5D III question: is there clean live ANALOG output?
 

I need to do streaming video for a client that is currently using, I believe, a Grass Valley ADVC110 A/D converter from a consumer grade video camera with composite output. I know the HDMI is not clean, but how about the analog? I could use the 5D III if it at least has clean output on the composite cable. Will it record HD while sending a clean composite SD signal? Thanks!

To leave any door open, I need a camera system that is VERY good in low light that can capture HD yet also do an occasional live web stream. The Canon C300 is not in the budget and I would like something that has both a good low-light sensor and nice selection of fast zoom lenses like the Canon f2.8 24-70mm. I'm not so sure the Sony Super35 sensor cameras are a good idea as their E-mount zoom lenses are f3.5-5.6 instead of a constant f2.8.

Don't know about the 5d but the 550d and 650d uses the USB port with an A/V adaptor on the end. There should be one with the 5d when you bought it.

I have yet to purchase a camera for this job and I need to know if the usb-analog composite output has a clean SD signal that is suitable for web streaming. If it also has a white box, like the hdmi signal, then this camera is not useful in one very important way.

How about the ? It has a clean HDMI out.

As a side note, the line skipping from DSLRs make SD video almost unacceptable for professional work. If you're aiming for SD, record HD and transcode in real time with something like .

Even better would be the new Panasonic GH3, but it isn't shipping yet.

Thanks, Donald and Sareesh. I think I'm not going to recommend a dslr for video since the audio workflow is more time consuming. The line skipping isn't as much of a problem for the 5Diii, and I thought its 35mbps vbr would be vastly superior to the 24mbps of the Sony FS-100 but that doesn't seem to be the case from videos I have watched. I found out about the metabones EF-NEX adapter that will allow a nice assortment of lenses to work with the Sony FS-100 so I think I am going to recommend that camera instead. I was concerned about the lack of professional quality NEX lenses but that doesn't seem to be an issue with all the adapters available. I still want a 5Diii for my own photography, but I think there are better solutions for a video workflow now.
