So i've been reading about image sensors (much of it is way over my head) but I'm doing my best to learn and I'm curious about foveon x3 image sensors or at least the concept with regard to video. From what I've read (and much of that is written by foveon or sigma itself so it's hard to know for sure) this sensor or technology seems like it might provide some real benefits. They "say" that it records more color information than regular sensors that don't utilize their stacked pixel sensors as it captures light at different wavelenghts with the use of different layers of silicon within the sensor itself and thereby captures "full color" at each pixel location. This all sounds really good to me but I've looked and haven't really seen any extremely positive reviews of either the sensor or cameras using the sensors. My main question is whether this sensor or concept might make a ripple in video imaging technology or if there are limitations that keep this from being a serious option for sensors in video.

Sigma has announced development of two new mirrorless "SLR-type" cameras that accept Sigma SA mount lenses

Both cameras feature a Foveon sensor, and Sigma SA lens mount to accept Sigma SA (DSLR) lenses. There is a high resolution electronic viewfinder (EVF) on the rear, along with a wide screen. The two models both have Foveon sensors, with the Quattro H featuring a larger APS-H 1.3x crop sensor, and the Quattro features an APS-C 1.5x crop sensor.

Sigma has also announced a number of optional accessories, including a battery power grip (PG-41), with 200% more shooting time, an electronic flash (EF-630) with S-TTL automatic metering, a flash USB dock (FD-11) to enable firmware updates for the flash, and a cable release (CR-31).

Release date and price is yet to be confirmed.

Many understand the Foveon advantage: you can get a prize-winning, unforgettable picture, just once in a while, because of the aesthetic edge the sensor gives. The processors are slow; you'll have to convert the RAW to get that super-real look. You wait up to 6 seconds for the camera to write to its SD card. There's no video.

( I can imagine the Hitler-in-bunker subtitles film excerpt where the fuhrer invites all who want fast, cheap cameras with video to leave the room - and only two remain. This then, is for those two of us remaining in the bunker ;-)

The ~$600 DP1,2 and 3 series (Merril) produce fixed-lens shots which look as good as the (previously around $10,000) SLR Sigma SD1

Now there are the newer, boxy looking Dp' s in the ring as well- with pretty much the same sensor/processor as the big SD1. So nobody much bought the expensive SD1 one unless they were rich - or else sure of a certain job or shoot which would recoup the purchase price in one go - as well as come up with the winning shots.

But that's chanced recently; The same, once £5,3000 / $11,000 SD1 has starting popping up for sale at prices down by around 85% Off Now as low as$AUD1,400 !! (US$1250) Time to compare them again!

from http://fotogenerellinternational.wordpress.com/2013/04/10/comparison-sigma-dp2m-vs-sigma-sd1-30mm-f1-4/

Both the Sigma DP2m and SD1 are fine cameras which appeal to different target groups and which reach top forms under different conditions. The DP2m is a compact camera capable of astonishing image quality – the full format for the jacket pocket, so to speak. This compactness comes with disadvantages as well, lenses cannot be changed, one has to make do with a fixed normal focal length. The SD1 is equipped with the same Foveon sensor and performs similarly, but having a lens mount, it provides the possibility of changing lenses in order to be all geared up for any motif whatsoever. What happens, however, if one mounts the Sigma 30mm f1.4 onto the SD1, thus creating equal opportunities (as much as this is even possible with such different cameras) and let them compete against each other.
