     I never said that things are perfect or you need to buy Nikon lenses,  otherwise I wouldn't be using the G2 as opposed to the Nikor 200-500mm!

 

  However, you asked me a question which I think that I answered objectively, any manufacturer who designs lenses for his own cameras has a head start advantage......the knowledge of it's own system.

 

                               ........what goes on with TPMs and reverse engineering is another story and we are seeing plenty of great results from those too.

 

    ......but Nikon knows 100% intimately their AF system and doesn't have to compromise things for other mounts........so if they can't get things right.........they only have themselves to blame!

 

   The 600mm and 500mm I was talking about was just about zooming on the same lens, the G2!......

 

       ..........a light gathering issue.
