Quote:Brightcolors, the materials do not dictate the price of a lens. If this lens were made just of BK7 you could make all of the optics for $200 or so. LaSF materials or glasses to the left of BK7 will drive up the cost, as will aspheres, but there are mechanical difficulties to consider - centering such a beast will be monstrously difficult and will be a huge driving factor on the price. There is also the name-your-price aspect, as it is the only 11mm available.You can't make a low volume, complex lens like this with such complex elements "for $200 or so". The costs of producing the elements are far higher than just the raw material costs.
