Well I got a couple of the 2X's and a 3X off ebay . Ordered and received the male to male adapter rings=- like 7 dollars each from 2filter.com .
I finally pulled the pin on the 7D + 70-200 mk II IS , but I keep getting outbid on the mp-e 65 . [ I won't go over 700 on that lens used - couple more and I get a new one .
I am probably going to be busy learning the 7D anyway , but maybe someone will sell the mp-e 65 on ebay and since Xmas is coming maybe cheaper . Other wise , I will end up waiting .
