  1. I did not know this! So, technically, I can use an old Analog Bartech handset, to talk to a Digital Bartech Receiver with a digital motor like a Preston Motor?

    SmallHD 703 Ultra Bright

    I think the problem with the blacks is just inherent with using an LCD panel and not an OLED panel. Even the "black" pixels are being backlit (and even more so with the Ultrabright 703). I'm still waiting for them to update the firmware such that I can assign toggling of peaking and focus assist with one of the physical function buttons.

    SmallHD 703 Ultra Bright

    From my experience, now having owned the monitor for almost a year, it is quite reflective. As an assistant, it doesn't bother me too much because the problem really only crops up when you have a light source behind your head when looking at the monitor. And in those cases, I can always angle the monitor to remedy the problem. I really do love how bright it is, and the brightness can often compensate for the reflections. I rarely ever need a shade/hood over my monitor even when working outside in daylight. That being said, I can see this being an issue for a steadicam monitor. When you are doing your shot, if reflections become an issue, you can't just reposition the monitor on-the-fly to fix it. If the shot requires your rig to be at a certain angle or position, you can't just reach down and reposition the yoke mid-shot. But you can always put on a hood/shade. One other issue I had with the monitor is I've had needed two repairs thus far. One was for 2 dead pixels and backlight leak along the right edge. Another time, the monitor just refused to power up and required a new main board. But in both cases, warranty covered it, so I only had to pay for shipping back to SmallHD and they have been very good with customer service with regards to turnaround times. Sharpness and image quality is pretty good. It doesn't have the best colour reproduction, so don't use it for any colour sensitive work. I do like how it can take LUTs off an SD card, so if your camera is only splitting out a very flat image, you can apply a LUT to make it more contrasty. In terms of delay, I did some tests where I took a picture of the monitor hardwired to the camera (Alexa) photographing a timecode slate. It appears the delay varies anywhere from 1 frame to 10 frames with an average around 3 frames. I don't know why it varies, and I didn't have enough time to do a more comprehensive test.

    Rack Leaders/Framing/VFX Charts

    That's a great idea Johnathan. I found this product that essentially does the same thing: http://www.betterlight.com/zigAlign_options.html Seeing as how your method only requires a $2 pocket mirror, I'll probably try that first next time.

    Rack Leaders/Framing/VFX Charts

    This is a bit off-topic from steadicam-related things, and more of a camera assistant thing. With the prevalence of of VFX heavy shows, assistants are often being asked to shoot VFX charts and grids. Often times they involve shooting it with all the lenses in the package and depending on each focal length, you'll need to move the camera to an appropriate distance to frame the chart. My question is how do you keep the focal plane of the camera centered and completely parallel with the chart? This problem also crops up when you are required to shoot a rack leader/framing chart. I can mount the chart on a wall. But there is no guarantee the wall is absolutely perpendicular to the floor. The floor you set up the camera on may not be perfectly flat. I can use a level and level the camera and the chart, measure each of their center heights. But how do you ensure you are at the center of the chart left-to-right (even at distances of 20 or 30 feet), and ensure the pan/tilt of the camera isn't off-axis to the chart? With film cameras, you could shine a light down the viewfinder and project the ground-glass on the wall. But you can't do that with digital cameras. So, I'm curious how other assistants have done it. What is the method to maintain relatively high accuracy while being practical and not taking 20 hours to shoot VFX charts?

    SmallHD 703 Ultra Bright

    It does not turn back on once there is a power loss and power is then restored. Like the 702, you'll need to press the power button again to turn it back on. The boot-up time is quick, very similar to the 702.

    SmallHD 703 Ultra Bright

    So after loading the 1.5.1 firmware, I can confirm that the ghosting issues are gone. I'll take some pictures tomorrow that'll show if there are any hot spots. If there are things people want to see in particular about the 703, let me know and I'll take videos/images.

    SmallHD 703 Ultra Bright

    I received my 703 last Friday. I did notice the same ghosting issue as Walter. But I'll try the new firmware tomorrow on set and see if that fixes the issue. According to the changelog, it appears the original firmware is not interpreting P vs PsF signals correctly. And to respond to Jacek, the monitor is quite solid. Appears to be milled from a single solid piece of aluminum. Besides the joystick and buttons, I don't really notice any plastic on the exterior. The display is Gorilla Glass. But I guess time will tell how strong it is once they get out on sets and suffer some abuse.

    You're right. That doesn't make sense. I guess we won't know for sure until someone gets their hands on one and measure the current draw.

    SmallHD 703 Ultra Bright

    I spoke with David Bredbury from SmallHD this morning and he answered a few questions I had about the monitor. The 703 will draw about 12W-13W of power. Currently there are two 1/4 20 mounting holes on the back (one near the top and one near the bottom) and one on top of the monitor and one on the bottom. There are no holes on the side. They are working on a modular "cage" system that adds more mounting points. With the cage system mentioned, there will also be a shade available that can be mounted onto the monitor. The 703 uses a different molex connector on the back compared to the DP7-series. See the attached PDF file to see the wiring. David says the screw mounting configuration for the V-Mount and Anton Bauer plates should be compatible but for the Sony L-series battery plate, you may have to modify it a bit. Despite what videos on Youtube shows, the functions buttons can be assigned to specific functions and not just pages. Apparently heat dissipation shouldn't be an issue. They are aware of the heat issues with the 502 and David says this monitor runs cooler and it shouldn't be a problem. DRW_CBL-MOLEX8P-LEADS_A.PDF

    SmallHD 703 Ultra Bright

    Alec, when you got a to play with the monitor, is the zoom function exactly the same as the 702? I find the zoom function on TVLogic monitors far superior (in terms of sharpness) compared to the 702.
