    Hi folks,

    I thought you might be interested in seeing two Nikon lens designers talking about lenses. One of them designed the Nikkor DX 1.8/35.

    There are two passages that I found most interesting:

    @3mins, one designer described how he sees lenses as a way of compressing a 3D world into 2D and when parts of the 3D world won’t compress, then they become blurred. I’d never thought of lenses in that way before.

    @3:40mins he explains that for every stop increase in speed you get an increase in aberations to the power 3. Thus, from f/4 to f/2 is an 8x increase in aberrations. But the lens must not be 8x more expensive or heavy…these laws of physics are what lens designers have to work within. Fascinating!

    p.s. I wanted to post this in “Open Talk”, but that part of the forum seems to be broken.

    Anthony, thank you so much for posting this brilliant short interview. It is simple said truth, easy for everyone to understand. I am trying to promote idea that there are not better or worse lenses in general terms, just different lenses, such as we all have different eyes and perception.

    I will take a look at open talk to see what is going on there.

    Thanks again for your great contribution.
