• UPDATE



    The forum will be moving to a new domain in the near future (canonrumorsforum.com). I have turned off "read-only", but I will only leave the two forum nodes you see active for the time being.

    I don't know at this time how quickly the change will happen, but that will move at a good pace I am sure.

With all the big Canons having been re-designed with improved optical performance and IS - the DO stands out for its neglect.

Have Canon come to the end of the line with this particular lens? Is DO a dead end anyway - even though Canon regularly leak hints of "possible" new DOs to come. Or is that all a sham to keep the 400/4 production line open?

Clearly optically inferior to the 300/2.8 nevertheless it is mechanically well made and a comparative lightweight and still has a good following.

Surprised that Nikon haven't introduced their own sharp 400/4 to fill the void.
