GY-HD family feature set comparison
JVC has just posted a page that shows the progession of features that are offered in the GY-HD family of camcorders. Many questions on this forum have been questions asking about the features differences between the three current models. This page shoud answer most of those questions:

Thanks Carl..
One of the features of the 200/250 is called out as "White Shading", an adjustment for different lens characteristics.
Can you explain what "white shading" does to the image? Thanks and Cheers |

Thanks Carl, I can see where the white shading adjustment is an important high-end feature for those who especially use some sort of prime lense set. I'm glad JVC packed a lot of great features into this small affodable camera. Hopefully I'll be able to bump up from my HD 100 to the 200 next year.

That happens with my HD100 and, as I recall, other people in this forum reported the same issue. My camera shades from magenta on top, to green on bottom (with the iris fully open). Is this fixable via firmware update? Thanks in advance, Sergio. |
I too have this same problem with the stock lens
a magenta tinge on top while a green on the bottom at an open iris |
I also have it when iris is fully opened, it's the only thing I really dislike about the HD100. Isn't it a chromatic aberration? This is the "standard" lens, it shouldn't happen.
So, can this issue be masked on the HD200? |

The original HD100 is supposedly set at the factory for white shading characteristics of the stock 16x lens. Here's more from a Sony white paper. http://www.dvinfo.net/conf/attachmen...tachmentid=373 |
Cross conversion
The comparison chart states in relation to the HD200:
- New cross converter outputs 1080i from live or recorded HDV Does it mean that the cross-conversion happens over the FW connection or only over the analogue component connectors? |

The HD200 doesn't have HD-SDI, though. And as far as 1080i out of the analogue component, the deck already allows for that so for people who already have the HD50 this functionality is not so important. If it were a FW conversion, that would be a different story...:-(

As well, now that 1080P LCD screens are becoming widely available it would be smarter to have the camera do the cross-conversion rather than the consumer TV. |
Do i have to take my camera in to fix this problem then, if I get the color shift? I\'ve seen it multiple times with the standard lens

If you can borrow someone else\'s lens and test it it would at least rule out faulty lens. When I connect the 13x lens to the HD100 there is virtually no white shading visible. My stock lens does show some white shading, but not as bad as some examples that have been uploaded. It is defintely worst when the aperture is fully open. F4 is sweet spot. |

Tim speaks the truth here and in other parts of this thread about how the quality of the lens does affect both chromatic aberration and white shading issues, as well as your iris setting and your zoom setting. The 16X "stock" lens needs to be thought of as an "entry-level" lens, thus there are some weaknesses. The fact is that all of our cameras have interchangeable lenses which offers the customer the ability to upgrade the lens, thus improving image accuracy and quality. The Sony link that gives the explanation of white shading is good information. I thought it also interesting that the article states that white shading is available on Sony\'s "high-end broadcast cameras". I suspect that they are talking about cameras in the $25,000 and up range. The JVC GY-HD200 and GY-HD250 units offer white shading at prices starting at $7995. Regards, |
