First question, why are DSLR ( >$1.5k ) much more expensive than Film SLR ( >$500 )?
What are some of the main reasons?
[1] Production cost of DSLR is higher than cost of film SLR. Besides the body with a mirror and a prism, DLSR also carries CCD sensor, CPU, LCD display, software. All these components add up the cost.
In top DSLRs, CCD sensor is the most expensive component, and its cost could be in thousands of dollars. The larger CCD array, the more expensive it is. For todays technology, the production cost of silicon chip is proportional to the forth or higher power of its chip area.
Example. D1X's CCD chip is 1.5 times smaller of 35mm frame linearly, or 2.25 times smaller by area. To produce CCD chip of 24mmx36mm size, it will cost at least 2.25^4 or 25 times more than to produce D1X's CCD.
[2] As other members replied, the cost of R&D is also greater for DSLRs. Film cameras normally stay on the market for 10-20 years. Digital cameras have lesser "period of life" of about 2-3 years. Because of strong competition, manufactures have to introduce new models of DLSRs faster, which keeps their R&D expenses high.
