Luminosity in video camera
Hi guys, i need help from some of you..
I have a JVC-GY100 that i love, except the low light image capture..it`s horrible, and my question is:
Is luminosity more direct to the processor of the camera or with the lens we use? and if it is the lens how can i distinguish them? the EX3 XDCAM as an amazing low light images, i already try one and it blow me away, there is no better one in that rack of price in low light capture.
Do you think i get extra luminosity with a good lens? what is your advice?
Thanks, cheers from portugal

The size of the imaging chips is usually the primary low light determining factor, The EX has 1/2″ chips, the GY100 has 1/3″ chips, larger chips equal larger individual imaging cells in the matrix which means better light gathering ability, another factor in the imaging chips is how they are manufactured and material used, better glass equals better resolution, to increase the light gathering ability you have to increase the diameter of the lens for a given focal length, in inexpensive cams small diameter lenses are the norm but in higher level cams the lens is usually maxed to its best for the avialable economics.

Thanks Brian
Guess the size of CCD or CMOs really maters in great brightness picture..i give up buy a new lens, it`s to expansive and now i believe i wont get much more that i get it now.
