View Full Version : Earliest Optura model with RGB Color Wheel Filtering?
Brandt Wilson May 9th, 2005, 09:15 AM 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!
Patrick Jenkins May 9th, 2005, 11:33 AM 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.
Brandt Wilson May 9th, 2005, 01:26 PM 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!

I believe (going totally on memory here) that the 20 has the digital "crop and stretch" 16:9 mode whereas the Optura 30/40 finally introduced a real (ie. anamorphic) 16:9 mode. If you need 16:9, the Optura 30 destroys the 20. If you only need 4:3 video, well, you'd want to carefully compare the manuals at canondv.com to see if there are any other worthwhile differences. I'm sure the 20 produces some really nice video.
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,

Kevin A. Sturges May 11th, 2005, 01:52 PM 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?

Here's a link to Canon Europe:

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.

Kevin Girard May 11th, 2005, 09:54 PM 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.
Brandt Wilson May 13th, 2005, 03:57 PM 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
Chris Hurd May 13th, 2005, 04:43 PM Brandt, the Op20 was discontinued quite awhile ago -- it's two generations old now.
