Originally posted by Lowell Goudge Maybe they can release a new lens, weith new components, and fully re-designed, but I doubt they can set up to manufacture old lens designs and meet the price.
for one thing the cost is kept down today by extensive use of plastics, much more than what was in the A and F lenses.
I am in the plastic business for the last 30 years and being involved with designer and engineers for many consumer products
What is very expensive is the injection mold for parts to make a lense.You have probably 7-8 plastics part and the tooling can cost probably for what we call a familly mold about $100,000+. And because we have different diameter that can not use it for all lenses.
Also the main plastic that is used in Camera and lenses is Glass fill polycarbonate or Polycarbonate ABS.
These plastics are not cheap either Cost is about $3.00 per lbs, You do not need a lot but you need a mold. Sometime for small volume machining is cheaper.
The glass is machine and that not the problem because the machining is all computerised
Very simple you need volume.
For the K-X camera , I count about 25 plastics parts. The injection molding tools are probably costing to do that camera over $1 millions. The die cast for the internal frame probably a few $100 grant.
That why they try to keep similar parts from one generation of camera to another
