I don't want to further the dispute between you and Dimitri, but I would like to say one thing; Dimitri is certainly not a "Internet troll". He has been a long-time Nikonian member and contributes frequently.
It is known by many members how passionate Dimitri can be. Myself and Mick (mklass) have debated Dimitri many times, especially anything that has to do with his beloved Nikon 28-300.
This is the season of peace and good will, so it is my hope you two can come to an amicable agreement soon.
