Which Canon Extender?

Just so everyone knows: The Tamron SP 1.4x and the Kenko 300 DG Pro 1.4x are the same teleconverter....just different colors.

My 70-200mm f/4 IS USM "L" lens will be here today!

This is my first "L" lens.

My plan along along was to buy an extender for it for all the obvious reasons one would.

I thought I would get the 2X II but I see many recommending the 1.4X instead.

What are the advantages and disavantages, if any, to either from those who have them and use them on a similar lens?

BTW, it one or the other, not both.

Thanks.

You made the right decision buying that L lens. Add the 1.4 to your gear list and you have a very versatile combination with constant aperture 5.6, IS and still very fast focus

Thanks everyone for your thoughts and recommendations.

The 70-200 came yesterday. I was able to get a few shots with it before dark. Very nice but we, it and I, need to spend some time together before we work well together and I order the 1.4x extender.
