It's full time liveview, LOL. There's no optical viewfinder.

Hubert, we do all those things now. Terrestrial telescopes make use of the parallax from the rotation of the earth and the movement of the earth about the sun (stellar parallax). Orbital...

Weird. I remember growing up watching the LED become the number one display for clocks, and a common display for lots of other instrumentation from calculators to thermometers to the exposure...

You can zoom over an effectively infinite range by moving the sensor back and forth (it's a point sized sensor, it's easy) behind the modulator.

You can control bokeh by using a small array of...

Then you should have no trouble naming some of the innovations they've stifled

Faster processing speeds, better low light performance, better lens designs... Investing in a company is not "doing such innovation's [sic]" Yes, it it. True. Wishful thinking. The only thing...

Yeah. It's not like they came up with the locally buffered CMOS sensor or anything.

Or the first practical stabilization system.

Or a usable ring ultrasonic motor, as well as the first really...

> It would be sweetly ironic, would it not, if the ultimate art in digital sensor design actually used ideas from film emulsion technology

What's so ironic about that? A Bayer pattern sensor is...

What's the attitude, Kendall?

I mentioned two things, lowering costs and color separation. Cost wasn't just a failure, it may have been "the" failure, the one that sank Foveon. They used to market...

Layered sensors solve problems of video scaling: dramatically increasing low light sensitivity and reducing moire. They also provide the same benefits to liveview.

They simplify AA filter design,...

Indeed. That's the main reason to do it (something Sigma never cottoned onto. They should have been the first to put liveview and video in a DSLR, instead of ending up the only company that didn't...

Monochrome sensors are a stopgap. Somewhere up around 200-400mp (and don't say we won't get there, because we've gone up 20x, from 1.7mp on the first DSLR I ever used to 36mp on my D800) you hit a...

If you read Foveon's patents, you'll see that Foveon owns no patents on the "concept for" a layered sensor. Make a sensor with an alternating PNPN junction structure and Sigma will sue the crap out...

Foveon stopped having National fab their sensors and switched to Dongbu Electronics way back in 2006. (There was all sorts of interesting talk at the time, including allegations of arson and...

Even Foveon wasn't satisfied with X3. There's a paper by Dick Merril that calculates six layers as being optimal.

At the rate processing power and memory s growing, I can't see this RGB stuff...

I wouldn't call it "Foveon style".

Like I mentioned earlier, there was a lot of layered sensor art before Foveon. Sigma's patents are all about the diode structure they use in an effort to lower...
