It is a new design (else it would still be a 14mm lens <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/wink.gif' class='bbc_emoticon' alt='' /> ).

Maybe I my question wasn't clear enough.
When they build a new lens design, do they start from scratch or can they start with something similar and modify it?
If they start from something similar, do you think they could have start from the 14mm design?
If they started with the 14mm, could they modified the front and keep the rear design ?
And could the strange complex distortion in the 14 mm could come complettly from the back desing ( so it would be in the 10mm too) or partially from the rear ( so would be less prononce in the 10mm) or from the front design ( could be completly gone )
I don't know the process of lense building, so sorry if my wuestion seem silly.
