Not sure if this is also a problem with the GL1 and why it's a problem with the TRV900 - my understanding of optics/colour (which is not a lot) is that the 3ccd setup should compensate for poor focusing of reds due to the different focal points of red, green and blue?< This is a common problem, even on broadcast cameras. Basically, although the 3 CCD sensors pick-up the 3 colors separately, it is common practice to derive the edge sharpening ('aperture correction') from just the green channel. This works well for most scenes but falls flat on it's nose when you get a pure red object like a flower. Since the auto-focus is probably also driven from this same signal (ie optimising the green edges) then this will also suffer.

If so can you let me know the differences and/or which you preferred? I've done some side-by-side comparisons: http://www.2-pop.com/library/articles/1999-11-15-1.html - VX1000 http://www.2-pop.com/library/articles/1999-11-17.html - TRV900 http://www.2-pop.com/library/articles/1999-11-19.html - GL1 http://www.2-pop.com/library/articles/1999-11-22-2.html - All 3 compared (diese posts stammen von der DV-L Mailingliste - THX to Adam Wilt and Perry Mitchell :-) [up] |
