Only economists are silly enough to think their specialty is a hard science and can have "laws" of anything.
Even gravity, a much more accepted causal factor in our universe, is referred to as the "Universal Theory of Gravity". At least scientists have some humility about what they think they know.
Anyway, getting back to Pentax cameras. I will shortly be acquiring my first (working - the first one arrived damaged) Pentax DSLR (a K-r). I own a number of other digital cameras, both P&S and DSLR of other brands, but I wanted a camera which was small and lightweight, and had in body image stabilization so I could use a few used lenses of somewhat older vintage (I like older glass in my Nikon kit) to save money on lenses.
Anyway, the body comes with the kit 18-55 zoom. I want to add one or two other lenses for this camera, for travel use when I do not want to cart around my large and heavy and costly Nikon body and lenses. I would like lenses which are autofocus. My main interests are macro and telephoto/zoom. I'd like a lens that will provide me with the equivalent of 55-200 or 300mm (35mm equivalent) which will supply about 80-300/450mm with the sensor size factor considered.
My demand (in the supply and demand equation) is that it not cost more than $150-200 used (US or Canadian) in reasonable condition, so I am not expecting a very fast lens (f3.5 or 4 at the smallest zoom would do) nor am I expecting perfect optics, however, I'd like to avoid a dog. Doesn't have to be Pentax brand as long as it fits and interfaces with the mechanics and electronics of the Kr.
Does anyone have a suggestion of one or more lenses that might fit the bill?
Many thanks,

Quite true actually. If no one (the consumer) buys then it doesnt matter what the asking price is. If the seller wishes to sell their lenses then they must drop the prices. When it reaches a point that the consumer begins to buy the lenses then the price is set BY THE CONSUMER.Quite untrue actually.
If the consumer begins to buy in such numbers then the lenses become scarce and then the prices will rise. Again, the price is set BY THE CONSUMER.
It is called the Law of Supply and Demand and no matter how you and others try to say otherwise, that Law applies in all cases, no matter the product.
Cheers.
