Foveon Fotos

2002-02-26 Thread Butch Black

If in fact Foveon did give Sigma a 5 year exclusive digital camera rights to
the chip, they probably shot themselves in the foot. The market for prosumer
digital SLR's is for a long time going to be dominated by Nikon and Canon
shooters looking to add a digital body to their kit. Also, in reading some
early reviews in DP review, lens quality will be much more important as the
pixels, or quality of the pixels, goes up. I don't know that Sigma has that
many outstanding pro oriented lenses available, or that consumers will want
to spend that kind of money on pro level Sigma lenses. Sigma will definitely
sell some digicams, but I doubt that they will out do the big three.

Re: Re: Foveon Fotos

2002-02-26 Thread T Rittenhouse

Your point is well made. Also, the larger pixels are more sensitiv (higher
ISO) and less sensitive to noise (better image). Between those and your
comments about lens resolution a 24x36 would be far better than a smaller
chip with the same overall pixel count. A 6MP full frame sensor is pretty
much the same as what is being used in medium format digital backs right
now.

Let that be a lesson to the pixel counters; there's a lot more to image
quality than just the number of pixels a camera records. People who think
the Foveon (or the Philips or the Fuji or whatever) won't equal 35mm film
because it doesn't capture enough pixels are missing this. Of course those
who say it'll be *better* are probably missing it too. The proof or lack
thereof will be in the prints.

I'm really curious about these particular new sensors but the one I'm most
interested in is actually the oldest: the Philips. A full-frame chip gives
you more than the advantage of being able to use wide angle lenses. It gives
you the full resolution of your lenses. Consider two CCDs, both producing
6 megapixels, but one being full-frame and the other being smaller. A 35mm
frame has a diagonal dimension of 43mm. If you use a CCD with a diagonal
of, say, 28mm, you gat a "focal length multiplier" factor of about 1.5 with
the smaller chip. Now say your lens has a resolution of a nice round figure
like 50 lpm. That works out to 1400 lines across the frame of the small
sensor. A full-frame sensor, however, with *the same lens* would get 2100
lines across the full frame. In other words, the smaller CCD not only multiplies
your focal length by 1.5, it *divides* the effective resolution of your
lens by 1.5. The pixel giveth and the pixel taketh away.

This assumes all things being equal, of course, and all other things are
never equal. There are plenty of other ways to screw up a chip, so rather
than predict great things from the Philips CCD, I'm going to sit back and
wait to see how things shake out. Like I said, I'm really curious to see
images from this latest batch of sensors.

If they do, they certainly will.

I do not, however, find such an agreement very wise move from the Fovean people.
Maybe such a deal is for the current chip model used to build a 35mm digital camera ?

Hmm...
