The EX with its .14lux will certainly be better because of the larger sensors, but what it really means compared to 1lux of PD170, or 4 lux of the V1, or 3 lux of the Z1 - well, we have yet to see... |
my most crucial question is, will the hi-def broadcasters certify its usage? that seems to be the real acid test of cameras in this price range, in terms of maximum flexibility and maximizing the ability to deliver the product. does anyone in the know have any info on whether XDCAM EX will receive the same respect as its big brothers?

Certainly more sensitive than my Z1. Possibly a little more sensitive than my F350 according to the side by side test I did.

Sensitivity is F10 at 2000 lx.
To put this in perspective: JVC HD100/200/250 1/3" HD (720p) F8 @ 2000 Lux Sony XDCAM HD 330 1/2" HD Camera F9 @ 2000 Lux Sony XDCAM HD 350 1/2" HD Camera F9 @ 2000 Lux Sony HDW-750P HDCAM 2/3" HD Camera F10 @ 2000 Lux JVC DV500 1/2" SD Camera F11 @ 2000 Lux Sony DSR450 2/3" SD Camera F11 @ 2000 Lux JVC DV5100 1/2" SD Camera F13 @ 2000 Lux For those not aware, the larger the F stop rating at 2000lux the more sensitive a camera is. Sony have never published these ratings on cameras such as the Z1, but taking it is very similar in sensitivity to the JVC HD100 it puts it a Z1 at around F8 @ 2000 lux. One F stop represent double or half the amount of light. F stop numbers are not linear though, we have f/1, f/1.4, f/2, f/2.8, f/4, f/5.6, f/8, f/11, f/16, f/22, f/32, f/45, f/64, f/90, f/128 So taking f/8 and f/11 as a single full stop difference, the EX1 is about 2/3 of a stop more sensitive than a Z1. |

Having the options available is what make the format so robust, as you can switch bitrates based on your needs. Doing a no frills interview, use 19mbps, shooting boats on water use 35mbps. Price is relative more so to hardware than anything else, so I really see no benefit in "dumbing" the camera down to HDV standard. |
Thanks Guy
I appreciate breaking that down. This is very good news as it was a big factor for me. I hope the lower s/n ratio and this will mean really clean gain at 18db too.

Maybe I missed this in my reading, but does anyone know if the camera can down-convert to SD via Firewire out?
|
I think only via 1394 out, which means for pure SD work, you are going to have to shoot HD, and capture via 1394 or render in post back to SD.
This seems to be so lame, how much is a DV encoder to add? Certainly the 330 etc can record native SD to XDCAM optical disk and just copy the files across. |
Wow, sony really have pulled something out of the bag here, this camera is going to be great!
The one thing that is missing is dv.. which is a shame i guess, but downconvertings so easy now, especially if you're running fcp with a kona card, down converting on the fly is so quick. Hmmm, cant wait to see more pictures, the chip are sounding amazing, and i dont think anyones going to miss the LP mode. Sony really have listened to people and thought about this camera, well done. Loving that it comes with an 8gb card when you buy it. Now if the images look as good as the hvx i might be able to get over that 420 colour sampling and buy this instead of an hvx.. we'll see. |
Have a read at this article. http://www.dvuser.co.uk/content.php?CID=171
It appears to be only HD. A lot of questions will be answered here. |

"Using Panasonic's method of SD chips and pixel shifting means you have superior low-light performance [compared to ex1] by anything between 1/2 stop and 1.5 stops." Granted, he did review a preproduction model. |
Well it would be a tall tall ask for a 1920x1080 sensor to beat the sensitivity of a SD resolution sensor of only a few years old technolog.
I don't doubt that while the sensitivity of the EX1 will be less than the Panasonic (but still better than the likes of a Z1), the resolution of the image will be far superiour. Then, with this higher true resolution, 4:2:0 vs 4:2:2 sampling will be less significant. ie for each pixel the HVX samples, the EX1 will sub sample twice. |
And this is just one review, so no need to throw up our hands just yet.
