I'm not sure whether to be happy or sad. I've just recently purchased a 300mm f/2.8 and both extenders. On the bright side I've got a great lens at 60% of the listed retail for the new version, but this is the second time I've purchased an expensive lens only to find it updated within a year.


Looking forward to any review of the Canon Extender EF 2x III to see if image quality is in any way improved, that may be a worthwhile upgrade.
