What a nice suprise. I thought Sigma was done with Foveon dslrs and its selling point was gone as they were stuck in 14MP for many years.

After all those years of nothing new, they released a 46MP beast and its crop factor is now 1.5x instead of 1.7x.

Based on simple calulation, it should be as good as 30MP cameras that use bayer sensor tech. I wonder how it performs in low light and if they fixed color issues.

blah its not really 46mp its more like 15. if history tells us anything it will preform just like if not slightly worse then other 15 ish MP cameras, just like all their previous cameras with the 3x per layer hax

are you kidding me? Foveon sensors will does not "guess" missing information because it HAS all the information.

Bayer patterns has information every 4 pixels (2 greens, per every red and blue pixel) it takes 4 pixels to gather what one pixel does on the foveon sensor, and it guesses the information to interpolate all 14mp (or 21, or 24mp) of the bayer sensor.

Foveon? has every single bit of information on 1 pixel. so foveon is a TRUE 15mp sensor, while bayer, well, uses their 17mp as marketing. Foveon can interpolate too. It interpolates to 46mp. So they decided to market this as a 46mp camera, a la bayer.

didn't see that one coming

speculation is that olympus is building the body for them. it does appear to by olympus's AF system.

Also, it's the SD1. The DP1 was a huge disappointment for me. So was the whole Foveon sensor thing.

but we all know, in the end, the difference is probably miniscule. It always comes down to the photographer. How good he is with his vision, and photoshop. (unfortunately, seems to be a necessity these days in photography)
