Earliest Optura model with RGB Color Wheel Filtering?
Hey all,
What is the earliest Optura model that offers the RGB color wheel filter? From what I can tell, it looks like the 30, but I want to confirm. Thanks! |

The RGB filter goes all the way back to the original Optura. It's a feature that's been removed on some of the more modern Opturas for various marketing (read: corporate greed IMO) reasons.

All the way back? Interesting. So, how would the image quality of an Optura 20 compare to a 30 or something else current? The price difference can be about 50% between the 20 and 30.
Thanks! |

Oh yeah, I believe the Optura 30 has better still images. I've got a few examples on my site (downsampled to 800x600). Good luck, Philip Williams www.philipwilliams.com |

For feature set reference, compare the full spectrum of the Optura line on my page located at:
http://www.dvinfo.net/canonoptura/articles/compare.php For more details see also my Optura Lineage page located at: http://www.dvinfo.net/canonoptura/articles/lineage.php (although I do not yet have a descriptive paragraph for the Op60/50 -- but I'm working on it) |

Can anyone explain: what is the RGB color wheel filter? How does it actually work? Sounds like something that spins with a motor...
What actually makes it better than single chip cameras that don't have it? |

http://www.canon-europa.com/mvx30ser...ePageID=196706 The Optura Xi online PDF brochure has a marketing description of the filter as well. Hmmm... honestly I still don't really know what makes it so different/better, though the CMYK/RGB info on the European site probably makes sense. All I can say is that a primary RGB filter definitely works. I really think that 1CCD cams with the filter have superior color. Unfortunately there's a tradeoff, as the filter absorbs quite a bit of light. I think this is one of the reasons that the new Eluras with a less light-absorbing secondary RGB filter have better low light capability than the primary RBG filter equipped Opturas. And that's with a somewhat smaller CCD even. As an FYI for those not aware, Canon isn't the only manufacturer to use primary RGB filters (though they advertise it the most). I believe the Sony PC350 (and maybe other models) uses one as well. Philip Williams www.philipwilliams.com |

i am a happy Optura 20 owner. I mainly use it for skating, filming swim meets, water polo games, school events, and family stuff. I think I am out growing it though. Im going to get something better this summer when I can afford it.

Frame grabs?
Kevin,
Would you minding sharing any frame grabs or video so I could get an idea of the image quality of the Optura 20? A mix of subjects would be very helpful for my search. Thanks, Brandt |

Brandt, the Op20 was discontinued quite awhile ago -- it's two generations old now.
For more RGB vs. CMY info, see my page at: http://www.dvinfo.net/canonoptura/ar...ra70-2.php#rgb |
