Zacuto Z-EVA-ERGRHDBP overview

  • 1Description

The Gratical HD Bundle from Zacuto Pro is designed to provide optimal balance and comfort while shooting handheld or tripod-mounted shots. It includes the VCT Pro Baseplate, EVA1 Top Plate, EVA1 Zip Trigger, a Top Handle with 15mm rod lock, Gratical HD Micro OLED Electronic Viewfinder, and Axis Mini EVF Mount.

The VCT Pro Baseplate features a sliding top plate for quickly removing the camera from the rig or changing lenses. It also features a built-in, curved shoulder pad, and a V-wedge tripod connector with 1/4"-20 and 3/8"-16 screw options. The baseplate has removable and extendable 6.5” iris rods and rows of 1/4"-20 screw holes along the sides for accessories. It has quick-release 15mm rod parts on the rear. The recessed rod mount offers maximum accessory mounting space under your camera lens. In addition, the baseplate also features a built-in M6 rosette.

The EVA1 ZGrip Trigger is an adjustable handgrip for the EVA1 Relocatable Grip. It allows for single-handed 360° rotation with the press of a trigger. You can flip it down for a sturdy handgrip and raise it up for an Aaton-style position. You can also flip it up to set your camera flat on the ground or for storing in a case. At the end of the grip is another M6 rosette with an included adapter specifically for the EVA handgrip. The adapter screws onto the EVA1 handgrip in place of the Panasonic flange. This modified flange allows you to attach the grip securely to the M6 rosette on the ZGrip Trigger.

The EVA1 Top Plate has a built in Z-Rail for adding the Zacuto Top Handle or Recoil Handle. You can reattach your Panasonic camera Handle to the plate. The top plate has a multitude of 1/4”-20 and 3/8”-16 screw holes for mounting various accessories. At the back of the plate is a 15mm rod port for a Zamerican arm or other 15mm accessory for mounting the Panasonic LCD on an articulating arm. If you need to attach top rods to your rig, you can add 15mm Z-Locks to the top plate for top rods.

The Top Handle features multiple 1/4”-20 and 3/8”-16 screw holes for mounting various accessories. The 15mm Rod Lock provides a side facing rod port for mounting the Axis Mini or a Zamerican arm.

The Gratical HD Micro OLED EVF features a micro OLED panel with 5.5 million dots of resolution for producing images with true blacks and a 10,000:1 contrast ratio to support 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. This 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. The optical path provides diopter that is adjustable from -1 to +4 and features an automatic light trap that can prevent damage to the EVF from accidental exposure to direct sunlight.  An ARRI-compatible rosette and a 1/4"-20 mounting hole provides a variety of ways to mount the EVF to your camera. The EVF can be powered from a single 1800mAh LP-E6 battery that provides a run time of up to four hours.

The Axis Mini is an ENG-style mount that is designed to attach to the top of your camera setup and provide you with ample room for adjusting focus or working with large lenses. It attaches directly to rigs fitted with a 15mm rod port and then connects with EVFs, such as the Gratical HD, using a secure 1/4"-20 rosette mount, or can also be used with 1/4"-20 screw mount EVFs with the separate Quad Rail for mounting.

Once attached, the Axis Mini's adjustable design utilizes four main pivoting points, which can spin a full 360° and are controlled using independent tension levers. With all levers unlocked, you can freely position the EVF using a single hand, or specific sections can be tightened down for fine-tuned adjustments on a single axis. Additionally, the articulation can be configured to work seamlessly with both shoulder-mounted rigs as well as for tripod-based shooting.

Gratical HD


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


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 Histogram 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 highlights the sharpest (most in focus) areas of the image with a color outline


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
