Low Light - HD110 vs. HD200??
Apologies in advance for not doing my "homework" on this but I am in need of a quick answer and it seems like an issue someone has already faced and could provide a straight forward, simple answer.
So here's the question - in low light situations, would the capabilities of the GY-HD200 add noticeably to the picture quality over the GY-HD110 under the same conditions? I know the 200 has a better AD convertor and better signal processing but am wondering if this will lead to measurably better low light performance. Thanks so much. TVH |

No. However, if you shoot in 30p, you might want to try shooting 1/30th shutter.

So If you shoot 720/60p w/60shutter the footage will be darker then 720/30p w/30 shutter footage under low light conditions. Laszlo |

I just had a conversation with Jerry Cohen about this today at the San Diego JVC High Definition Seminar. JVC bills him as one of the leading technologists in HD. Acording to Jerry, the gain circuit is before AD conversion on the 100/110. Gain is added after AD conversion on the 200/250. This results in lower signal to noise ratio when gain is added on the 200/250 cameras. |

I would surprize me that they would make a circuit worse then better on a new model...

Anyone out there done any real world comparisons? |

If the question is sensitivity without gain, Jerry said they were about the same. For a more direct comparison, maybe someone with both cameras can respond. |

Terry, chances are pretty good that you already read Stephen's comparison of the two cams, but just in case you didn't - http://www.dvinfo.net/conf/showthread.php?t=79436

If you mean less noise than a 100 with the same gain setting, yes. With just a quick pan around the room and checking different spots on the lit set the 250 looks better than the 100. Gain up, shooting into the dark corners, the 250 looks better than the 100. But it is hard to compare without both cameras back to back and no 100/110 has been set up at either presentation I have attended. One BIG advantage to the 250 is viewing HD-SDI out to a JVC HD production monitor. Both the monitor and connection are superior to my component to HD consumer monitor set up. So you can't fairly evaluate with the big monitor and the viewfinder/screen on camera are too small to give more than an impression. My impression is the 250 is better than the 100 (duh) and better lenses are better than cheaper lenses (duh). Further, my impression puts the 100 closer to the 250 than the other HDV cams I have used. If you have a 100 and don't need the new features on the 200/250, you don't need to put the 100 in a dumpster just yet. Tim Dashwood probably has done the back to back and may jump in with some acurate info. |
