Maybe such a deal is for the current chip model used to build a 35mm digital camera ? Hmm...

unless the big name players use their muscles and keep sigma out. In which case fovean could die too.

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.

Re: Foveon Fotos
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. Either we received different prints, or you need new glasses g. I'd have to pull out the prints to be very specific wrt each one. But I was not impressed one whit.

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.
