Price
The price of a DOF adapter ranges from tens of thousands of US dollars for a professional solution to less than a hundred by using parts available from a local hardware store. The pricing of a DOF adapter unit also depends on the material and technologies used. For instance, a relay lens system must be added if the adapter is to be directly mounted to a camera's body (bypassing the standard lens, as if on a Canon XL1 or XL2 and the Sony EX3). Also, a prism system that is used on some adapters that correctly reorients the image rightside-up adds to the cost.

Famous quotes containing the word price:
“One has to have run a household before one can know the price of rice and firewood, and one has to have raised children before one can understand a parent’s love.”
—Chinese proverb.
“The price of justice is eternal publicity.”
—Arnold Bennett (1867–1931)
“... work is only part of a man’s life; play, family, church, individual and group contacts, educational opportunities, the intelligent exercise of citizenship, all play a part in a well-rounded life. Workers are men and women with potentialities for mental and spiritual development as well as for physical health. We are paying the price today of having too long sidestepped all that this means to the mental, moral, and spiritual health of our nation.”
—Mary Barnett Gilson (1877–?)
