I was referring to the yield as in the percentage of items you try to produce that actually come out good. This is not something you can set. It is what it is. (But you can improve it by getting better raw material and/or improving production techniques.) OK, I'm sure Canon can do their bookkeeping in such a way that the sensor cost seems lower than it really is, but they'll only be fooling themselves in the long run. > Companies that have to buy sensors from outside companies don't get to > play those games. > They will pay a price that's governed by competition and/or perceived value, but that's surely also influenced by the actual production cost .. - T -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
