    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.

So yet another dilemma. My current 400 5.6 has been decent for me for a while. This is my go to lens when it comes to wildlife photography, which is my main interest. 400mm is the golden mean for that purpose imo. Gaining an extra stop of light and 4 stops of IS are more than attractive, as well.

So my question is: If 400 mm is the one you mostly use then would you go with the 300 2.8 II+1,4x or the 400 DO 4 II natively?

300 with both 1,4x and 2x converters is surely more versatile, but the 400mm focal length being crucial for me I might give the nod to the 400 DO II, which is still charming with 1,4x and OK with the 2x converters, respectively.
Any inputs would be appreciated. Thanks in advance.
