I am still no further along with learning a method of posting to the web page. I just have not had time. I hope to have more time this winter. I have used to converters with both the 20-200 2.8 and the 100-400 IS on a bogen tripod and head, I don't have them in front of me and can't remember the model. They were used in situations that should have been fine( such as on a road with no wind). Using the same lense without the converter gave me sharp pictures but I just don't have the reach I would like.

thanks
