Dear Good Folks
I am writing with a pesky question that may be of interest to many of the folks around here...I am looking for information about the Canon 1.4x teleconverter...this would be used with the 70-200 f4 and the 300 f4 only, in my case. Is there a noticeable difference between version II and version III of the same teleconverter? Either in AF speed or IQ?
At the moment I'm using the Kenko Pro 300 teleconverter, and I assume (perhaps incorrectly) that the Canon model will be a step up?
Any information you might have would be so helpful...please bear in mind that I've already read countless reviews online, and am looking instead for HANDS-ON EXPERIENTIAL information...
Thank you so much for your help!
