Re: How can Sigma make sure the FFF is the best success it can be?

Actually I don't think I read your post carefully enough.

I, too, am not the slightest bit expert in silicon chip design and production. But my understanding is that standard production lines can only produce chips up to a certain size in a single step.

Jim explained the structure of the GFX sensor here:

However, although it is a tiled sensor, you are correct in that it is not made by making 4 small sensors and gluing them together. I think it's done by projecting the layout of the whole sensor in 4 separate exposure steps. It all ends up on a single piece of silicon.

I'm not sure whether the Kodak 14n sensor was done this way or whether it was literally separate pieces of silicon tiled together. But however it was done, you could see the joins in the files if you tried hard enough as thin black lines of missing data. That may just have been poor software not able to completely disguise the transitions, but the lines were there sometimes.

Things have moved on and I don't what the situation is with modern "full frame" sensors.
