Originally posted by photoptimist That so-called "Law of Supply & Demand" comes with a lot of assumptions about the product (that it's unchanging through time), the customers (they are unchanging in time), the currency (unchanging in time), and the rest of the economy (also unchanging in time). It's known as a ceteris paribus ("other things being equal") law. Actual markets are full of exceptions to this supposed law because of violations of those required ceteris paribus assumptions.
Unless today's model of camera is a perfect substitute for last year's model (LOL!), any change in prices from last year's model to this year's model means nothing about supply and demand. There are ways of correcting for changes in products (see
Hedonic regression - Wikipedia) where an analysis attempts to assign a value to the added megapixels, frames-per-second, ISO, pixelshift, etc. of the new model relative to the old one but it requires lots of data, other assumptions, and can suffer from flaws in statistical reasoning.
Price Elasticity of Demand works best to lower or limit price when there is a ready product substitute, so that Demand cannot overcome Supply. The converse also applies.
Brand-unique lens mounts, installed base of unique-mount lenses, new tech upgrades and
Brand Identification Preference, for instance, can create Product Substitution Friction (Barriers to Entry by substitutes), thus promoting Price Inelasticity of Demand of a new camera (supports a high price). In the case of the recent, mature camera upgrade cycle, the old model has remained a decent substitute for the new model (they’re not differentiated enough) so the old-model price may actually be driving the new model price.
IMO this has some bearing on Pentax’s decision to create a time gap between sunset of K-3ll and introduction of a new APSc flagship. K-3ll was possibly good enough to be a controlling substitute for K-3x. The replacement tech jump must be substantial and the secondary market must be cleared - otherwise the K-3ll could drive the intro price of the replacement body.
Likewise an MILC is a good but not perfect substitute for a DSLR. In that case I believe a combination of factors, compounded by massive excess Supply of DSLR’a (Capacity Overrhang) is driving DSLR price, not outright Product Substitution. Adding premium features to DSLR’s to maintain price is a rational response under the circumstances.
I believe Ricoh foresaw the overcapacity of DLSR’s in 2012 and has patiently waited for an opportunity to compete for market share. Perhaps their recent orientation to Reference lenses and inventive product features portends a more active product cycle at Pentax in the future, now that DSLR capacity is normalizing.
