When I see people buying lenses that cover all focal range from wide angle to telephoto, I wonder is there a range I can skip? Can some one give their least used focal range and why?
I know normally the price goes down, but case in point, Nikon D90 has gone up in price in the last month due to lack of availability due to production being slowed and halted to make way for D7000. What are the trends of fluctuation in prices when this has happened before?
