Inflation, R&D, tooling, and low production comparatively sums it up.
Factoring in inflation the exact same lens would sell for 8k in todays dollars. If they were to remake it you would have to add in the costs of development for SR and WR and AF since that is they way they are rightly going. Also keeping with the low production numbers about 12K would be a good expectation.
Just look at what the FA 45-85mm would cost in todays dollars would be 2,700. So compare that to what it sells for now and it is pretty close. So consider even if minor redesign and tooling are required to produce it again now. So again add in the R&D for SR and WR plus the new AF, labour increases, energy price increase, new tooling, etc. I think it would fall into the 5k range for low production numbers. It's just how inflation works compounded with new R&D, tooling, and more advanced systems paired with low production.
The 25mm would have been probably the lowest production lens since the 600mm. All the sales of it have to pay back for designing the widest lens they have ever made for the system (compounding in that it was actually even designed for the FF 645 adding additional difficulty).
Look at Zeiss lenses for the 35mm, very high priced for what you get as prime manual focus lenses. Yet they still have significantly higher production.
If it costs you $50M to develop and you only sell 100,000 units then add on $500 per item. After the final all in cost (R&D, electricity, capital investment for manufacturing, labour, materials, etc) Pentax will want at least 15% back. Shipping costs. The seller with also mark the item up. If it is something that has a low turn around like low production items it gets market up higher to cover overhead costs of running the shop and paying employees. Then you have the import duties and sales taxes...
These aren't like tv's for example with super high production runs and ever cheapening technology. Or even close to Sony, Canon, Nikon for production numbers to spread out the investment costs on and the obvious everything gets cheaper with scale.
If this lens wasn't projected to be so popular and the 645Z wasn't so successful this new zoom lens would easily be higher priced.
