Just curious if anyone has any hands on knowledge of this extender. I see them on ebay (http://cgi.ebay.com …30066QQrdZ1QQcmdZViewItem
) a lot. They do not cost anywhere near what the Canon extenders do. I have been thinking about getting one but wanted to see if anyone could give any reason not to. Am I better off spending the extra money for the known Canon quality.
Thanks
Ed
