Haha! You knew that Canon/Nikon would be good yet bought something else...It happens to be honest. It happened with me so many times that now I usually buy things which I want though I do ask my friends. I do it so much that my friends now says "Jay, we know you going to buy what you like then why asking us". I tell them, I know but I want to listen from your mouth!
Anyhow, good piece of lenses you got. Any chance of seeing some sample photos?
