@Vitaliy_Kiselev What do you think, that it's just this particular unit maybe? I wonder if they would potentially replace this one or at least try to repair it.

I think if anyone looked over this unit, it would appear to be in perfect condition, and would require a decent amount of time to test before the issue I'm describing was produced.

I talked to them in October about the issue, and they got back to me right away. I think they tried replicating what was happening to me but were unable to come up with a similar outcome.

One thing I have not tried, is using HDMI. I'd have to use a converter with the BMCC, but I have the Pocket Camera, which might be worth testing it on.

@fotosiamo: Isn´t there a 1:1 pixel mode?
The problem with the zoom-feature is, that it´s an interpolated / scaled image crop.
(So it´s better to use the 1:1 mode, if you´re outputting 1080i or 1080P to the monitor. Because then you should get a direct pixel output / crop of the image-center.)

Hmm. I don´t have an A7/r/s to check this by myself - But is it maybe the case, that the Sony body is changing the output as soon as you´re showing the camera info? For example: Without you get a full 1:1 pixel output (from the sensor / processor) - And with the overlays it´s outputting a 4:3 or an smaller image (as Sony is also selling such screens - For example the CLM-V55) - So the output fit´s that screen better.

The problem is, that I don´t know of a feature to crop the image properly - I just had the similar 663/O/P for about two weeks (in the past). Also try to check out the options on the buttons - Just long press them - Then you can set the feature you want. Maybe there is a manual crop mode (which helps you to stretch the image a little bit). Though keep in mind - It´s AGAIN a scaling - So it´s not helping to keep the most possible sharpness and image details ^^.

Well, after using this on a long gig this past Saturday, I'd give the CK700 a grade of B-. It works pretty well, but shooting a flat profile on my Sony a7R (yes, still saving up for the a7S), it's hard to really get a lock on what's in focus when manually focusing. The thin red line for focus peaking isn't that easy to see and it doesn't seem to be super accurate, too, since it would show up in areas that still looks a bit soft on screen.

I had to rely more on when moire and jagged edges comes up on screen, as well as a punching in either on screen (1 to 1 pixel works best) or on the a7R as a punched-in monitor.

On the other hand, I just love having the waveform and false color. Both worked out great in helping me keep exposure in check.

Also, I was able to fine-tune the colors on the CK700 to match my a7R, so at least colors seems right.

I just wish checking focus can be done better, since it is very critical.

After having used the CK700 HOX, I have to say that regrettably, the image quality is just not good enough to pull focus. It's not crisp enough around the focus area and the focus peaking seems a bit off for some reason.

Nevermind, it's not working with my GH4 either. I just confirmed the GH4 outputs to another monitor just fine, same cable. etc. It was just sitting for a few weeks and seems to have had something go bad inside.

@fotosiamo I found the 8x zoom feature very helpful for focus. Moreso than 1:1 mode or peaking mode. Look on the last page of the manual for the "shortcut" to programming the F keys. It's one of the choices there. Opps I just saw, you have been using the feature. Yes, it shows off how soft my nikon lenses are wide open and how good they are 2 stops darker.

You just hold down the F key for 5 seconds until the choices appear, select the one you want with the brightness know AND THEN select it by turning the Saturation knob to clockwise.

In your photo, what monitor mount are you using? I am really missing a screw hole on the top. Hanging it upside down & inverting the images is really not a good solution, if you need to go into the menus. They are upside down in that mode.

@CFreak Yeah, I'm not sure if 8x zoom is really that accurate either when it comes to sharpness. 1:1 at least gets you a clear look in terms of sharpness as opposed to just blowing up the screen to 200, 400, 800%.

In regards to the mount they are just several random pieces that I purchased from SmallRig on Amazon and fashioned together.

I actually don't like working off the CK700 now. It's just awful for reliable focusing. Waveform and False Color at least works well. But for color accuracy, focus accuracy, and exposure accuracy, there are better options.

I've now switched to the SmallHD 702 and it is Night and Day when it comes to working with a proper, professional field monitor compared to a cheap, off-brand monitor.

Yeah, it's just nit good for proper focus pulling, with or without focus peaking. For the price of the CK700, I'd rather get the Blackmagic Video Assist, since that is at least a much sharper screen.

Actually, among cheap 720p monitors it may do ok, but not compared to TVLogic 56w or a SmallHD DP7 or AC7, though. It's still not that great of a panel, and I just haven't mentioned how crappy it is since I rarely use it once I got into more studio-style ACing work where I have access to better monitors.

And this is all before I got the SmallHD702, which is obviously light-years better not only because of the 1080P, but because of its superior panel.

Still don't like it and if I were to do it again, I'd rather save up and buy a used TVLogic 56W instead.
