Sony PXW-X70 low light comparo JVC GY-LS300 and Sony FS700
 

For anyone interested I have just posted links to a purely subjective and I mean subjective, low light comparo of the JVC GY-LS300 against the PXW-X70 and the now aging NEX FS700. The links can be accessed on the LS300 postings where I have posted some test shots of the LS300 with a B4 2/3" lens.

Nice comparrison, Chris.

To my eyes, the JVC GY-LS300 is the worse. The Sony PXW-X70 performs about 1 stop better. And the Sony NEX-FS700 performs at least one stop better than X70 (so over 2 stops better than the JVC).

At first, thought it was based on sensor size alone. But the JVC should have performed better if that were the case.

On another note, Chris:

Just looking at your 300, I thought whether - using a step-up ring - it would be possible to use my Letus Elite 35mm adapter on the 200 JVC model? This would allow for a 35mm DOF on a camcorder with rather small chip, should it be possible? In which case, how about crop factors? What real-world length I'd get from say my vintage Canon FD 1.4 50mm?

Yes Ricky it's not always as simple as it appears on paper is it. Quite often real world results can surprise us. What came out of this pretty primitive unscientific test was not really what I expected to see but there again that was the objective of the experiment. In reality two candles is pretty low light. I can't ever recall having shot anything with that low a light level on any job but I must admit I was curious to find out what the results would throw up given the mix of cameras.
