So some initial impressions of the Z1.
Im actually presently surprised.
One issue that I had major concerns about, which has been discussed at length, is how noisy the unit it. I don't find that to be the case at all, but I'm comparing this unit to other Pro units, not to consumer grade units. Im talking about the unit at max laser power / "Turbo mode" as its been described, when the unit has been running for a while.
Yes is much louder than a RS600, and it is a little louder than my 5000ES at full power, but not as loud as my previous DPI Titan Reference. I don't find this to be a big issue, I just think its a matter of perspective. Guys who have been using big Pro-grade units would not find it to be an issue. Guys who are use to completely silent consumer grade units probably wont be pleased.
Image - No calibration done. Just out of the box settings, the unit looks really nice. At max laser power / Iris open / Natural Mode / D65 setting - I get 2671 lumens. I am running the unit at max laser / iris open currently, and it has a nice punchy image even on a 14' wide screen. This is for blu-ray SDR viewing. (Again I think this is really beyond the limit of what the JVC should be used for.)
I think the Z1 sweet spot, is going to be on screens that are in the 10'-12' wide range. This will gives you many more options in how to run the unit. Either by reducing laser power or by closing down iris some. This will also allow you to open it up more for HDR content.
The dynamic laser dimming is visible in both Mode 1 and Mode 2. There is some "Pumping" without question. Using Lawrence of Arabia, the very beginning where its just a solid black image with music playing, you can see the "Black level" of the image just going up and down, up and down. On my Sony 5000ES, this stays completely black. I think JVC can improve this, but it needs some work. There is also the issue that Kris Deering described, where there can be a quick split-second jump in brightness on certain scene changes from light to dark. Best way I can describe this, is that the Laser is just dimming almost 1/2 a second later than it should. This too can probably be fixed thru future updates.
I haven't gotten down to just comparing scenes directly between the 5000ES and the Z1, but when I compare both at "out of the box" uncalibrated modes, the JVC Z1 at max laser / iris open is basically equal to the Sony with the Laser power set at 50, on a scale from 1 to 100.
More info and screenshot to come shortly.
