things like geometry and CA can sometimes be easily corrected in software. It doesnt necessary mean you would need higher quality control standards to produce lenses with more geometry error or CA, and there is no need to do these these in camera processes "on the fly", they could be background tasks, even intentionally delayed until the card is removed from the camera, or even done outside camera later .
Look, if you can reduce the size, weight, cost of ALL the lenses, by having a single body feature to correct them may be a future path they or somebody else pursues.

[434 lines, snipped] Computationally correcting the optics will be expensive in terms of time for the camera to perform the processing (several seconds); the lens reviews will be harsh, so going first on this would be bad for sales; the ability to correct computationally will depend on *higher* quality control standards in manufacture, since the information provided on each lens will have to be very accurate or you're just having the camera apply funky blur. I don't think there's an economic win in there anywhere. Computational correction makes a lot of sense for those cases where the optical design can't manage to get things precisely right, either because it's a kit lens or no one wants a 10 k USD 12mm Ltd. so they didn't make it. -- Graydon -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions. -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
