I see what you did with the title! <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/tongue.gif' class='bbc_emoticon' alt='

I'm in two minds about this... how much can we sacrifice for other benefits? If we allow lenses to have some easily post correctable flaws, can we get them smaller/cheaper or even perhaps more easily optimised for faster focus by less moving elements. But the price is certainly putting it in a premium position, so perhaps we would wish for more there.
As a side note, while I like the AF/MF design on this lens, and would love to see it on more, I fear they'll only do it on premium lenses.

The lens is not so small though, and not so cheap either...
Comparing it to the "ancient" Canon Ef 24mm f2.8 on 135 format ("full frame") this Canon is 1 stop faster (the Oly being 24mm f4 equivalent), the Oly is 43 x 56mm, the Canon 48 x 67mm. So basically a difference you would expect for a lens that is a stop slower.
But the Canon is much better corrected.
So I am not so sure here the "uncorrected" design has much to do with benefits in other areas... just a philosophy that they correct in software rather than in lens design.
