTS to either or both the EVF display and the downstream video.
The OLED display and outputs are independent of each other, which means you can display the video signal with one LUT on the EVF and send the video signal with a different LUT to an external monitor. Likewise, you can display the various test signals and diagnostic signals either on both the EVF on a downstream monitor or either one or the other.
Weather resistant covers prevent moisture or debris from getting in open ports.
You can choose to display audio meters in the EVF.
LUTs, test patterns, scope displays, and other display functions can be displayed in the EVF or simultaneously on the downstream video. You can select to have the EVF and the downstream video display different LUTs and/or display functions as well.

Test Patterns & Diagnostic Signals

Scopes
  • The waveform provides an objective evaluation of your video signal. It displays the brightness of your image on an IRE scale, allowing you to see if your image will clip and where your black levels are.
  • The Vectorscope displays the signal on a graph so you can check the phase of your colors. The Vectorscope function also verifies and checks the overall tint and hue of an image.
  • The Historgram view allows you to see where your pixels are distributed in the spectrum of black to white, providing a quick way to see where your exposure values fall. You can choose to display the Histogram as either RGB or Luma.
False Color
The False Color feature provides under/over luminance warning by presenting the image as a series of color values representing exposure.
Peaking
Peaking highlights the sharpest (most in focus) areas of the image with a color outline.
Zebra
Provides a crawling black and white pattern overlaying areas that exceed the brightness levels you select.
Frame Store
You can store frames within the EVF to recall them at a later time. You can also adjust the transparency of the frame store and superimpose it on the current view when you need to align shots.
Test Pattern Generation
The EVF can generate color bars and a Macbeth color chart

    Zacuto Gratical HD reviews

    Gratical HD Micro OLED EVF is rated 4.0 out of 5 by 9.
    Rated 2 out of 5 by from Great EVF, But Empty Promises I would quickly change this rating to a five if it weren't for one important issue that I will note at the bottom. First off, this thing is a great viewfinder, super sharp, super contrasty, and displays what I think is a super accurate and solid image. I've used just about every major EVF from Arri/Red/Panavision/etc and this thing blows them away. Zacuto was not embellishing when they said it's the best EVF on the market. It has a solid construction and great feel, and buttons also have a great feeling when pressed. I get a few hours per off brand LP-E6 battery and even more with my Canon brand, and having SDI loopthrough and cross convert is great when using external monitors with my a7r. There is one MAJOR problem I have with the device and with Zacuto though. I bought this for the purpose of having a compact EVF to view 3D LUTs on my a7r because I didn't want a big monitor on the camera, and Zacuto STILL has on their site that 3D LUT support is coming in a firmware update. As of this writing it's been almsot 3 years since the gratical was announced and there is still not even a hint of 3D LUT support. I emailed Zacuto directly and their response was there is no release date at this time which translates to it may never happen. The same issue is also to be said for their promise of camera specific control cables for Red/Canon/Arri, however this was not something I cared too much about, but none the less. Because of this I'm giving it 2 stars because I don't believe a company should advertise significant features if they can't implement them within a reasonable time frame. Any piece of technology approaching 3 years old is on the verge of obsolescence, meaning that NAB 2017 will probably bring competitors who can produce a similar quality product with more features for the same or even less cost. If Zacuto gets 3D LUT support out before the Gratical turns 3 years old I will up this to 5 stars, because I truly think this is a fantastic viewfinder, however, if you're buying this because of a 'proposed' feature, then beware that it might never come to fruition.

    Rated 3 out of 5 by from Sharp, but has significant issues. First off I have had my Gratical viewfinder for almost a year and nothing makes you feel better than to watch the price drop on an expensive accessory that you invest in. Having said that I would not have liked being without it for the past year. I am glad for shooters that have waited and can get the gratical for significantly less money. First off, the gratical is very sharp and thats the foremost reason for me to shoot with it. As we all know setting and maintaining focus is difficult with large sensor cameras and still zooms. The gratical's sharp image does not quite make focusing easy, but it does make it much less stressful. The gratical is really well built, it has a very sturdy feel. Lets get to some negatives. The viewfinder magnification is a bit strong, so it is difficult to easily view the entire frame. Off axis color shift-when you move your eyeball about in order to view the frame the color will shift enough to blue or orange to make you think that your color balance has shifted. Built in Sony FS7 LUT is not very good. Very aggressive and is something that I have never been able to realistically use to judge the exposure and color. The soft user selectable buttons on the gratical do not always work and the gratical needs to be restarted to get them back in working order. Lastly and perhaps the biggest issue is burn in. The Gratical immediately after use began to get burned in from the data and image guides that are present in the output of the FS7. Burn in not only hurts your investment/resale, but causes issues on set with thinking you have a sensor issue or perhaps missing a sensor issue because you think it is the Gratical. The viewfinder is too costly and investment to have such a fundamental flaw. The gratical is perhaps the best viewfinder out there, but it has severe weaknesses that makes investing in one a bit of a disappointment.

    Rated 5 out of 5 by from Worth it. I preordered this in November. Just got it about a week ago. Put it through its paces this week. While I do think it was expensive, I think it was worth it. This thing is sharp. There's a lot of room to view your scopes. A lot of functions. Huge step up from the original EVF Zacuto made. Build quality is great. I believe it's solid magnesium. Cold to the touch. It's a little larger than I thought it would be but with the axis mini it works well and balances nicely. I've been able to use it with a variety of cameras such as Epic, A7s, and pocket camera. Works great. The function buttons are a little loud physically when you hit them. Make clicks. Wish this weren't so as you cannot use them in the middle of a quiet take...but not a big deal really. The one main issue I had was some function buttons not registering. But Zacuto promptly shipped me another next day to exchange thinking it was a bad joystick function but they figured out there was a weird software quirk. You need to press the button in to access menus and map buttons rather than just use the right arrow button. If you use the right arrow, it won't map the key you want when you press set. They have terrific customer service. I'll be using this EVF for the next foreseeable years for a variety of cameras.

    Rated 4 out of 5 by from Get Focus I'm an old school shooter who grew up in the Beta Cam days. Great cameras to shoulder and focus. I find these box cameras with add ons to be a hassle for shoulder shooting and focusing with getting add on adapters and rigs. As a freelncerI had to get an EVF that I could attach on the various cameras that are popular in todays production world. The Gratical works for me. Sure I have to have the necessary Zacuto adapters to make that fly but struggling to find focus especially with moving a target subject, with shallow depth of field that EVERY clients wants, regardless....you understand what I'm trying to explain... I'm sure. Yes this EVF is pricey but it can be used on several cameras. Should I decide I've had enough of this business and want stay home and bake cookies with Mommy, I can sell it and I have a broad market to sell it too. Now for my user feedback.....I found that using peaking only was enough to get and maintain focus, which I really like more than than a colored focus aid. The viewfinder image is the best, period. The overlays of scopes, etc.. that are usually found only on monitors, that are included with this EVF is fantastic. To be able to put these scopes either above or below the image is so good. I love not have that stuff interfere with viewing an image. How many times has an on screen display hidden an unwanted thing that is in the shot? too many times. I can easily customize the function buttons to the way I like for exposure, focus, etc... Now for the lack of 5 stars. The function buttons will freeze or lock me out of using them after a period of around 15mins of none use. I must then power down then power up the EVF to gain access to the buttons. There is no record light to confirm I'm recording nor does the Time Code number display sync with a camera, to use record run to show me that I am recording. Zacuto apologized for these issues and said that they were working on them and the bug fix will be in a future firmware update. I can live with that for now. The LP-6 batteries gave me maybe an hour or so of power, but I'm using the loop through to feed a client monitor so I expected to get a short time with them. The D-tap adapter for a V-mount or Anton brick works great and found I can get almost an full day of shooting this way. The Gratical is built tough, nothing plastic about it! I am very pleased with the Gratical regardless of the current bugs.

    Rated 4 out of 5 by from Excellent - except... At 2500 (3000 CDN$ which is what I paid), you pretty much expect a VF that is about perfect. This one is not perfect, but it's pretty close. Good - 1. Super sharp, amazing colour and highlight rendition. 2. Scopes, false colour - and very easily switchable 3. Very good anti-fog 4. SDI & HDMI pass through 5. LUT application (with option of pre-LUT scopes) 6. *Tons* of adjustments & options. 7. Little flap to protect from direct sunlight hitting diopter Not so good 1. Peaking good but not strong enough 2. Battery power: 4 hours of runtime ? Yeah right, try about 1.5 3. No 4x and/or 8x digital punch in for focus (like the FS7 or Kinoteknik) 4. Can't flip up diopter to use VF as a screen I'd give it 4.5 stars if I could. Main complaint is the peaking. I get that some people hate peaking, fine - I'm one of those guys who loves crazy peaking. The Gratical gives us a range from 1 to 6. It's good - but not as good as the good ol' peaking dial on the Betacam (remember those?) VFs, where crazy levels of peaking were always available if you wanted it. Doesn't make sense to me that they offer brightness, saturation and contrast adjustments that go way beyond any level of functional usability, but with something like peaking they max out at 6. I'd say let us go to 10 - or 11. Pixel to pixel is...ok...., but at this price they should definitely have a simple 4x or 8x punch-in for focus like on the FS7. Why they didn't include this I cannot figure out. When you use the pixel to pixel the grainy peaking function shuts down which makes critical focus on wide shots very tough. Strange oversight. Batteries: the one they include lasts about 1.5, maybe 2 hours if you're lucky. Good generics @ 2750mAh (running about half the Canon name-brand rate but not the cheapest Chinese eBay knock-offs) run 1.5 maybe a bit more. Where they get the 4 hour thing I have no idea. I'll try a Canon name brand and see what's up with that. The little guard-flap to protect from direct sun (easily removable) is another great idea. Outside it can be annoying when the da**thing keeps mushing against your eye when you go back and forth viewing, but so many times outside you just forget about the sun, and having that little guard there is a life-saver. Also be aware: with batteries (let's say you use 4) and a good VF arm / holder you're looking at the 2500 + about another 200 min for batteries, and if you use the Zacuto arm (great bit of gear) that's another 300. So count on $3K US for a full package. Tried using a small magic arm the first day and that was anything but magic & professional torture. The Zacuto arm is expensive but works great. This was to replace my Kinoteknik LCDVFE, and definitely MUCH better. The Kino was good, but just not sharp enough and the colour / light rendition was just not there. Hope this is useful.

    Rated 4 out of 5 by from Great quality, needs a slight feature tweak The build quality is excellent. The image is razor sharp and the options are solid. Having eight function buttons is fantastic. That's more than the FS7 I use it with! I have two assigned to LUTs, which are much easier to use on the Gratical than the FS7 (which requires digging through menus). The weak points are: -slow pixel to pixel zoom (takes a good second to process) -no 4x/8x zoom for quickly punching in for focus -doesn't support 3D LUTs, so you have to use third party utility to convert, which meant more money in my case (Lattice) -Can't show scopes full screen. They're a little small, but very usable. -The recoil attachment for the FS7 still doesn't let me position the Gratical precisely where I want. I want it closer to the camera, not further away. -The focus assist technology could be better. For example, the focus assist on the Odyssey 7Q is fantastic. The peaking and red line assist is average on the Gratical. You can set options though which helps. -I would prefer that zebras work more like they do on the FS7. On the Gratical you can't set a low threshold to 61% (for example) that stays on through 100%. You set a tolerance range and the zebra will show in that range. I've adapted though. My favorite feature are the function buttons. It is so liberating to be able to instantly access a feature with a button press. No menus, just boom, there it is. I wish every piece of camera equipment had more function buttons. There's a lot of customization you can do. You can have the scopes show pre-LUT image data or post-LUT. I only have them show pre-LUT, but at least there's the option. I also tested a Paralynx wireless HDMI with it and it worked great. I ran the FS7 into the Gratical and then Paralynx HDMI out of the Gratical to the Odyssey 7Q. I was initially concerned that I wouldn't be able to keep the Gratical because the FS7 unfortunately can only output 4K via SDI or HDMI, not both. Since I run SDI to the Gratical, that would mean the HDMI from the FS7 is useless (meaning no wireless HDMI ability). The Gratical saves the day in that regard. I would give it 5 stars if it had better focus assist. The image itself is razor sharp, but I need all the help I can get with focus.
