parkmcgraw: Having buildt my own digital devices and many lens systems in some cases making the element groups, do not from the specifications, understand why this lens, a minimalist design composed mostly of plastic should retail for so much money.
A lens with less manual control, more dependent on power and with the removal of the aperture ring, less of a professional tool.
■One “F” Low Dispersion (FLD) glass lens...
All the elements are small in diameter, easy to work, not too hard to polish.
■A floating inner focus...
The lens has some close focus capacity, nothing new.
■Super Multi-Layer Coating...
Nothing new.
■A HSM (Hyper Sonic Motor)...
Nothing new, or expensive.
■Rubber incorporated...
Compensation for using low stacking tolerance plastic.
■Thermally Stable Composite (TSC)...
Better plastic, but still plastic.
■A rounded 9 blade diaphragm...
No pats for doing what you should.
■A newly developed USB dock...
Marketing gizmo, no value to optics. Additional $10 to the BOM?
Anyway... Park... Do you have one such lens for sale? How much? Pentax mount?
Dxo provides the best public measurement data on cameras and lenses. Hopefully this move will help both companies to publish test results and reviews faster.
