First 200-400.... probably about $50,000,000 to build...
second 200-400, probably about $5000 to build...and canon probably makes around $2500 profit per lens
To make their money back they have to sell 20,000 lenses.... a tough target to hit.

I would 2nd is much more than $5,000 to build.  2-100 probably were closer to $25,000 to build.  As production was optimized, manufacturing costs decline.

COG does not matter to the consumer, except that we need Canon to stay in business.  What is your time worth?  If you do a COG analysis, even minimum wage is too high.

What matters is the aperture at the long end of the zoom.  The 100-400 is 400/5.6, meaning a 71mm diameter front element, whereas the 200-400 is 400/4, meaning a 100mm diameter front element - 41% larger linear measure, meaning double the area (and larger volume, too).  Bigger elements, a lot longer (and more costly) to grow the fluorite crystals, more robust engineering to hold the larger, heavier, glass, etc.


Double the surface and probably close to triple in volume/weight.

Price / lb (I know stupid measurement, but ..) is very similar for all the great whites and new non-specialized lens.  Go figure - real or simply an artifact?
