Yes, Sir..
I did quote other sites....isnt that what we were asked to do, we were asked to give our own reason why we thought Mr Don should replace his lens which at th bottom of my information I have done , and other than that we were asked for any supporting evidence and comparison details in supporting it, now Im not sure what I have done to offend you but answering I just did what I was asked and gave my opinion and replyed to the challenge question, I am truley sorry if I offended anyone
