Poll: Most Wanted New Lenses of 2013.

[tron]

I would LOVE to see the return of DO lenses, Got to use a 400 f/4 DO today and it was a joy, the contrast/color is a bit off but super easy to fix in post.

+100000 !!!!

I would be interested but this lens' IQ has been controversial.

Some say it is very good, some not (some determine 2003 as the make year that made the difference.

I remember correctly at the-digital-picture site the 400DO didn't take the teleconverters well (IQ wise).
