Originally posted by normhead My interpretation is right now the Sigmas need that recessed built in lens to do all of what they do.
I think having a single lens built and mounted specifically for each unit makes it easier to get pixel-perfect images. Every camera and lens is a little different. When the two are fixed together, Sigma can ship them out knowing that the two work perfectly together.
Still, as long as the focus is just right, I can still get pixel-perfect images with the SD1M and the 18-35mm. That combo is way bigger than a DP, though.
I want to know how the new structure of the next Foveon sensor holds up against the current one at low ISO. I'm betting the low-light performance will now be on par with a Bayer one, but what about the resolution?
The new chip doesn't have all the colors individually at every pixel anymore, which I though was the whole point of a Foveon sensor. I'm really eager to see how that actually affects the image.
