The following text is from Dpreview's Sony stand report :
"While we were there, a delegation from Carl Zeiss arrived to see whether its E-mount Cine lenses would work without vignetting on the VG900. Since its designs are essentially full frame lenses with a long throat to extend the lens away from the mount, it seemed likely that they'd work, so long as the throat wasn't too narrow (which it might have been, given the expectation that it would only be used with APS-C/Super 35mm sensors). Sure enough, the CP2 50mm T2.1 Macro could be racked through its focus range without any shading appearing in the preview image."

Yeah, that's what we've been talking about. I guess dpreview is surprised that the e-mount cine lenses work, despite being full frame, because of the narrow throat. Either way, it's pretty much non-info to me, since I'd assume they would work in the first place.
That's what I would assume as well. But it's puzzling that joychrise wanted to find out, yet he is planning to get the A99 instead. That's what confused me in the first place.
Sorry for the confusion, got my wires crossed a bit.
My question is whether the VG900 will allow you to shoot FF mode without the LAEA3 attached. There's no vignetting from the DPreview observation, but I still wonder if the camera defaulted to crop mode without detecting a FF lens.
Until they are available for testing I have some questions about this and a few other things. Sony has a history of blocking certain features on its "consumer" cameras to avoid conflicts with its pro cameras. And the VG's are a consumer line.
I'm going to rent one to tinker with once its available, since it'll be released before the A99.
I understand what you meant now. I certainly hope not, and there would be an outrage if that is the case. To me, all other pro camcorders don't really need to have a full frame; all top cine lenses are in S35 format anyway. So in that sense, the VG is not really competing directly with those guys.
Please do share your findings. I'm curious myself and it seems like Sony is not going to commit making any FF NEX camera soon. So the VG900 might be it for me.
The real outrage - for me anyway - is the fact that the VG line will not have the customizable picture profiles that the Nex and SLT cameras have. So you can't adjust contrast, sharpness and saturation, something my Nex5n can do and the A99 can as well. I find Sony's default sharpness to be a little overcooked - especially with super contrasty Zeiss glass - so I have to tone it down. Not having that ability has kept me from buying a VG camcorder and that will likely be the case with the new models. Hopefully there won't be any issues with adapted lenses and the crop mode. We'll see...
Well, far too early for anything conclusive, but that seems VERY encouraging from the 35/1.4 voightlander, which afaik isn't even made for digital sensors ?
The shot with the 35/1.4 is encouraging, although shooting at infinity will be the real indicator (and a non-cropped 3:2 frame.) FWIW, the Voigtlander 35/1.4 also had less color shift than any of the 35mm M lenses that I've used on the Nex-7.
This is really encouraging. Is it possible to confirm that the Nokton 35/1.4 example is covering the full image circle? Is it possible image stabilization is on, and therefore the example only represents the APS-C cropped centre?
If somebody lends me a VG900, I'm more than willing to test my CV 15/4,5 ZM25 & ZM35 and make an extensive report: Infinite, near focus, all apertures, corner sharpness, color vigneting ..
I'd be pleasantly surprised if the Heliar 15 worked fine, but I'm betting on the contrary...

i also volunteer to test my rangefinder lenses on somebody else's camera.

I thought the picture would be cropped a bit in video mode. But if it's not, and other WAs would play nice then this would be huge.
It's probably the 16:9 crop of the fullframe. Google translates the text above the two samples as:
"On the other hand, if you use a third-party lens and mount adapter mount adapter other than genuine, such as LA-EA2, but not only in the manual as well squeeze AF also, of course, it is able to use the entire charm 35mm."
Which seems to say these are at least not APS-C crops.
@ julian The VG900 does not have and built-in IS, only E-mount lenses with OSS.
Looking at the samples on Japanese site its pretty encouraging, it does seem to allow for the full FOV regardless of lens used. Interesting no AF when using the LAEA3, that's the first time I've seen that. I hope at some point soon we get to see some side by side comparisons with the A99.
Does the VG900 have digital image stabilization at all? If so, then Sony could be using a smaller portion of the sensor. Some of the NEX still cameras actually crop a little when shooting video in 16:9, rather than using the full 16:9 portion of the frame.
The lossless 2x digital zoom with any prime lenses for video seems like a nice feature. In effect, a 50mm is a 50-100mm zoom. Apperently the zoom rocker can be used for this digital zoom.
I don't know how much truth in this, but Andrew from SLR Magic disclosed that Sony actually used "better" microlenses on the VG900 due to the complain with the NEX-7. The link is here:
That 3dkraft blurb is pretty informative about some of the workings of the VG900. It answers a few of the questions I have. Still waiting for a full test.
BTW, the SLR Magic lens samples look really good IMHO.
