I think what we have here Is the beginning. Possibly all sensors will be built this way soon or perhaps not- who knows. Here is a bit of advice for Sigma-

1. Make a full frame version
2. Put it in a mirrorless style body
3. Use a lens mount that will take all brands (E Mount maybe?)

For what its worth, the sensor has me hooked but the body feels more like a technology demonstrator, one of those cars you see at trade shows that never actually get made because they are impractical. I will be shooting some landscapes and urban work with this baby, it is more than interesting.
