I have these two converters. Why would I need the new canon 2 and 3 converters. Are they that much better then the originals?
I have the older Canon EF 1.4X and the newer EF 1.4X III and I feel the III produces a sharper image and offers quicker AF.
That being said, I'm not sure there is an absolute necessity to run right out and upgrade.
What lens are you using these with?
I am using a canon 300 f4 lens at this time.
Ok that's great. I use both the older and the newer 1.4 on a 300 4 with great success.
