Foveon Fotos
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
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.

And the pics I received from Mike looked like crap, in that it was clear they were digital, highlights were burnt out, there was color fringing, and some other problems.

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.

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...
