With the advancement of the DO technology (see 400mm f4 DO II), it will make for an interesting lens (as "cheap", compact tele zoom).

Ooh, if it retains as small, or smaller size than the existing EF DO, combined with a future M body with "better" sensor phase AF, this could get very interesting for me...


  Are you sure it will be cheap?

I wouldn't expect it to be cheap, as long as it is competitively priced in class.
