I still don't think stills lens manufacturers can hold their manufacturing tolerances as tight as the cine manufacturers. If they did their reject rate would be way too high, and that would greatly raise the price of the product.
For example, to increase accuracy of manufacturing from .001 in to .0005 in usually increases manufacturing cost ten times (according to the examples I have heard). AFAIK, there is still no cheap way to produce aspherics, except for molding, which does not produce good enough surface quality for critical work.
Also stills lenses have to be designed to be light and compact. Now I think that there are very many excellent performing still camera prime lenses. But still zooms are just not designed to do the same job as a cine zoom. Just look at the huge difference in size.
Personally, I'm surprised that RED can offer those two zooms (18-50mm and 50-150mm) for such reasonable prices. Rehousing stills zoom is a big engineering challenge. Check the price of the Angenieux Optimo and see if you still think $6K for rehousing a stills zoom is too much. It's a bargain. I couldn't even get you one used Super Speed Mk.II for that amount of money.
Good glass ain't cheap. And the RED ONE requires good glass.
I'm looking forward with anticipation for the RED primes and the 18-85mm.
