F5: New 4K XAVC SONY PXW-Z100 for under 5000 Euro ?

so is that aliasing, or sharpening, some of it, especially the Christmas lights on the window plants, could be interrupted that way.Notice that the sample does not have traditional aliasing brick buildings, etc. But I need to see it on my editing monitor, and not my portable, so I can't really tell. someone please help. is my mobile screen or is it in the video?

I didn't see aliasing. I saw really well done sharpening. Despite that it was pretty amazing even at 1080. I can see this being of interest for doco work but I would still want a built in EVF a la EX3... and be willing to pay for it but no crappy new digital connectors from the camera to the EVF.

There is no way you can judge aliasing of the original from a down converted and compressed version on the web. Artifacts are far more likely to be due to the web version than any aspect of the original.

Valid judgements can only be made by looking at the 4k footage on a 4k monitor. (Though pixel-pixel framegrabs may tell a lot.)
 
I sure hope This isn't continued to be marketed as a near 1/2" camera... quite misleading and quite disappointing to see.
 
Anyone know if the two memory card slots can be written two simultaneously while recording? They mention relay support, transitioning from one card to the other when space runs out, but I'd prefer an instant backup where its recording to both memory cards all the time.

Good question - I don't know for sure, but the spec says "Multiple cards can be used in various ways, such as for relay recording."

I'd be inclined to think that one of the most obvious "various ways" would be simultaneous, so I think you may be OK to be optimistic!

The PMW200 is three 1/2" chips. This new camera is a single 1/3" sensor (the chip is technically 1/2.3", but it ignores almost half the chip and only uses the central 1/3").

Barry, that's very interesting info... did you deduce that or did you hear that somewhere?

Thanks,

It's been discussed in other threads. It's fairly obvious, the lens looks to be directly imported from one of their other cameras, the available pixels used (8mpix out of 18.9 total) and the stated crop factor all point to it being a 1/3" imaging area. It can't be anything else.
 
I have a Sony HX30VB with a 1/2.3 sensor with 18.9MP. Is this the same sensor ? It will take video at 1920x1080 60i as well as still of 4,896×2,752 at the same time. The still and video images have the same field of view. I use as my holiday camera as it also has GPS and compass info in the file too. I don't think the video is an optical crop from the sensor on this camera I think it is interpolated just like all the final images from a Sony Exmor sensor. The sensor feeds the processor that creates the final pixels for still or video. There isn't a 1:1 relationship for the consumer/ prosumer Sony Exmor sensor, still or video pixels are always created from the sensor matrix larger or smaller. At least that is my understanding.
 
The focal length of the lens, and the associated field of view, are mathematically linked. The field of view gotten from this lens can only be accomplished with a 1/3" imaging area.

Perhaps your HX30VB has a longer lens, or a wider field of view than the Z100.
 
This is the info for the HX30VB Focal Length (35mm equivalent) : Still 16:9: 27.5-550mm / Still 4:3: 25-500mm / Movie 16:9: 27.5-550mm(SteadyShot Standard), 28-784mm(SteadyShot Active) / Movie 4:3: 34-680mm(SteadyShot Standard), 35-980mm(SteadyShot Active) The Active mode is the EIS on top of the OIS so is an electronic crop with interpolation I think . The 4k cameras are 29.5 to 590 equivalents.

EDIT: By comparison my CX700 has a 1/2.88 sensor with 6140K equivalent 26.3 to 263 F 1.8 to 3.4

Barry I understand that focal length is the distance ( or effective distance ) between the sensor and the center of the lens. I also understand the relationship to FOV and sensor size but where have you seen that information for these 4K cameras. Not being critical, I am interest in finding out as such a lot is set as "equivalent of " in lots of these specifications I want to find out how to read the information released. I initially had the impression that the FDR-AX1 had AVCHD recording but now that seems to have disappeared from spec and it may also wait until next year for that function like the PXW-Z100 though the SD card slot is there on both of them for that very function only. Notes have now appeared on the specs for FDR-AX1 saying 1. Update to AVCHD 2014, 2. Update to USB 2014, 3. Update to HDMI 2014. I my switch back my desires to the PXW-Z100 now !!!
 
To calculate the crop factor, you divide the "35mm equilvalent focal length" by the true focal length. Both numbers are published by the camera manufacturer. Then you can divide the linear dimensions of a 35mm sensor by the crop factor to get the effective sensor size. The Sony FDR-AX1 has a 4.1 - 82mm lens with a 35mm equivalent focal length of 31.5 - 630mm, so the crop factor is 31.5/4.1 = 7.68 at the wide end and 630/82 = 7.68 at the long end. A crop factor of 7.68 is indicative of a 1/3" class sensor.
 
The focal length I am using is 4.1mm on the wide end that was published in one of the hands-on articles. And Sony themselves say it's a 29.5mm equivalent (using the commonly-accepted term of 35mm equivalent, as in, equivalent to a 35mm full-frame stills camera). The crop factor from that is 7.2, which is exactly what one would expect from a standard-sized 1/3" sensor.
