Im going to be in the market soon for a converter, Ive looked at the canon 1.4 x converter and the 2 x converter, I see they are now available in versions 1, 11 and 111 which one would you advise and why. Im leaning to the 1.4 x so as not to loose to much detail Is there much difference between the 3 versions in either size.

Thanks
 
Putting an extender/teleconverter on any lens will adversely affect that image. It may be that the image degradation will not be noticed by the human eye.
This may happen with a very high quality prime lens such as a Canon 300mm f2.8 or a high quality zoom such as the various forms of the Canon 70-200 lens.
This is not an absolute list and I'm sure many folk here would say their lenses are similarly unaffected.

However, when an extender is put on many other lenses the quality degradation is such that it is immediately noticeable.
You must satisfy yourself that the lenses you already own do not fall into that category.
As for the difference between the flavours of Canon extenders you mention I would suggest doing a Google search as this extensively covered in the web.

If you do decide to try one then you could also consider an alternative brand such as Kenko, particularly for a 1.4x.
 
All I will say is that I use a 1.4 Mk3 Canon extender on my Canon EF70-200mm F2.8 and all things being equal, I really cannon tell the difference between shots with or without the extender, even at 100% crop. In fact I have just entered a natural history competition with a shot of a duck with this very combination. I can count the fronds on each feather.

Im going to be using it on the canon 70-200mm f4 L USM
Will the kenko work on this lens ??
 
I use the 1.4 mk3 and I have used it on both the 400mm 2.8 and the 70-200 and to be honest, it is really difficult to see the difference...it is a really quality piece of kit. I'm just miffed that I loose a stop of control with it.
 
I've got a Kenko Pro300 DGX 1.4x and a Canon MkIII 2x converters. The Canon is basically reserved for my 70-200 f2.8L MkII but the Kenko gets used on nearly all the other lenses I've got. It'll work on the 70-200 f4L without a problem and you'll hardly see any image degradation or AF speed drop.

From what I can gather regarding the different marks of the Canon the MkIII is the best for corner sharpness and allows faster AF than the MkII. I can't find much info on the MkI now but I would think the MkIII would be the best of the bunch. My MkIII 2x is very good on my 70-200 f2.8L MkII, much better IQ than I got with the f2.8 MkI.
