Great shot Carlos. Keep 'em coming. That lens is a great lens once you learn how to use it! which you obviously have.
Right, I have not figured it out yet... Either did a veteran TPF'r on Saturday.

Wasn't taking a cheap shot at you JC...I had quite a learning curve with that lens also...and I don't think after looking at today's crop that the curve has permanently flattened.

Shooting with a 900mm lens(equiv) is a whole different ball of wax from shooting with 400-500mm. And that is the problme for me as it does great on my FF 6D. That extra reach simply magnifies the he11 out of the slightest twitch. For me it is 1/2000 to eliminate it, even on the tripod. If I use a remote then not a problem at speeds to slow for the birds. As I said, just need to work out the recipe.
