Originally posted by biz-engineer The price of the sensor from Sony Semiconductors is the cost of the sensor for Sony camera's business. The impact of price for you (user) is the cost of the sensor + the associated margin. Therefore, for a given 50% gross margin at Sony semiconductors and 50% at Sony Cameras, an hypothetical double cost of the 42Mp BSI sensor lead to a 4x (four times) higher price contribution of the sensor in the pricing of the end product camera.To have an idea, an APSC sensor area is about twice the area of a Pentium processor, if the know the price of a Pentium processor. Basically, 1 inch sensors sell at about a few dollars, an APSC sensor sells at about $150 and a full frame sensor sells at about $450, but a BSI full frame sensor sells at $600 due to the number of additional manufacturing process steps required and eventually additional yield loss. An MF sensor selling price is about $2000 more or less. And I don't add the cost of the application process that you need beside the larger sensor. Now, add the margins of the camera manufacturers and see for yourself if what I wrote is crazy or not. About the pricing of a 300m2 silicon chip, please refer for instance to the price list provided here:
Intel Corporation - Processor Price List A few things are strange to me here. A K50 is selling for less than 300$... But the sensor cost to camera manufacturer is 150$. Still there the need to have the body, pentaprism, mirror, electronics, weather selling, SR... and the warrenty All the stuff. And the body need to be brought to B&H and B&H must make a profit. They are also proposing a 4% reward. So to me Ricoh can't really expert to make more than 250$ on it if B&H people are allowed to make some money. To me if an APSC sensor cost is 150$, Ricoh is simply selling K50 without any margin or at a loss.
It look more reasonnable to think that an APSC sensor selling price to camera manufacturer is arround 50-100$, maybe 150$ for a premium one you'd found in a K3 and even honestly this sensor is now 2 years old. But ok let assume it very premium and we take $600 price for BSI sensor.
Now go back to this K50 that selling for $300. Let's put a BSI FF sensor inside. Say Sony really sell for $600 the sensor, that 500$ more for Pentax for your computation. If they take 100% margin to cover all costs, that 1000$ more. They can sell their K50 with FF sensor for 1300$. If we think of it, it make sense: Sony is selling FF sensor for arround this price and they don't have to pay for mirror and use a "normal" non BSI senso but that give an idea.
Sure the mirror is a bit small and maybe the shutter is not good but it would work for taking APSC shoots. But I'am sure you could do all that with a comfortable margin and ask for $3000 in the end. That still 1650$ more.
So no really by your number I don't see any issue.
