    Andy, curious if you have ideas on where lens technology goes from here?

    nice write-up, Andy, thanks :)

    my goto UW angle lens is my Samyang 14mm, f2.8

    I have been quite pleased with it's quality considering its affordable ~ AU$360 price tag
    particularly on wide angle astrophotography where pinpoint light sources from stars gives a good test

    Good question- although predicting the future is a fool's errand :) In general the trend is to larger apertures, reduced size/weight, decreased chromatic aberrations, and improved accutance. All of this is contingent on developments in optical materials- mainly glass- and the ability to grind aspheres. Incorporation of image stabilization is increasing as well. These developments all fall under "improved performance of existing lens designs".

    Something more 'exotic' I'm interested in is 3-D PSF engineering. That is, rather than simply design improved performance in the focal plane, the entire PSF can be designed- at least that's what is claimed for the new Nikkor 58/1.4. It's an interesting idea.
